Done. Only Bronze but hope it helps.
That seems so weird. I guess it seemed weird to you too. I don't know the heat pump control wiring intimately, but it seems like there must be 24vac some place in the heat pump that is only active during a home a/c cooling cycle. It also makes me wonder if somehow the internal FPH controller wiring has a mistake. But I'm also guessing you went through all that with great care. Of course your solution is cool, just that one would hope that extra relay would not be necessary, therefore not necessary to ever power off the FPH controller.I also had to wire in a relay to disconnect power to the hotspot because my heat pump has constant 24vac when the system is in AC mode. The control panel will remain powered on after the call for cooling is complete. I guess the 24vac from the sense wire for the reversing valve back feeds the controller.
The white plugs look like pump drain plugs.The black one is your heater drain plug, providing you have a heater.![]()
