NOTE: Test your thermostat prior to programming any user settings. Pressing the RESET button will erase any user entries
previously programmed. This will erase all user settings and return them to their default values.

1. Place the system switch in the ON position.
2. For heat only thermostats press the button on the keypad until the set point 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.
4. For cool only thermostats press the button on the keypad until the set point temperature is a minimum of 3 degrees lower than the
current room temperature.
5. The cooling system should start within several seconds. Place the system switch in the OFF position. The cooling system should stop
within a few seconds.
6. Place the fan switch in the ON position. The system blower should start.
7. Place the fan switch in the AUTO position. The system blower should stop.
Setting the Temperature Differential
The default settings for the temperature differential is compatible with most systems and applications. The temperature differential is
normally set at time of installation and usually does not require any modification under normal operating conditions. If you feel that your
system is turning on too often, simply follow the instructions below.
cont.
2. Press the or buttons to set the temperature differential to your desired setting of
.5˚, 1˚, or 2˚ F (.2˚, .5˚ or 1˚ C).
1. In normal operating mode, press and hold both the and buttons at the same time for
4 seconds. LCD display will show “SET D1 x˚”, where “x” equals the F˚ / C˚ differential
setting. This is the current temperature differential setting.
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 operate compressor 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.
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 any user settings. Gently press the RESET button on the front of the
thermostat using a paperclip or a small pencil tip.
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 HEAT/COOL switch on the circuit board. This switch configures for heating (HEAT) systems or cooling
( COOL) systems.
15. Using your fingers, gently flip the switch towards the HEAT or COOL selection that indicates the system the thermostat will control.
16. For heat only applications 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 that indicates the low voltage heating system
the thermostat will control.
18. Locate the internal F˚/C˚ switch on the circuit board.
19. Using your finger, gently flip the switch toward the preferred temperature F˚/C˚ scale.
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 battery compartment door.
22. Install two new "AA" alkaline batteries into battery compartment. Be 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:
The temperature differential settings are the same for both the heating and cooling systems.
The default setting is 0.5˚ F (0.25˚ C). The room temperature must change 0.5˚ F (0.25˚ C) from the set point temperature before the
thermostat will initiate the system in heating or cooling.
