Re: Mechanical Relay Quality
Post #6 says you measured "0.67A up to 1A then back down" and now you're saying 32mA ???
I looked at Heil ICP Tempstar PA5536AKA4/PYPA36GA4 heat pump, from your picture. It looks just like an air conditioner but has a reversing valve to pump heat into the home and there's some optional electric heater package.
Power transformer is 24VAC 40VA. Based on pictures, you can figure out the schematic of the Heil control board 1087562/Honeywell 1084-83-100A, if I'm right about the one in your outdoor unit.
The thermostat inputs are low current going to a PIC MCU. There is no usual 24VAC inductive loads the thermostat relays would be seeing, like contactors etc.
So either your wiring is wrong and you are crowbarring something or this is a massive goosechase due to a cheap crappy Songle relay.
