Had a look at this three phase two speed system as it wasn’t cooling.
It was bringing the condenser fan on but the compressor didn’t run in either speed. I traced the fault to the compressor interlock timer which is a start delay timer in the feed to the contactor coils via the hi/lo speed relay, which is the 8 pin one in the vid.
Took me a bit of time to get my head round the 24v ac control circuit as most things i work on have a 240v & N control circuit!
Luckily i had a Supco timer on the van that would work on 24v so i fitted and tested that.
