Help with buying a programmable thermostat to replace a White-Rodgers manual thermostat?
I currently have a White-Rodgers Heat Pump Thermostat with a mercury bulb. I want to replace it with a programmable thermostat - preferable 7 day. The thing that is throwing me off when trying to find a replacement is the wiring diagrams don't match.
When picking out a thermostat make sure it says single cooling and 2 stage heating. The two stages are 1 for the heat pump and 1 for the electric heat strips. Here is a site that can help.
