REMOVE OLD THERMOSTAT
Shut off electricity at main fuse or circuit breaker box until installation is complete AND the new thermostat is configured properly.
Remove the front cover of the old thermo- stat. With wires still attached, remove wall plate from the wall.
Identify each wire attached to the thermo-
stat using one of the labels enclosed with the new thermostat.
Disconnect the wires from the old thermostat one at a time. DO NOT let the wires fall back into the wall.
Install the new thermostat using the follow- ing procedures.
ATTACH BASE TO WALL
Remove packing material from the thermostat. Place fingers of one hand on the center top and bottom portion of the thermostat. Grasp the base in the other hand on top and bottom center and gently pull straight out. Forcing or prying on the thermostat will cause damage to the unit.
Place the base over the hole in the wall where the wires come out and mark mount- ing hole locations using the base as a template. Drill 3⁄16” pilot holes, and install screw anchors in the wall.
Run wires through hole in base and attach base to wall (see fig. 1).
Insert the labeled wires into the appropriate terminals on the base and tighten the terminal screws.
