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

  To Remove Existing 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.

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.

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. Insert 2 “AAA” batteries into battery holder. Orient them in the proper direction.
13. Turn on power to the system at the main service panel.
14. Configure thermostat to match the type of system you have.
15. Replace cover on thermostat by snapping it in place.
16. Test thermostat operation as described in “Testing the Thermostat”).

Installing and Changing Batteries

If you

r LCD is blank, or displaying 

LO BAT

, the batteries are not installed or need to be changed. We 

suggest you change the batteries at least once a year, or whenever the 

LO BAT 

warning displays. 

Remove the cover, and install the two “AAA” alkaline batteries into the battery compartment. Proper 
battery installation is important! Make sure the positive ends of the batteries match the positive 
terminals in the battery compartment. 
Batteries will provide power to maintain the clock during a power loss.
