The thermal valve driver 34 controls the thermal valve 70.

Next, the operation of this embodiment will be described.

FIG. 4 is a flow chart at the time of floor heating and air conditioner interlocking operation.

In step S41, the state of the driving key 2a is judged, and by turning it on, the driving lamp 3 and the interlocking lamp 4 are turned on. In step S42,
Based on the deviation between the room temperature and the set temperature detected by the room thermistor 7, hot water supply to the floor mat 60 as a radiator for floor heating is controlled by turning the thermal valve 70 on and off.

In this control, for example, the thermal valve 70 is continuously turned on until the set temperature is reached, and on / off control is performed within the range of the set temperature plus the set value plus 2 degrees. Then, the indoor temperature is controlled while switching on and off at 5 minute intervals from 5 minutes on to 20 minutes continuous on every 1 minute.

In step S43, when the operation key 2a is on and it is determined by the answerback signal of the teleconverter 20 that the air conditioner 10 as the indoor unit is off, the process proceeds to step S44 and a teleconverter signal pulse is output. To do. If it is determined in step S43 that the air conditioner 10 is on, it is determined that the infrared remote controller 40 is on, and the teleconverter signal pulse is not output.

When the operation key 2a determines that the operation is off in step S41, the process proceeds to step S45 to send a floor heating stop signal to turn off the operation display. When it is determined in step S46 that the air conditioner 10 is on, the process proceeds to step S47, where a teleconverter signal pulse is output, and if it is off, the teleconverter signal pulse is not output.

FIG. 5 is a flow chart during the floor heating independent operation.

In step S51, the process proceeds to step S52 or step S53 depending on the on / off state of the driving key 2a. In step S52, the floor heating operation signal is transmitted from the deviation between the set temperature and the current temperature, and the operation display is turned on. However, if the current temperature is equal to or higher than the preset temperature, the on / off time of the thermal valve 70 is controlled in a cycle of 20 minutes to control the room temperature to maintain the preset temperature.

FIG. 6 is a flow chart when the air conditioner operates independently.

When the operation key 2a is turned on in step S61, the process proceeds to step S62, and it is determined whether the operation is an on operation or an off operation. If it is an on operation, the process proceeds to step S63, and if it is an off operation, the process proceeds to step S65. In step S63, it is determined whether the indoor unit 10 is in the operating state, and the operation lamp 3 and the air conditioner lamp 6 are turned on. Then, when it is detected by the answerback signal of the teleconverter 16 that the operation of the indoor unit 10 is off, the teleconverter signal pulse is given only for about 300 msec.
Output.

The indoor unit 10 starts "automatic operation" by input of a teleconverter signal pulse, and performs "heating", "dry", "cooling", etc. according to the room temperature at the start of the operation.

Even if the operation of the operation key 2a by the system remote controller 20 is an off operation in step S62, it is determined in step S65 whether or not the indoor unit 10 is in an operation state, and the same operation as the above-described on operation is performed. If the indoor unit 10 is on, a teleconverter signal pulse is transmitted in step S66 to stop the operation of the indoor unit 10. The determination delay timer is set in steps S64 and S66.

The above is the independent operation of the air conditioner 10 by the system remote controller 20. Next, the infrared remote controller 4
The operation of the indoor unit 10 by 0 will be described.

At step S67, it is confirmed that the judgment delay timer has expired. Here, first, when the indoor unit 10 is switched from off to on by the infrared remote controller 40, step S
From step 70 to step S71, the system remote controller 2
The operation display of 0 is also turned on. That is, the driving lamp 3,
Various display contents of the air conditioner mode lamp 6 and the liquid crystal display unit 1 are turned on. Then, the process does not proceed to step S68 until the judgment delay timer set to about 1 second expires.
The change in the driving state is not judged. Even if the operating state of the system remote controller 20 is off in step S72, it is determined in step S73 whether or not the timer has expired, and the operation lamp of the system remote controller 20 is turned off contrary to the case where the above-described on operation is performed. To Also,
In step S69 and step S72, a change in the operating state is determined, and if it is changed, the process proceeds to step S75. As a result, the operation change timer is set, so that no malfunction occurs even if the operation key 2a is continuously operated for a short time from the system remote controller 20 or noise is received.

The heat source unit 30 is the system remote controller 2
0 and air conditioner 10 exchanges temperature data with two-way communication, which generates hot water at the optimum temperature,
It is supplied to the floor mat 60 and the indoor unit 10.

The present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the gist of the present invention.

For example, although the infrared remote controller 40 is used as the first remote controller in the above-described embodiment, the present invention is not limited to this, and any means for controlling the operation of the air conditioner for heating the room may be used. Well, the same effect can be obtained.
