Wire Labeling (Continued)

After labeling wires, disconnect them from the existing thermostat terminals.

Remove existing wallplate. To make sure wires do not fall back into wall opening, you may want to tape them to the wall.

If hole in wall is larger than necessary for wires, seal this hole with insulating material so that no hot or cold air can enter the back of the thermostat from the wall. This air could cause a false thermostat reading.

NOTE: Do not connect a “Common” wire (sometimes labeled “C”) to any terminal on this thermostat. Tape up the wire and do not use. This wire provides electricity to non- battery powered thermostats.

Mount Wallplate and Thermostat

Remove the wallplate from your thermostat by pressing the release tab on the bottom of the thermostat. See Figure 2.
