twin so would expect one to run? both indoor fans operate and no flashing lights..

[Tayters]

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.

[r.bartlett]

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

Flashing lights on outdoor PCB. 7 times is abnormal thermistor on those models
