Abstract

PURPOSE: To control the indoor temperature to be comfortable by changing the set value of the indoor temperature in accordance with the outdoor temperature.
CONSTITUTION: When the indoor temperature is set by a variable resistance 27, a voltage V1 is inputted in an amplifier 14. The outdoor temperature is detected by a thermosensing element 2 and the detection signal is inputted in an amplifier 12, while the output of the amplifier 12 is inputted in the amplifier 14. The indoor temperature is detected by a thermosensing element 1 and inputted in amplifiers 15 and 16 through an amplifier 11. In the case when the indoor temperature is higher than the set temperature, a flip-flop 17 is set by the amplifier 15 and a relay 28 is switched on, thereby the cooling operation being started. On the contrary, when the indoor temperature becomes lower than the set temperature, the cooling operation is stopped. In the case when a relay 22 is operated by the output of an amplifier 13, a voltage V2 is determined by resistances 9 and 10 irrespective of the output of the amplifier 14.
