Abstract

PURPOSE: :To cause an indicator lamp to make an indication different from that in the operation of the air conditioner when the air conditioner cannot operate even if a temperature detector detects the reaching to a set temperature.
CONSTITUTION: A periodical signal is generated by an oscillator OSC and supplied to an AND circuit AND-S. The AND of the periodical signal with the output of the temperature detector TD is taken. Thereby, an intermittent signal is produced and supplied to an OR circuit OR. The OR circit superposes the output of an AND circuit AND on the intermittent signal. The superposed signal is applied to the indicator lamp L. When the temperature detector TD performs detecting operation and a delaying timer T generates no output, the AND circuit AND-S supplies the intermittent signal to the OR circuit OR and the AND circuit AND generates no output. Therefore, only the intermittent signal is supplied to the OR circuit OR from the AND circuit AND-S, and the indicator lamp L is intermittently lighted on. When the delaying timer T produces an output, the indicator lamp L is continuously lighted on.
