Move the Function switch on the thermostat to Off.
Remove the cover by inserting and twisting a coin or screwdriver in the slots on the top of the thermostat.
Put the thermostat base against the wall where you plan to mount it. Make sure wires will feed through the wire opening in the base of the thermostat.
With the base level, mark the placement of the mounting holes.
Set the thermostat base and cover away from the working area.
Using a 3/16 drill bit, drill holes in the locations you have marked for mounting.
Use a hammer to tap supplied anchors in mounting holes.
Align the thermostat base with mounting holes and feed the control wires through the wire opening.
Seal holes for wires behind thermostats with non-flammable insulation or putty, or use a wall plate obtainable from a local hardware or home building store.
Use supplied screws to mount the thermostat base to the wall.
Insert stripped, labeled wires in matching wire terminals by pressing on the corresponding terminal contact. See the “Wiring Diagrams” section of this manual.
CAUTION! Make sure the exposed portion of the wires does not touch other wires.
Gently tug the wire to be sure of the proper connection. Double-check that each wire is connected to the proper terminal.
