PURPOSE:To eliminate the temperature error, which may occur at conventional room temperature control by utilizing thermostat, by a method wherein the ratio of running time and down time is made variable by means of a timer. CONSTITUTION:A down time zone A and a running time zone B are set by means of the timer. Concretely, when a timer division is set, for example, at 6, the operation is performed for 16min and represented by the point (a) and, after that, the down time of 15min follows. Further, when the timer division is set, for example, at 7, the running time is 21min and the point (b) is attained by being followed with the down time of 9min after that. A comfortable temperature control can be performed by properly selecting said timer division. |
