PUHY-P250YMF-C (r407c) TEST RUN

I'm facing a strange problem A system consiting of 6 ICs a BC and a OC heats only when I impose TEST RUN form SW-3. The pressures during TEST RUN are 56psig/260psig. If I switch the ICs on, the compressor starts but after a while stops eventhough the coils of the ICs are cold. The compressor works for short periods of time and the indication standby doesn't go off. Any sugestions?

Why have you got a BC on a Heat Pump System when you should have a Heat Recovery OC ?
