WARNING!
Important Safety Information
Always turn off power to the air conditioning or heating system prior to installing,
removing, cleaning or servicing thermostat.
Read this manual thoroughly prior to installing, programming or operating

this thermostat.
This thermostat is designed for use with a 24 Volt-AC low voltage single stage

gas, oil or electric heating or cooling systems.
Do not use this thermostat on applications with voltages above 30 Volts AC.
This thermostat requires two (2) properly installed "AA" alkaline batteries to

provide power for the thermostat to properly control the system operation.
Wiring must conform to all building codes and ordinances as required by local and
national code authorities having jurisdiction.
Do not short (or jumper) across terminals on the gas valve or at the heating or

cooling system control board to test the thermostat installation. This could

damage the thermostat and void the warranty.
Do not select COOL mode of operation if the outside temperature is below 50 F
(10 C). This could possibly damage the controlled cooling system and may cause
personal injury.
This thermostat should only be used as described in this manual. Any other use is

not recommended and will void the warranty.

2.1
Replacing Existing Thermostat
1. Always turn off power to the air conditioning or heating system prior to removing
existing thermostat.
2. Remove the cover of your old thermostat and locate the wire terminals. Do not
remove wires from terminals yet.
3. Using small pieces of masking tape, label wires prior to removal from terminals. Use
the chart below to determine the new terminal designations for your new thermostat.

4. After labeling and removing all wires from terminals, unscrew the existing thermostat
sub-base from wall. Make sure to secure wires to prevent them from slipping back
into the hole in the wall.
NOTE:
This thermostat is designed for use with a 24 Volt AC low voltage single
stage gas, oil or electric heating or cooling systems, including single stage heat
pumps. This thermostat can also be used on 250mv to 750mv millivolt heating only
systems. Do not use this thermostat on applications with voltages above 30 Volts AC.
2.2
Installing Your New Thermostat
NOTE:
If you are installing this thermostat in a new installation be sure to locate
the thermostat 4 to 5 feet above the oor in accordance with applicable building
codes. Make sure to install the thermostat in a location that provides good airow
characteristics and avoid areas behind doors, near corners, air vents, direct sunlight
or near any heat generating device. Installation in any of these areas could impact
thermostat performance.
1. Always turn off power to the air conditioning or heating system prior to installing your

new thermostat.
2. Place system switch on front of thermostat to the OFF position.
3. Place fan control switch on front of thermostat to the AUTO position.
4. Remove front of thermostat body from sub-base by pressing release latch on bottom

of front body.
5. Place the thermostat sub-base against wall in the desired thermostat location.
6. Guide thermostat wires through center hole in sub-base. Continue to hold sub-base

against wall.
7. Mark placement of mounting holes as appropriate and drill using a 3/16" drill bit.
8. Gently tap supplied plastic anchors into the holes in the wall.
9. Place the thermostat sub-base against the wall in the desired location, making sure

the mounting holes are aligned as appropriate and the thermostat wires are properly

inserting through opening in middle of sub-base.
10. Fasten the sub-base to wall using supplied screws.
11. Connect wires to quick wiring terminal block as appropriate using the new terminal

designations. Refer to Wiring Diagram section of this manual if required for assistance.
12. Make sure all of the wire connections are secure and are not touching any other

terminal to prevent electrical shorts and potential damage to the thermostat.
13. Turn the front thermostat body over exposing the rear view of the circuit board.
14. Locate the internal F / C switch on the circuit board.
15. Using your nger, gently ip the switch toward the preferred temperature F / C scale.
16. Locate the internal fan option switch, HG (Gas) / HE (Elec) on the circuit board. This

switch controls the heating system fan delay. Select gas for gas or oil red systems.
This will allow the furnace to run for a few seconds before initiating the fan. Select

electric for systems with electric furnace elements that require the fan to come

on immediately.
17. Using your nger, gently ip the switch towards the HG (Gas) or HE (Elec) selection

which indicates the low voltage heating system the thermostat will control.
18. Locate the internal NORM NON-HP / HP switch on the circuit board. This switch

congures the thermostat for normal (NORM NON-HP) heating and cooling systems

or heat pump (HP) systems.
TESTING YOUR
NEW THERMOSTAT

NOTE:
Test your thermostat prior to programming any user settings. Pressing the
RESET button will erase any user entries for time of day, day of week, option settings
and programming if previously programmed. This will return all user settings and
return them to their default values. Remember, this will erase all programs entered by
the user.
WARNING!
Read BEFORE Testing
Do not short (or jumper) across terminals on the gas valve or at the heating or

cooling system control board to test the thermostat installation. This could damage
the thermostat and void the warranty.
Do not select COOL mode of operation if the outside temperature is below
50 F (10 C). This could possibly damage the controlled cooling system and may
cause personal injury.
This thermostat includes an automatic compressor protection feature to avoid

potential damage to the cooling system from short cycling. This thermostat

automatically provides a 5-minute delay after turning off the cooling system output
to protect the compressor. This protection is also present in the heat mode of

operation on single stage heat pump systems to protect the compressor.
INSTALLATION

cont.
NOTE:

If you installed the batteries prior to accomplishing steps 14 through 19, then
you will need to reset the thermostat to register your thermostat switch congurations
prior to programming. Gently press the RESET button on the front of the thermostat using
a paper clip or a small pencil tip.
1. Place the system switch in the HEAT position.
2. Press the button on the keypad until the setpoint temperature setting is a minimum of 3
degrees higher than the current room temperature. The heating system should start within
several seconds. The fan may not turn on immediately due to the heating system built-in

fan delay.
3. Place the system switch in the OFF position. The heating system should stop within several
seconds on normal single stage heating or cooling systems. On single stage heat pump
systems you must wait 5 minutes for the automatic compressor short cycle protection period to
expire, or press the
RESET button to bypass this feature for initial testing purposes. Pressing the

RESET button will erase any user entries for time of day, day of week, option settings and
programming if previously programmed.
4. Place the system switch in the COOL position.
5. Press the button on the keypad until the setpoint temperature is a minimum of 3 degrees
lower than the current room temperature.
6. The cooling system should start within several seconds. Place the system switch in the


OFF position.
7. Place the fan switch in the ON position. The system blower should start.
8. Place the fan switch in the AUTO position. The system blower should stop.
19. Using your nger, gently ip the switch towards the NORM NON-HP or HP sele
