CAUTION: Do not remove any wiring from existing thermostat before reading
the instructions carefully. Wires must be labeled prior to removal.
IMPORTANT! Turn off the power to the furnace at the main power panel or

Remove existing thermostat cover and thermostat. See Figure 1. Some thermostats
will have screws or other locking devices that must rst be removed. Once the

If wires are not visible, they may be connected to the back of the wallplate. Again,
look for screws, tabs, etc. Some models have doors that open to expose wires

Wiring Documentation
Use table A. to write down your wire colors and the letter designations on the old
thermostat. This will allow you to keep a record of your old thermostat’s wiring
conguration should you need to refer to it at a later time.
This will also help our Technical Support Department determine your system type
and proper wiring, should you need to contact them. Wire color does not indicate
the function of the wire, this is being used only to help determine which wire has
what letter designation.
