A heat medium on-off valve 2 that can be supplied intermittently is provided. The temperature in the room A is detected by temperature detecting means 12 (see FIG. 1) composed of a temperature sensor.

The water heater 3 is provided with a heat exchanger using a gas burner as a heat source, and water passing through the heat exchanger is heated by the gas burner. In the present embodiment, the water heater 3 and the heat medium on-off valve 2 constitute a heat source device that supplies a heat medium to the floor heating panel 4.

The heating medium on-off valve 2 and the water heater 3 are
It is controlled by the floor heating control device 1. Floor heating control device 1
Has a control means 11 constituted by a microcomputer or the like as shown in FIG.
Accordingly, at least one of the heating medium on-off valve 2 and the water heater 3 is controlled.

As shown in FIG. 1, the floor heating control device 1 includes a temperature detecting means 12 comprising a temperature sensor for detecting the room temperature of the room A, and a target temperature of the room temperature of the room A by manual operation of a user. A temperature setting means 13 for setting the time, a time counting means 14 for limiting a preset forced operation time,
An operation switch (not shown) for instructing operation start and operation stop.

Next, the basic operation of the floor heating device of the present embodiment will be described with reference to FIG.

First, when the start of operation is instructed by the operation switch, the control means 11 determines the forced operation time based on the temperature detected by the temperature detection means 12, and then the gas burner of the water heater 3 is ignited and specified. The water heater 3 is controlled so as to discharge hot water (heat medium) having the highest temperature, and the flow control valve 2 is controlled so as to be fully opened (S1), and the timer 14 starts counting elapsed time. Here, the control means 11 operates the heat source device so as to supply the specified maximum temperature hot water to the floor heating panel 4.

The control means 11 operates the heat source device at the maximum capacity until the time counted by the time counting means 14 reaches the forced operation time, and the time counted by the time counting means 14 reaches the forced operation time. (S2) After that, the amount of heat given to the floor heating panel 4 from the heat source device to the floor heating panel 4 is adjusted so that the temperature detected by the temperature detecting means 12 becomes a preset target temperature (S3, S6). When the temperature reaches the target temperature (S3), control is performed to close the heat medium on-off valve 2 (S4). The timer 14 is reset when the forced operation time is reached.

In adjusting the heat quantity (S6),
The calorie of the heat source device is determined based on the difference between the temperature detected by the temperature detecting means 12 and a preset target temperature, and the heating power of the gas burner is adjusted so as to obtain the calorie, or the heat medium on-off valve 2 Adjust the opening and closing time of the. If the operation switch has been turned on (S5), the process returns to S3. By the way, since the control means 11 sets the above-mentioned forced operation time according to the temperature detected by the temperature detection means 12, when the difference between the target temperature and the room temperature is large, the heat source device is controlled so that the forced operation time becomes longer. As a result, the rise time at room temperature can be shortened, and the usability is improved. Further, the control unit 11 includes a rising time measuring unit (not shown) for measuring a time required for the temperature detected by the temperature detecting unit 12 to rise by a certain temperature during the forced operation time after the start of the operation. A non-volatile memory such as an EEPROM for storing the time measured by the rise time measuring means, and setting the length of the forced operation time according to the length of the time stored in the non-volatile memory during the previous operation. Is to be adjusted. That is,
The control unit 12 determines the forced operation time based on the temperature detected by the temperature detection unit 12 and the time stored in the nonvolatile memory. The longer the time stored in the nonvolatile memory is, the more the forced operation is performed. Longer driving time,
Since the forced operation time is shortened as the time stored in the nonvolatile memory is shorter, excessive temperature rise or insufficient temperature rise due to external influences and the like are less likely to occur.

Here, the floor heating control device 1 includes date and time management means for managing the date and time.
The length of the forced operation time is determined according to the length of time required for the temperature detected by the temperature detection means 12 to rise by a certain temperature in the time zone closest to the operation day other than the current day based on the output of the date and time management means. , It is possible to perform appropriate floor heating according to the use condition.
