2.2 Installing Your New Thermostat
2.2 Installing Your New Thermostat cont.
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 OFF position.
3. Place fan control switch on front of thermostat to 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.

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 for use on low voltage 24 Volt AC multi-stage systems
with up to two stages of heating and one stage of cooling and requires a transformer
common wire for proper installation. This thermostat is not for use on single stage
heating or cooling systems.

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.
WARNING!
Read BEFORE Testing
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.
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. The cooling system should stop within a few seconds.
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.
• 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 & may cause personal injury.
• This thermostat includes an automatic compressor protection feature to avoid potential
damage to the system from short cycling. This thermostat automatically provides a
5-minute delay after turning off the cooling output to protect the compressor.

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 fingers, 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 fingers, gently flip the switch towards the HG (gas) or HE (Elec) selection
which indicates the low voltage heating system the thermostat will control.
18. 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.
19. Restore system power so you can test installation.
