The expansion tank 8 and the water supply valve 9 are provided in the supply water inlet pipe 7 connected to the heating return pipe 3.

要がなく、スムーズに行われるものである。In such a hot water circulation type heating system, the room temperature T is detected, a preset temperature Ts is compared with the room temperature T, and the opening and closing of the thermal valve 5 is determined based on the deviation ΔT = T−Ts. It is determined by changing the time (see FIG. 5). For example, when ΔT = 1.66 to 2.15 deg., The open time (ON time) of the thermal valve 5 is 5 minutes, and the close time (OFF time) is 15 minutes. In such a control method in which the opening and closing time of the thermal valve 5 is determined by the deviation ΔT, when the deviation ΔT is relatively large, it is not necessary to determine a severe control stage, and the control is performed smoothly.

When the room temperature T does not reach the set temperature Ts and the room temperature T is stabilized with a certain deviation ΔT, the opening and closing time of the thermal valve cannot be changed, and the room temperature T is changed to the set temperature Ts.
Has been difficult to reach. In addition, the opening and closing time of the thermal valve that stabilizes the room temperature T should be different depending on the heat radiation amount of the living room and the set temperature Ts.
The control stage determined only by itself does not take the heat radiation amount of the living room and the set temperature Ts into consideration, and thus has a problem that the room temperature T cannot be stabilized at the set temperature Ts under all conditions.

とができる。Since the present invention is configured as described above, it has the following effects. In claim 1, a plurality of temperature regions based on the set temperature are determined, and the opening of the thermal valve within one operation cycle (O) is performed according to the region where the current room temperature is located.
N) time and closing (OFF) time are varied,
By adjusting the opening (ON) time and closing (OFF) time of the thermal valve in accordance with the fluctuation direction of the room temperature in the same area, the room temperature is adjusted to the set temperature regardless of the set temperature, the amount of heat released from the living room, etc. , Can be stabilized. In claim 2, during the opening (ON) or closing (OFF) operation of the thermal valve,
When the room temperature reaches the set temperature, the operation is shifted to the closing (OFF) operation during the opening (ON) operation of the thermal valve, and to the opening (ON) operation during the closing (OFF) operation, thereby reducing the room temperature. The occurrence of overshoot or undershoot can be prevented.
