It does this in both compressor examples as well, not just my code.
If you have wired the compressor correctly, it is powered via a spike (powered by a dedicated 20A circuit breaker from the power distribution board) and the spike's fuse has been replaced by a 20A circuit breaker IAW <R60> part F.

It is possible that

1. One of the two circuit breakers as bad.
2. The pressure switch has a bad connection somewhere.
3. The current draw from the compresser is too high (bad compressor or shorted wiring).

I really do not think that could be a software issue but I'll defer that issue to others.

Regards,

Mike
