Description

  The present invention relates to a control device for a heating system such as a floor heating remote controller.

  As conventional floor heating systems, those disclosed in Patent Documents 1 to 4 below are known.

Japanese Patent No. 3636249 Japanese Patent No. 4030709 JP 2002-139226 A Japanese Patent No. 4157074 Japanese Patent Laid-Open No. 2001-4158

  Patent Documents 1 to 3 disclose a remote controller for operating a floor heating system including a plurality of floor heating terminals.

  In the floor heating system described in Patent Document 1, one floor heating panel (heating terminal) and a remote control device (remote control) are provided for each of a plurality of living rooms (1 to N). Connected to two heat source units and configured to request high or low temperature hot water supply from the control unit of each remote control device, and output from the heat source unit when the high temperature requirement and the low temperature requirement compete The temperature of the hot water is set to a predetermined temperature.

  Moreover, the floor heating system described in Patent Document 2 includes a floor heating controller (remote control) that controls a plurality of hot water mats (heating terminals) arranged on the floor of one living room, When operating all of the multiple systems, room temperature control is performed to warm the floor based on the difference between the set temperature of the room temperature and the measured temperature.When operating part of the multiple systems, the floor is controlled based on the set temperature. The fixed control for warming is performed.

  In addition, the floor heater disclosed in Patent Document 3 uses a plurality of floor heating units (heating terminals) to heat one room divided into a plurality of heating areas, and each floor heating unit is independent. Heating control means for controlling the operation and a remote controller for remotely controlling the heating control means.

  Patent Document 4 or 5 discloses a floor heating system in which hot dash operation control for supplying a heat medium having a temperature higher than that during normal operation is performed immediately after the start of operation.

  The remote control disclosed in each of the above Patent Documents 1 to 3 is configured as a dedicated device when a plurality of heating terminals are in a specific arrangement. For example, the remote control described in Patent Document 1 is provided in one living room. It cannot be used for controlling a plurality of heating terminals, and the remote control described in Patent Document 2 or 3 is not designed to control a plurality of heating terminals distributed and installed in a plurality of living rooms. .

  On the other hand, new housings in recent years are often designed with room allocation according to the client's request, and the size of each room and the number of rooms are diversifying, and accordingly, the floor heating system is also required to be diverse. At the same time, there is a need for a flexible floor heating system configuration that meets the client's needs even during expansion and renovation. In addition, by installing multiple floor heating terminals in a large living room such as a living room, it is possible to heat only a part of the living room or to heat the whole according to the lifestyle, There is a desire to install floor heating terminals in another room that is spatially separated from the living room, and to operate a plurality of floor heating terminals distributed and installed in the plurality of rooms with a single remote controller.

  By the way, in recent floor heating systems, it is common to perform hot dash control as disclosed in Patent Document 4 or 5 by using a remote controller. For example, a plurality of floor heating terminals are installed in the living room. In such a case, when only some of the systems are operated first and a certain amount of time has passed and the operation of the floor heating terminal of the other system is started, the room temperature has already risen to some extent. If the hot dash operation is continued for the same time as the hot dash operation of the floor heating terminal that was driving first, the floor surface will be too warm, which may cause discomfort to the user, and more than necessary There is a problem that running cost is increased because high temperature water is supplied.

  For this reason, a control that links multiple systems of floor heating terminals and shortens the hot dash operation time when starting another floor heating terminal when one floor heating terminal is already in operation, etc. However, when another floor heating terminal is installed in another room, it may not be desired to shorten the hot dash operation time at the start of the operation.

  Therefore, the present invention makes it possible to control a heating system that performs heating operation control such as hot dash operation control for each system by distributing and installing a plurality of heating terminals to a plurality of living rooms with one control device, and is also requested by the user. The purpose is to enable each system to be linked or operated independently.

  In order to achieve the above object, the present invention takes the following technical means.

  That is, the present invention is a control device for a heating system in which a plurality of heating terminals distributed and installed in at least two living rooms are connected to a common heat source machine, and the initial operation start of each system is from the heat source machine. Heating operation control is configured for each system so that hot dash operation control for supplying a relatively high temperature heat medium is performed, and then normal operation control for intermittently supplying a relatively low temperature heat medium from a heat source machine is performed. In the control device, as the control content of the hot dash operation control at the beginning of the operation of the heating terminal of each system, either the predetermined isolated operation control content or the predetermined linked operation control content different from the isolated operation control content is predetermined. Control content selection means for automatically selecting based on the conditions of the same, and the same room setting means for presetting whether the heating terminals of each system are installed in the same room as the heating terminals of other systems , Hot dash setting means for presetting whether to enable or disable the hot dash operation control for each system, and determining whether the heat medium supplied from the heat source unit is relatively high temperature or relatively low temperature Heat medium temperature determining means, and temperature adjustment control means for changing the duty ratio of intermittent heat medium supply from the heat source unit based on the determination result of the heat medium temperature determining means during normal operation control of each system In addition, the control content selection means is configured such that the linked operation control content is selected only when it is set by the same room setting means that a heating terminal of another system is installed in the same room. It is configured that normal operation control is started without performing hot dash operation control at the start of operation of the heating terminal of the system disabled by the hot dash setting means It is an symptom (claim 1).

  A specific example of the control device for the heating system according to the present invention is a remote controller that sends various control commands to a heat source device controller such as a hot water supply control device built in the heat source device, and the remote control (heating control device) is a user. The heat source controller can perform low-level control on each control device such as a heat operated valve and a combustion device.

  The specific contents of the independent operation control contents and the linked operation control contents may be anything, and these names are not intended to limit the present invention to the embodiments described later, and the heating terminals of each system are operated independently. What is necessary is just the content of the control in the case of driving | running, and operating the heating terminal of each system | strain, performing some (predetermined) cooperation with the heating terminal of another system | strain. For example, the content of the independent operation control is that the hot dash operation time is relatively long (for example, 60 minutes), and the content of the linked operation control is that the heating terminal of any other system is in normal operation. As the “predetermined condition”, the hot dash operation time can be a relatively short time (for example, 30 minutes).

  Each of the above-mentioned means can be realized preferably by a CPU that executes a program stored in the storage means, but may be constituted by a dedicated electronic circuit, or a hot dash setting. The means and the same room setting means may be configured by a switch such as a dip switch. In addition, since the living room where a plurality of heating terminals are installed is often only the living room, whether or not the same living room setting means is installed in one specific room (for example, a living room) among the plurality of living rooms. May be set, and in which room is installed for each heating terminal of each system may be set. Moreover, as a heating terminal, low temperature heating terminals, such as a floor heating terminal and a wall heating terminal, can be used suitably.

  According to the control device for a heating system of the present invention, since the same living room setting means is provided, the operation in which the heating terminal of each system is linked with the heating terminal of any other system at the time of construction of the plurality of heating terminals is performed. It is possible to set whether the operation is performed independently or without being linked, and a single control device can perform various controls according to the user's request. In addition, when the heating terminal of a certain system is started to operate, the control content selection unit only sets the one when the heating terminal of another system is set in the same room by the same room setting unit. Since the control content of the hot dash operation control of the heating terminal of the system is configured to be set to the linked operation control content, for example, the heating terminal of another system installed in a different room is in normal operation control Even if the above-mentioned “predetermined condition” for making the control content of the hot dash operation control of the heating terminal of one system the linkage operation control content is satisfied, the same room setting means is set. Accordingly, it is possible to forcibly perform normal hot dash operation control by passing the determination of “predetermined conditions”. It is also possible to set “predetermined condition” as to whether or not the operating state of the other heating terminal set as the same room by the same room setting means is a predetermined state. Also, if multiple heating terminals in the same room are operated simultaneously, by selecting the linked operation control content as hot dash operation control at the start of operation of the heating terminal of the system to be started later, Overheating can be prevented, low temperature burns can be prevented, and running costs can be reduced.

  In addition, since a hot dash setting means is provided, there is no need to perform hot dash operation in the first place when a heating terminal is installed in a relatively small room, or depending on the material of the floor material installed on the upper layer of the heating terminal As for, the hot dash operation control can be disabled and various requests can be flexibly handled.

  In addition, since the temperature adjusting means is provided, the temperature of the heat medium supplied from the heat source unit to the heating terminal of the one system is raised to a high temperature by performing the hot dash operation while the other system is operating normally. Even if it becomes, the heating terminal of one system | strain can be maintained at appropriate temperature by adjusting an intermittent heating-medium supply timing.

In addition, the present invention is a control device for a heating system in which a plurality of heating terminals distributed and installed in at least two living rooms are connected to a common heat source machine, and the initial operation start of each system is hot dash operation control In the control device configured to be able to control the heating operation for each system so that the normal operation control is performed after that, as the control content of the hot dash operation control at the beginning of the operation of the heating terminal of each system, the predetermined single operation control content And control content selection means for automatically selecting any of the predetermined linked operation control content different from the content of the independent operation control based on a predetermined condition, and the heating terminal of each system in the same room as the heating terminal of the other system Same room setting means for presetting whether or not installed, and hot dash for presetting whether to enable or disable the hot dash operation control for each system Control content selection means, so that the linked operation control content is selected only when it is set by the same room setting means that a heating terminal of another system is installed in the same room. It is configured, and is configured to start normal operation control without performing hot dash operation control at the start of operation of a heating terminal of a system disabled by the hot dash setting means (Claim 2 ).

  According to the present invention, since the same living room setting means is provided, at the time of construction of the plurality of heating terminals, the heating terminal of each system is operated or not linked with the heating terminal of any other system. It is possible to set whether to perform the operation independently, and it is possible to perform various controls according to the user's request with a single control device. In addition, when the heating terminal of a certain system is started to operate, the control content selection unit only sets the one when the heating terminal of another system is set in the same room by the same room setting unit. Since the control content of the hot dash operation control of the heating terminal of the system is configured to be set to the linked operation control content, for example, the heating terminal of another system installed in a different room is in normal operation control Even if the above-mentioned “predetermined condition” for making the control content of the hot dash operation control of the heating terminal of one system the linkage operation control content is satisfied, the same room setting means is set. Accordingly, it is possible to forcibly perform normal hot dash operation control by passing the determination of “predetermined conditions”. It is also possible to set “predetermined condition” as to whether or not the operating state of the other heating terminal set as the same room by the same room setting means is a predetermined state. Also, if multiple heating terminals in the same room are operated simultaneously, by selecting the linked operation control content as hot dash operation control at the start of operation of the heating terminal of the system to be started later, Overheating can be prevented, low temperature burns can be prevented, and running costs can be reduced.

It is possible to set whether to operate in conjunction with the heating terminal of the grid or to operate independently without linking, and with a single control device, various controls are performed according to the user's request. Can be made. In addition, when the heating terminal of a certain system is started to operate, the control content selection unit only sets the one when the heating terminal of another system is set in the same room by the same room setting unit. Since the control content of the hot dash operation control of the heating terminal of the system is set to the linked operation control content, the judgment of “predetermined condition” is passed and forced according to the setting of the same room setting means Therefore, normal hot dash operation control can be performed. It is also possible to set “predetermined condition” as to whether or not the operating state of the other heating terminal set as the same room by the same room setting means is a predetermined state. Also, if multiple heating terminals in the same room are operated simultaneously, by selecting the linked operation control content as hot dash operation control at the start of operation of the heating terminal of the system to be started later, Overheating can be prevented, low temperature burns can be prevented, and running costs can be reduced.

And a hot water supply control device for controlling the hot water supply temperature switching device 6 that discharges from the forward header 5 as low temperature water having a relatively low temperature (for example, 60 ° C.), the return header 7, the combustion device, and various electromagnetic valves. 8 and. The forward header 5 and the return header 7 are provided with a connection port and an electromagnetic on-off valve or a thermal valve (not shown) for each system, and the floor heating panel 2 of each system goes to the forward header 5 and the return header 7. The high temperature water or the low temperature water supplied from the supply hot water temperature switching device 6 can be turned on and off for each system.

  In addition, although not shown in figure, the hot water supply apparatus 3 can be equipped with conventionally well-known appropriate functions, such as a general hot water supply function, a bath hot water supply function, and a bath warming function. As such a hot water supply device 3, for example, the hot water circulation type heater disclosed in Japanese Patent Application Laid-Open No. 2007-10209 by the applicant of the present application can be used, and in addition, a conventionally known appropriate hot water supply device configuration can be adopted.

  The hot water supply control device 8 is electrically connected to the floor heating remote control 1, and the hot water supply control device 8 controls various devices to be controlled in the hot water supply device 3 based on a command signal from the floor heating remote control 1. Further, the hot water supply control device 8 is configured to send out the hot water temperature information from the supplied hot water temperature switching device 6 to the outgoing header 5, temperature information from the temperature sensor, and the like to the floor heating remote controller 1.

  As shown in FIGS. 2 to 5, the floor heating remote controller 1 is provided with a liquid crystal display device and various operation buttons on the front surface, and a storage means such as a CPU, a RAM and a ROM, a liquid crystal controller, an input / output controller, and the like. The heating operation control program that is provided and stored in the storage means, as shown in FIGS. 6 to 8, at the beginning of operation of the floor heating panel 2 of each system is relatively hot (for example, 80 ° C.) from the hot water supply device 3. ) Is heated for each system so as to perform normal operation control for intermittently supplying hot water at a relatively low temperature (for example, 60 ° C.) from the hot water supply device 3. Operation control is possible.

  Further, the floor heating remote controller 1 is configured to perform a floor heating operation operation, a reserved operation setting operation, a hot dash invalid setting operation, and an identical room setting operation through various operation setting screens. FIG. 2 shows the floor heating operation operation screen, and it is possible to set whether or not to operate the floor heating panel 2 for each system, and in the case of operation, the set temperature is set to high, medium and low. The setting contents set here are stored in the storage means. Further, the floor surface temperature of each system is displayed as a meter based on the detected temperature signal from the temperature sensor of each system 1.

  FIG. 3 shows a reserved operation setting screen, in which the time for starting the reserved operation and the system for the reserved operation can be set. The reserved time set here and the setting information for each system are stored in the storage means. Is remembered. The control program is configured to start the operation of the floor heating panel 2 of the set system when the reserved operation is started when the built-in clock of the floor heating remote controller 1 is set. The common reservation operation control means for starting the heating operation control of a predetermined plurality of heating terminals at a predetermined time set by the CPU that executes the control program is realized.

  FIG. 4 shows a hot dash setting screen for setting whether to enable or disable the hot dash operation for each system, and the hot dash settings for each system set here are also stored in the storage means. The control program is configured so that the hot dash setting means is realized by the CPU that executes the control program.

  FIG. 5 shows whether or not the linked operation is performed in order to link the hot dash operations of the plurality of floor heating panels 2 installed in the same room, that is, whether or not the system is installed in a specific living room. The same room setting screen to be set is shown, and the same room setting for each system set here is stored in the storage means, and the control room is configured by the CPU that executes the control program. Means are realized. In the illustrated example, the same room setting for systems 1 and 2 installed in the living room is set to “ON”, and the same room setting for systems 3 and 4 installed in rooms other than the living room is set to “OFF”. ing.

  FIG. 6 shows a control flow of the heating operation control of the floor heating panel 2 of each system, and the operation setting of each system is changed from “stop” to “high”, “medium”, “on” on the floor heating operation screen shown in FIG. The system operation is started by switching to one of “low”. When the system operation is started, first, in step S1, it is determined by referring to the storage means whether the hot dash setting of the system is valid or invalid, and if it is valid, the hot dash operation control in step S2 is performed. If it is invalid, step S2 is passed and control is branched to normal operation control in step S3. After the hot dash operation control in step S2 is executed, the process proceeds to step S3, where the normal operation control is executed, and the system operation is terminated when the operation stop operation of the system is performed.

FIG. 7 shows a control flow of hot dash operation control. First, in step S4, it is determined whether the same room setting of the system is “ON” or “OFF”. If “OFF”, the process branches to step S7.

  In step S5, when the floor heating panel 2 of the system in which the same living room is set as described later is in normal operation, the hot dash shortening mode flag stored in the storage means corresponding to that system is set to ON. It is determined whether the hot dash shortening mode flag of any system is ON. In this embodiment, the hot dash shortening mode flags of all the systems are referred to. However, in the normal operation control of the systems 3 and 4 installed in the study or bedroom other than the living room, these systems 3 and 4 include Since the same room setting has not been made, the hot dash shortening mode flag will not be turned on. Therefore, a determination based on the hot dash shortening mode flag of the systems 1 and 2 installed in the living room is made in step S5. Will be.

  If it is determined in step S5 that the hot dash shortening mode flag of any system is ON, the process branches to step S6 for setting the hot dash shortening operation mode (linked operation control content), and all the flags are OFF. If it is determined, the process branches to step S7 for setting the hot dash normal operation mode (independent operation control content).

  In step S6, hot dash shortening operation time (for example, 30 minutes) is set to the target time variable Tg memorize | stored in a memory | storage means. On the other hand, in step S7, the hot dash normal operation time (for example, 60 minutes) is set in the target time variable Tg. Thus, by the control program for executing these steps S5 to S7, the hot dash shortening operation time (linked operation control) is set as the operation time (control content) of the hot dash operation control at the beginning of the operation of the floor heating panel 2 of each system. Content) and hot dash normal operation time (independent operation control content) is configured to automatically select control content during operation control based on a predetermined condition. The linked operation control content is selected only when it is set by means that a heating terminal of another system is installed in the same room.

  After step S6 or step S7 is executed, a timer T is initialized in step S8. The target time variable Tg and the timer T are separately provided for each system.

  Next, in step S 9, a command signal for starting the hot dash operation of the system is sent to the hot water supply control device 8, and the hot water supply control device 8 that receives the signal sends the hot water temperature supplied from the supplied hot water temperature switching device 6. Is controlled to a high temperature (80 ° C.), and an electromagnetic on-off valve corresponding to the system is opened to start supplying hot water to the floor heating panel 2 of the system. When hot dash operation control of a plurality of systems is being executed, the hot water supply control device 8 increases the hot water temperature sent from the supplied hot water temperature switching device 6 until the hot dash operation of all the systems ends. Configured to maintain.

  Next, in step 10, it is determined whether or not a predetermined hot dash operation time has elapsed from the start of the hot dash operation by comparing the timer T and the target time variable Tg, and the hot dash operation time has elapsed. For example, the process proceeds to step S12 to stop the hot dash operation of the system. On the other hand, when the hot dash operation time has not elapsed, the process proceeds to step S11 to determine whether or not there is a request to stop the hot dash operation. Such a stop request may be due to a user operation of the remote controller 1, or may be a command signal sent from the hot water supply control device 8 to the remote control due to an abnormality in the hot water supply device. The remote controller 1 may request itself based on the temperature detected by the temperature sensor of the floor heating panel of the system. If there is no such stop request, the process returns to step S10, and if there is a stop request, the process proceeds to step S12 to stop the hot dash operation.

  In step S12, a command signal for stopping the hot dash operation of the system is sent to the hot water supply control device 8, and the hot water control device 8 receiving the signal closes the electromagnetic on-off valve corresponding to the system and closes the floor of the system. While the supply of hot water to the heating panel 2 is temporarily stopped, the hot water temperature supplied from the hot water supply temperature switching device 6 is controlled to a low temperature (60 ° C.) if there is no other system performing hot dash operation.

  FIG. 8 shows a control flow of normal operation control.

  When normal operation control of the system is started, first, in step S13, it is determined whether or not the same room setting of the system is set to “ON”. If “ON”, the system is installed in the same room. In step S14, the hot dash shortening mode flag of the relevant system is set to ON so that the hot dash operation time when the other system is started to operate with a delay can be controlled. In the present embodiment, the hot dash shortening mode flag is individually stored in the storage means for each system, but it may be configured to be controlled by only one hot dash shortening mode flag.

  If the same room setting is set to “OFF” in step S13, and after execution of step S14, the process proceeds to step 15 and a command signal for starting normal operation of the system is sent to the hot water supply control device 8. The hot water supply control device 8 that has sent out and received the signal starts the control necessary for normal operation.

  Next, in step S16, the timer T is initialized, and then in step S17, it is determined whether the hot water temperature sent from the supplied hot water temperature switching device 6 is high or low. Thus, a hot water temperature determination means for determining whether the hot water supplied from the hot water supply device 3 is relatively high temperature or relatively low temperature is configured by the program for executing step S17.

  If the supplied hot water temperature is high, the process branches to step S18, and the value of the high temperature hot water supply duty time function fh (t) is set in the target time variable Tg. On the other hand, if the supplied hot water temperature is low, the process branches to step S19, and the value of the low temperature hot water supply duty time function fl (t) is set in the target time variable Tg. These functions fh (t) and fl (t) are based on the set temperature of the system set on the floor heating operation screen shown in FIG. 2, the detected temperature t of the temperature sensor of the floor heating panel 2 of the system, and the like. An appropriate duty time is output in accordance with a state that changes from moment to moment, and the value of the hot water supply duty time function fh (t) is higher than the value of the low temperature hot water supply duty time function fl (t). small. Each function is set so that the values of these functions are smaller than the control cycle time described later.

  Thus, the duty ratio of intermittent hot water supply from the hot water supply device 3 is automatically adjusted as needed based on the determination result of the hot water temperature determination means during the normal operation control of each system by the control program for executing step S18 or S19. A temperature adjustment control means to be changed is configured.

  Next, in step S20, it is determined whether or not the timer T has passed the target time Tg. If not, in step S21, a request signal is sent to the hot water supply control device 8 to supply hot water to the system. If it has elapsed, a request signal for stopping the supply of hot water to the system is sent to the hot water supply control device 8 in step S22.

  Next, in step S23, it is determined whether or not the timer T has passed a control cycle time (for example, 20 minutes). If it has elapsed, the process proceeds to step S24 to initialize the timer T and then to step S25. If not, the process proceeds to step S25 without initializing the timer.

  In step S25, it is determined whether there is a normal operation stop request. Such a stop request may be due to a user operation of the remote controller 1, or may be a command signal sent from the hot water supply control device 8 to the remote control due to an abnormality in the hot water supply device. The remote controller 1 may request itself based on the abnormal detection temperature of the temperature sensor of the floor heating panel of the system. If there is no such stop request, the process returns to step S17 and repeatedly executes steps S17 to S25. If there is a stop request, the process proceeds to step S26 to stop the normal operation.

  In step S26, a command signal for stopping the normal operation of the system is sent to the hot water supply control device 8, and the hot water supply control device 8 receiving the signal closes the electromagnetic on-off valve corresponding to the system, and the floor heating panel 2 of the system. Necessary stop control such as stopping the operation of the high-temperature water supply device 4 is performed if there is no other operating system.

  Finally, in step S27, the hot dash shortening mode flag of the system is set to OFF, and the normal operation control ends. In this embodiment, the hot dash shortening mode flag is set on / off depending on whether each system is in normal operation. For example, whether the room temperature exceeds a predetermined threshold regardless of the heating operation control of each system. It is also possible to configure the hot dash shortening mode flag to be turned on / off depending on whether or not.

  FIG. 9 shows the floor of the system 2 (second system) installed in the same living room after the floor heating panel 2 of the system 1 (first system) installed in the living room has entered normal operation control in the above embodiment. It is a time chart which shows the state of the hot water supply of each system | strain when the heating operation of the heating panel 2 is started. As shown in the figure, at the beginning of operation of the first system, other systems in the same room are not in operation and the living room is in a cold state, and hot dash operation is usually performed to ensure sufficient heating capacity. Time (60 minutes) is performed, and then normal operation control is performed. At the initial stage of this normal operation control, the hot water supply temperature is low (60 ° C.), so the target time variable Tg is set to the value of the low temperature hot water supply duty time function fl (t) and the control cycle time (20 minutes). ) For a relatively long time.

  When the heating operation of the second system is started, the hot water supply temperature to all the systems becomes high (80 ° C.) due to the hot dash operation at the initial stage of the operation start. In step S18, the target time variable Tg of the first system becomes the value of the hot water supply duty time fh (t). Accordingly, if the timer T of the first system exceeds the value of fh (t) at the start of operation of the second system, the hot water supply of the first system is stopped until the next cycle time is reached. .

  On the other hand, as the hot dash operation time at the beginning of the operation of the second system, since the normal operation control of the first system has already been executed, the hot dash shortening time (for example, 30 minutes) is achieved by step S5 and step S6 in FIG. Is set, and hot dash operation is performed by continuous supply of high-temperature water for a relatively short time.

  10 and 11 show a second embodiment of the floor heating remote controller 1 according to the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different configurations are provided. The effect will be described.

  In the second embodiment, by setting whether to belong to a plurality of (four in the illustrated example) groups 1-4 (four in the illustrated example) on the same room setting screen. The same room setting means is configured so that it can be set whether or not the floor heating panel 2 of each system is installed in the same room.

  Further, in the hot dash operation control, as shown in FIG. 11, the presence / absence determination of the same room setting in step S4 in FIG. 7 is omitted, and in step S5, the hot dash shortening mode flag of any system in the group to which the group belongs is set. It is determined whether or not it is ON. Even in such a configuration, an independent system (for example, systems 3 and 4 in FIG. 10) in which no other system is arranged in the same room does not have the hot dash shortening mode flag of the other system referred to. The hot dash reduction time (linked operation control content) is not selected. Therefore, with such a configuration, step S13 in the normal operation control of FIG. 8 can be omitted, and the hot dash shortening mode flag of the system can be set to ON at the beginning of normal operation control.

  The present invention is not limited to the above-described embodiment, and the design can be changed as appropriate. For example, in the above embodiment, the function of the control device of the present invention is realized only by the floor heating remote controller 1, but the present invention is realized by the heat source machine controller (hot water supply control device in the above embodiment) and the floor heating remote controller 1 built in the heat source machine. The controller of the present invention may be configured by a heat source controller.

  Further, the “control content” may be a set value such as the hot dash time of the above-described embodiment stored in the storage means for use in control, and is realized by a program stored in the storage means. It may be a control flow. That is, in the above embodiment, the control content is changed by selecting either the hot dash shortening time or the hot dash normal time as the set value of the target time variable Tg, but the control flow, that is, the program code itself to be executed is changed. It can also be configured to switch.

  Moreover, in the said embodiment, although comprised so that only the control content of the hot dash control of an operation | movement initial stage in heating operation control might be selected by the control content selection means, the control content in normal operation control is set to another system. It is also possible to apply the present invention to a device that switches between linkage and single operation.
