I have a Carrier 50LJQ004 heat pump and I'm trying to correct the wiring that was done when a Honeywell Vision Pro 8000 thermostat was installed. When the heating company installed the thermostat they configured it as a conventional (not heat pump) system to get it to work halfway right. System will not work correctly when thermostat is programed for a heat pump. I believe issue is that this model heat pump does not have a separate input for the reversing valve. I believe to make this thermostat work correctly with my heat pump I will need to add a relay, something like below. Just trying to get a confirmation on the correct wiring.
