ABSTRACT:
The timer circuit of the present invention comprises a comparator, which, in the example of the air conditioner, compares the room temperature measured by a thermistor with a predetermined value and charges the timer capacitor of the timer circuit when its output is in ON state, and makes the capacitor discharge when its output becomes in OFF state; thereby the timer circuit can produce the first set time, for example, by the abovementioned discharging time, in this first set time a compressor circuit being made OFF for prevention of overloading due to a too-early restarting, and furthermore, with utilizing the same timer circuit with a modified predetermined value of the comparator thereby producing subsequent cycles of charging and discharging and accumulating a predetermined number of repetition of the cycles, a desired longer time for the second time can be produced.
