I got my HestiaPi about a week ago, and have been working on installing it this morning, but have run into a snag that can hopefully be resolved by editing the OpenHab rules:
On my HVAC system (Lennox single stage heat pump) the yellow wire energizes the outdoor unit, and an orange wire activates the reversing valve to switch the system to cool.
Connected, my terminal block looks like this:
Black Red Yellow Orange Green White
Heat seems to work fine, the system energizes yellow and green, but here’s my question: To get cool I would have to energize both the heat and cool pins (in my case, the yellow and orange wires). I’m sure this is possible with a change in the OpenHab logic, but I’ve only been working with it for 24 hours or so, and haven’t yet figured out where to make that change.
Any pointers would be greatly appreciated.
