Important Safety Information
WARNING!
:
Always turn off power at the main power supply before installing, cleaning,
or removing thermostat.
• This thermostat is for 24 VAC applications only; do not use on voltages over 30 VAC
• Do not short across terminals of gas valve or system control to test operation; this will damage your
thermostat and void your warranty
• All wiring must conform to local and national electrical and building codes
• Do not use air conditioning when the outdoor temperature is below 50 degrees; this can damage
your A/C system and cause personal injuries
• Use this thermostat only as described in this manual

ELECTRICAL SHOCK HAZARD
– Turn off power at the main service panel by removing
the fuse or switching the appropriate circuit breaker to the OFF position before
removing the existing thermostat.
1. Turn off power to the heating and cooling system by removing the fuse or switching the appropriate
circuit breaker off.
2. Remove cover of old thermostat. This should expose the wires.
3. Label the existing wires with the enclosed wire labels before removing wires.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.
6. Refer to the following section for instructions on how to install this thermostat.

To Install Thermostat
ELECTRICAL SHOCK HAZARD
– Turn off power at the main service panel by removing
the fuse or switching the appropriate circuit breaker to the OFF position before
removing the existing thermostat.
IMPORTANT:
Thermostat installation must conform to local and national building and
electrical codes and ordinances.
Note:
Mount the thermostat about five feet above the floor. Do not mount the thermostat on an
outside wall, in direct sunlight, behind a door, or in an area affected by a vent or duct.
1. Turn off power to the heating and cooling system by removing the fuse or switching the
appropriate circuit breaker off.
2. To remove cover, pull gently at the seam at the top.
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 slit in thermal
intrusion barrier and into wire opening.
9. Use supplied screws to mount thermostat base to wall.
10. Insert stripped, labeled wires in matching wire terminals.
CAUTION!:
Be sure exposed portion of wires does not touch other wires.
11. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the
proper terminal.
12. Place gas/elec jumper in correct position.
gas
= gas/oil systems
elec
= electric heat or heat pump systems
13. Remove RC/RH jumper for 2-transformer systems.
14. Non-heat pump jumper must be in Non-HP unless the system is a heat pump.
15. Insert 2 “AAA” batteries into battery holder. Orient them in the proper direction.
16. Turn on power to the system at the main service panel.
17. Configure thermostat (see Configuration Mode Settings) to match the type of system you have.
18. Replace cover on thermostat by snapping it in place.
19. Test thermostat operation as described in “Testing the Thermostat”.
