INSTALLATION
INSTALLATION LOCATION RECOMMENDATIONS
Thermostat should be mounted:
• On an interior wall, in a frequently occupied space.
• Approximately 5‘ above floor.
• At least 18” from outside wall.
• Thermostat can be mounted to a vertical junction box.
Do not mount thermostat:
• Behind doors, in corners or other dead air spaces.
• In direct sunlight, near lighting fixtures, or other
appliances that give off heat.
• On an outside or unconditioned area wall.
• In the flow of a supply register, in stairwells, or near
outside doors.
• On a wall with concealed pipes or ductwork.
OUTDOOR TEMPERATURE SENSOR (OPTIONAL)
Heat pump models can use the outdoor
temperature to effectively utilize the heat pump:
• When the outdoor temperature is less than the Low
Balance Point, the heat pump will be locked out and
only auxiliary heating will be used.
• When the outdoor temperature is higher than the
High Balance Point, the auxiliary heating will be
locked out and only the heat pump will be used to
provide heating.
Outdoor temperature sensor should be mounted:
• On side of building out of direct sunlight (north side
recommended).
• Above snow line.
• At least 3’ away from exhaust vents and condensing
lines.
• Using less than 300’ of wire.
• Do not route wires along 120 VAC lines.

Outdoor temperature can be measured by attaching an 8052 sensor to the S1 and S2 terminals. The outdoor sensor
must be enabled in the installer setup menu.

REMOTE TEMPERATURE SENSOR (OPTIONAL)
A remote temperature sensor can be used if the thermostat has to be mounted in a concealed location. A 8051 flush
mount or 8053 surface mount remote temperature sensor can be attached to the T1 and T2 terminals and mounted
in a recommended area. The remote sensor must be enabled in the installer setup menu. When the remote sensor is
installed it overrides the internal sensor.
Do not mount remote sensor:
• Behind doors, in corners or other dead air spaces.
• In direct sunlight, near lighting fixtures, or other
appliances that give off heat.
• On an outside or unconditioned area wall.
• In the flow of a supply register, in stairwells, or near
outside doors.
• On a wall with concealed pipes or ductwork.
• Near 120 VAC lines.

THERMOSTAT MOUNTING
1. Remove the rear mounting plate from the thermostat.
2. Pull wires through the opening on the back of the
thermostat.
3. Position and level the mounting plate of the thermostat
on wall and mark the hole locations with a pencil.
4. Drill 1/4” holes and insert supplied anchors
(drywall only).
5. Place mounting plate over anchors, insert and tighten
screws.
6. Seal wire entry holes to prevent drafts affecting
temperature readings.
POWER & RESET OPTIONS
The thermostat is dual power. It can either be AC or battery powered, or both (to provide backup power for the clock).
Batteries are optional if your thermostat was wired to run on AC power when installed.
For heat pump systems the C terminal must be connected to the common of the 24VAC transformer in order for the
system fault and emergency heat indicators to operate.
The thermostat has a memory backup that saves the thermostat settings in case of a power interruption. The system
settings will be retained but the clock will reset after 90 seconds with no battery or AC power.
The reset button located under the battery cover can be used to reset the thermostat to factory defaults. The system
settings will also be reset to default.

WIRING TERMINAL
Wire specifications:
18-24 gauge thermostat wire
Installation notes:
• Ensure power at the HVAC equipment is off.
• Loosen screw terminals, insert stripped wire and
re-tighten.
• Push the excess wire back into the opening and plug
the wall opening to prevent drafts.

In this setting, the heat pump will lock out before the fossil fuel auxiliary heat comes on; eliminating the need for a dual fuel kit. If utilizing
electric auxiliary heat, set to Electric. In this setting, the heat pump and electric auxiliary heat are allowed to run simultaneously.

TROUBLESHOOTING
DISPLAY IS BLANK
• Check circuit breaker and reset if necessary.
• Make sure power switch at heating & cooling
system is on.
• Make sure furnace door is closed securely.
• If thermostat is battery powered, make sure fresh AA
alkaline batteries are correctly installed.
HEATING SYSTEM DOES NOT RESPOND
(“HEATING” APPEARS ON SCREEN)
• Check for 24VAC at the equipment on the secondary
side of the transformer between power and
common. If voltage is not present, check the heating
equipment to find the cause of the problem.
• Check for 24VAC between the heat terminal (W)
and the transformer common. If 24VAC is present,
the thermostat is functional. Check the heating
equipment to find the cause of the problem.
• Check for loose or broken wires between the
thermostat and the heating equipment.
TEMPERATURE SETTINGS DO NOT CHANGE
Make sure heating and cooling temperatures are set to
acceptable ranges:
• Heat: 40° to 90°F (4° to 32°C).
• Cool: 50° to 99°F (10° to 37°C).
COOLING SYSTEM DOES NOT RESPOND
(“COOLING” APPEARS ON SCREEN)
• Check for 24VAC at the equipment on the secondary
side of the transformer between power and
common. If voltage is not present, check the cooling
equipment to find the cause of the problem
• Check for 24VAC between the cooling terminal (Y)
and the transformer common. If 24VAC is present,
the thermostat is functional. Check the cooling
system to find the cause of the problem.
• Check for loose or broken wires between the
thermostat and the cooling equipment.
FAN DOES NOT TURN ON IN A CALL FOR HEAT
• Check System Setting 05 (Fan Control), to make sure
the fan control is properly set to match the type of
system (see page 6).
HEAT PUMP ISSUES COOL AIR IN HEAT MODE,
OR WARM AIR IN COOL MODE
• Check wiring at the terminal block to confirm the
reversing valve is connected to the proper terminal.
O is active in cooling and B is active in heating.
HEAT/COOL BOTH ON AT SAME TIME
• Check SW1 (Equipment Type), to make sure it is set
to match the installed heating/cooling equipment
(see page 5).
• Check to make sure heating and cooling wires are
not shorted together.
HEATING EQUIPMENT IS RUNNING IN COOL
MODE
• Check SW1 (Equipment Type), to make sure it is set
to match the installed heating/cooling equipment
(see page 5).
“HEATING” IS NOT DISPLAYED
• Check Installer System Setting number 01
(Control Setup) is set correctly.
• Change the System Mode to Heat, and set
the temperature level above the current room
temperature.
“COOLING” IS NOT DISPLAYED
• Check Installer System Setting number 01
(Control Setup) is set correctly.
• Change the System Mode to Cool, and set
the temperature level below the current room
temperature.
ERROR CODES
If the thermostat enters an error mode, all outputs are turned off. The thermostat attempts to recover every 10 minutes.
If the error does not clear, use the reset button. This will return all settings back to factory default.
