We replaced our old furnace with Rheem Prestige Series: Up to 96% AFUE Modulating ECM Motor furnace. Right now we have Honeywell RTH 850 programmable thermostat from Home Depot connected by two wires to the new furnace.
Please tell me what kind of thermostat we should buy to get the best performance of our new furnace.
We do not have any additional heating/cooling system at home no heat pump, no air conditioners.
Technician who install our furnace was not able to recommend us anything.
Thank You in advance,
