Product Usage Instructions

Remove Your Old Thermostat

1. Turn off power at heating/cooling system (or fuse/circuit-breaker panel).
2. Remove cover and thermostat, but leave wallplate with wires attached.

Caution: If your old thermostat contains mercury in a sealed tube, do not place it in the trash. Contact your local waste management authority for recycling and proper disposal instructions.

Note: Count the number of wires coming out of the wall and attached to terminals in your old thermostat. If any of them are attached to a terminal marked C or C1, do not count that wire in your total. If the total (not counting C or C1) is 4 wires or less, proceed to the next page. If you have 5 or more wires, your new thermostat may not be compatible with your system. Stop installation and call 1-800-468-1502 for advice.

Label Wires and Remove Old Wallplate

1. Use a screwdriver to disconnect wires one by one.
2. As you disconnect each wire, wrap it with the label matching the letter on your old thermostat. (Adhesive labels are supplied in your thermostat package.)
3. Remove the old wallplate only after all wires are labeled. Be careful not to let loose wires fall into the wall opening.

Note: Use only letter designations to identify wire types. Ignore wire colors.

Mount Thermostat Base

1. Drill holes at pencil-marked locations (3/16″ holes for drywall, 7/32″ holes for plaster).
2. Use a hammer to tap anchors into holes until flush with the wall.
3. [Optional] Pull wires through cover plate (if needed to cover marks left by your old thermostat).
4. Pull wires through thermostat base and insert screws. Check level if desired, then tighten screws.

Connect Wires

1. Match each labeled wire with the same letter on the terminal.
2. Use a screwdriver to loosen screw terminals, wrap bare wire securely around terminals, then tighten screws.
3. Push any excess wire back into the wall opening.

Note: If labels do not match letters on the thermostat, refer to the table provided in the manual for proper connection instructions.
