  • Page 5 To Install Thermostat (continued) 2. To remove cover, insert and twist a coin or screwdriver in the slots on the sides of the thermostat. 3. Put thermostat base against the wall where you plan to mount it (Be sure wires will feed through 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 battery holder. 15. Replace cover on thermostat by snapping it in place. 16. Turn on power to the system at the main service panel.
