INSTALLATION
Replacing Existing Thermostat
2.1
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.
Installing Your New Thermostat
2.2
NOTE:
If you are installing this thermostat in a new installation be sure to locate
the thermostat 4 to 5 feet above the floor in accordance with applicable building
codes. Make sure to install the thermostat in a location that provides good airflow
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 finger, gently flip 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 fired 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 finger, gently flip 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
configures the thermostat for normal (NORM NON-HP) heating and cooling systems
or heat pump (HP) systems.

INSTALLATION
19. Using your finger, gently flip the switch towards the NORM NON-HP or HP selection
which indicates the low voltage heating system the thermostat will control.
20. Attach front body of thermostat to sub-base of thermostat, being careful to align the
terminal pins on the front body with the terminal block on the sub-base.
21. Open front thermostat door and open battery compartment door.
22. Install two new "AA" alkaline batteries into battery compartment. Make sure to locate
the positive (+) ends of the batteries and match them with the positive (+) terminals
located in the battery compartment.
23. Close battery compartment.
24. Restore system power so you can test installation.
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 configurations
prior to programming. Gently press the RESET button on the front of the thermostat using
a paper clip or a small pencil tip.

NEW THERMOSTAT
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.
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.
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.
