PURPOSE:To output instruction of operation and stopping of a compressor according to the result of comparison in the comparison of the result of detection on which temperature zone divided by temperature data stored in memory detected temperature lies and a set temperature when a turning-off timer is started and when time detection means issues detection signal. CONSTITUTION:Detection data of a timer switch 1, outdoor temperature sensor 2, and suction air temperature sensor 3 are inputted to a microcomputer 4, and ON/OFF signal of a power source 6 which supplies power to a compressor 5 is transmitted to a relay contact section 7b via a relay coil section 7a. After the timer switch 1 is ON or a specified time has passed after the ON of the timer switch 1 zone detection for outdoor temperature is carried out to determine set temperature in a room. If the outdoor temperature does not reach T0 when a turning-off timer is started, the set temperature is set at TS2 and if the temperature is over T0 and below T1, the set temperature is set at TS1, If the outdoor temperature is over T1, the set temperature is set at TS0. A similar judgement is made after a time t0 has passed after starting the turning-off time. The comparison with the set temperature that was set is carried out and on the basis of the result of this comparison the compressor is turned ON or OFF.
