Installed Nest Thermostat and Electronic Air Cleaner Doesn't Have Power

Community Member

I installed my 2nd generation (I think-it's used, could be 3rd gen) learning thermostat, and everything works, except my electrostatic air cleaner won't turn on. I am attaching pictures from the wiring of the previous Honeywell thermostat, and my current Nest. I have tried using the Rh and Rc wires, and they both have the same result - everything works except the air filter. I also have an Ultraviolet Air Cleaner attached, which is working fine.
