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.
WI-FI SETUP
For detailed instructions for connecting the thermostat to a Wi-Fi network and registering it to an Aprilaire account,
refer to the Wi-Fi Quick Start Guide included in the box.

OUTDOOR TEMPERATURE SENSOR (OPTIONAL)
Outdoor temperature can be measured by attaching an
8052 sensor to the S1 and S2 terminals. System setting
#15 (Outdoor Sensor) is used to enable sensor.
Heat pump applications 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 to provide heating.
• 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.

• Install on side of building out of direct sunlight
(north side recommended).
• Mount above snow line.
• Mount at least 3’ away from exhaust vents and
condensing lines.
• Maximum wire length is 300’.
• Do not route wires along 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 rear
mounting plate.
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.
INSTALLATION
POWER & RESET OPTIONS
The thermostat is powered from 24VAC. In the case of power loss the thermostat will maintain the clock for 24
hours. The thermostat has a memory backup that saves the thermostat settings in case of power interruption.
The reset button located under the cover on the front of the thermostat can be used to reset the thermostat to
factory defaults. The system settings will also be set to default.

• 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.

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.
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).
HEATING SYSTEM DOES NOT RESPOND
(“HEATING” APPEARS ON SCREEN)
• Check for 24 VAC 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 24 VAC between the heat terminal (W)
and the transformer common. If 24 VAC 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.
TROUBLESHOOTING
COOLING SYSTEM DOES NOT RESPOND
(“COOLING” APPEARS ON SCREEN)
• Check for 24 VAC 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 24 VAC between the cooling terminal (Y)
and the transformer common. If 24 VAC 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 #07 (Fan Control), to make
sure the fan control is properly set to match the type
of system (see page 12).
HEAT PUMP ISSUES COOL AIR IN HEAT MODE,
OR WARM AIR IN COOL MODE
• Check System Setting #03 (Reversing Valve), to make
sure it is properly configured for your system (see
page 11).
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 10).
• 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 10).
“HEATING” IS NOT DISPLAYED
• Change the System Mode to Heat, and set
the temperature level above the current room
temperature.
“COOLING” IS NOT DISPLAYED
• Change the System Mode to Cool, and set
the temperature level below the current room
temperature.
