    Ah, was thinking more the outdoor unit.
    The VRF's need the compressor probe on top to be over 40°C I think it is before they run, not sure on the multi set up though.

    As per Tayters, Might be no harm to check the sensor on compressor, if it's faulty then no run, no fault shows either if i remember.
    Mostly found in the southern part of this green and pleasant land.

    ok I'll check.. bit poor show for them not to integrate a sensor fault in the fault circuit..
