I had asked a while back but can't find the posting. In the R1 bay in conjunction with the 120v compressor well switch is a regulator. Seems like its a pressure relief regulator. Does anyone know what the correct setting would be?
The purpose of that regulator is to limit the pressure the 120V pump can generate when the HWH system powers the compressor by bypassing the well pump switch. A new Thomas compressor is capable of 150 psi which will explode an air bag. You don’t want to find this out the way I did.
