Control signals are output to the water filling lamp 46 and the emergency operation lamp 47.

  With the above configuration, the heating control will be described based on the flowchart as shown in FIG. First, the microcomputer 41 selects the initialization of the system number, that is, the control for the floor heating panel 5, and determines whether or not the operation switch 18b of the central remote controller 18 is operated. If it is determined that it is not in operation, it is next determined whether or not the corresponding floor heating remote controller 19 is in operation. If it is not in operation, the thermal valve 11 of the system number is turned off.

  Similarly, when the microcomputer 41 selects the control for the floor heating panel 5 and determines that the operation switch 18b of the centralized remote controller 18 is not operating by operation, and determines that the corresponding floor heating remote controller 19 is operating, It is determined whether or not the corresponding thermal valve 11 of the corresponding floor heating panel 5 is turned on (ON) in the on / off duty control. Otherwise, the corresponding thermal valve 11 is turned off. That is, the thermal valve 11 corresponding to the floor heating panel 5 is duty-controlled by the microcomputer 41 as will be described later.

  Similarly, when the microcomputer 41 selects the control for the floor heating panel 5, it is determined that the operation switch 18b of the centralized remote controller 18 is in operation, and the corresponding floor heating remote controller 19 is also in operation. It is determined whether or not the corresponding thermal valve 11 of the corresponding floor heating panel 5 is ON / OFF duty control, and if it is during the ON timing, the corresponding thermal valve 11 is turned on and the ON timing is reached. If not, the corresponding thermal valve 11 is turned off. That is, the thermal valve 11 corresponding to the floor heating panel 5 is duty-controlled by the microcomputer 41.

  Similarly, when the microcomputer 41 selects the control for the floor heating panel 5 and determines that the operation switch 18b of the centralized remote controller 18 is in operation, and determines that the corresponding floor heating remote controller 19 is not in operation, It is determined whether central control by the central remote controller 18 is to be performed (valid) or not (invalid). The microcomputer 41 determines the setting contents by the setting device 24 from the state of the dip switch 24A.

  When the control process for the floor heating panel 5 is finished, the system number is updated, and if the process for the floor heating panel 8 of the final system number is not finished, the control process for the next floor heating panel 6 is performed, Control processing of the heating panels 7 and 8 is performed.

  And when the system number is updated and the processing for the floor heating panel 8 of the final system number is completed, when it is determined that any one of the floor heating remote controllers 19 to 22 or the centralized remote controller 18 is in operation, The outdoor unit 1 operates for heating and the circulation pump 9 operates.

  That is, the compressor in the outdoor unit 1 is operated and high-temperature and high-pressure refrigerant is supplied to the refrigerant-side coil 4A of the heat exchanger 4 to heat the heating circulating water flowing through the hot-water side coil 4B and to set the corresponding thermal valve. The microcomputer 41 is turned on to open and operate the circulating pump 9 of the hot water unit 3 so that the temperature of the heated circulating water detected by the thermistor 15 becomes the set temperature 60 ° C. set by the knob 18a of the central remote controller 18. However, for example, the amount of heating in the heat exchanger 4 is controlled by inverter-controlling the compressor, and hot water adjusted to 60 ° C. is circulated in the circulation path including the corresponding floor heating panel.

  Next, duty control of the thermal valve by the microcomputer 41 will be described. The floor heating remote controllers 19 to 22 corresponding to the floor heating panels 5 to 8 that are duty-controlled detect the room temperature rise by the room temperature sensors 19b to 22b, and the temperature deviation (room temperature-set temperature) is -1.15 ° C. (deg). If it exceeds, the analog output voltage output to the microcomputer 41 is changed in the range of 20V (volt) to 9V. The microcomputer 41 duty-controls the energizing time of the thermal valves 11-14 according to the analog voltage value output from the floor heating remote controllers 19-22, and sets the open time of the thermal valves 11-14 to, for example, 20 By controlling as a set time between 20 minutes (continuous) and 3 minutes every minute, the hot water supply is intermittently turned on and off to maintain the room temperature in the A to D rooms at the set temperature. .

  In this way, due to the temperature deviation between the room temperature output from the floor heating remote controllers 19, 20, 21, 22 arranged in the respective A, B, C, D rooms and the set temperature, the thermal valves 11, 12, 13, 14 By controlling the opening and closing time, the room temperature of each room can be maintained at the set temperature regardless of the hot water temperature.
