After 5 minutes, timer then closes the control circuit and compressor is free to start when required, so long as pressure switches are also closed.

    Re: High and low pressure switch in air-cond

    How do i block the attempt by the thermostat to start the compressor again, cause in the diagram if the thermostat is off and on back it will attempt start the compressor within 5 minute.
