the wire opening in the base of the thermostat).

4. Mark the placement of the mounting holes.

5. Set thermostat base and cover away from working area.

6. Using a 3/16” drill bit, drill holes in the places you have marked for mounting.

7. Use a hammer to tap supplied anchors in mounting holes.

8. Align thermostat base with mounting holes and feed the control wires through wire opening.

9. Use supplied screws to mount thermostat base to wall.

10. Insert stripped, labeled wires in matching wire terminals. See “Wiring Diagrams” section of this

manual (Pages 4-7).

CAUTION!

:

Be sure exposed portion of wires does not touch other wires.

11. Tighten screws on terminal block. Gently tug wire to be sure of proper connection. Double check

that each wire is connected to the proper terminal.

12. Seal hole for wires behind thermostat with non-flammable insulation or putty.

13. Set Gas/Electric switch:

• Set to Gas for oil or gas systems

• Set to Electric for heat pumps or electric heat systems

14. Insert two fresh “AA” alkaline batteries into thermostat; oriented in the direction shown on the
