路。 In an air conditioner operation circuit, a signal from the operation unit is input to a microprocessor, and based on this signal, the microprocessor controls the operation of the compressor, blower, etc. via a relay. When the equipment is operating normally, it turns ON, and when the equipment is operating abnormally, it turns OFF.
A first transistor that is in the F state, a second transistor that is in the ON state when the first transistor is in the ON state, and when the contacts are connected, the second transistor can bypass the microprocessor and energize the relay. A forced operation circuit for an air conditioner, comprising: a switch connected to the air conditioner.
