INSTALLATION
INSTALLATION LOCATION RECOMMENDATIONS
Thermostat should be mounted:
• On an interior wall, in a frequently occupied space.
• Approximately 5 feet above oor.
• 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 xtures, or other appliances that give off heat.
• On an outside or unconditioned area wall.
• In the ow of a supply register, in stairwells, or near outside doors.
• On a wall with concealed pipes or ductwork.
32

OUTDOOR TEMPERATURE SENSOR (INCLUDED)
Outdoor temperature can be measured by attaching the included 8052 sensor to the T1 and T2
terminals. The outdoor sensor must be enabled in the installer setup menu.
Heat pump models can use the outdoor temperature to effectively utilize the heat pump:
• When the outdoor temperature is lower 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.
Indoor Air Quality functions can use the outdoor temperature sensor to:
• Control humidication set point based on outdoor temperature to prevent condensation.
• Lock out ventilation based on high and/or low outdoor temperatures.
• Display outdoor temperature on thermostat.
Outdoor temperature sensor should be mounted:
• On side of building out of direct sunlight (north side recommended).
• Above snow line.
• At least 3 feet away from exhaust vents and condensing lines.
• Using less than 300 feet of wire.
• Do not route wires along 120 VAC lines.

REMOTE TEMPERATURE SENSOR (OPTIONAL)
A remote temperature sensor can be used for control if the thermostat is to be mounted in a
concealed location or a remote sensor can be averaged with the thermostat sensor to control
a large space. An 8051 ush 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 set-up menu, and once enabled will override or be averaged
with the thermostat’s internal temperature sensor, based on the setting.
Remote temperature sensor should be mounted:
• On an interior wall, in a frequently occupied space.
• Approximately 5 feet above oor.
• At least 18” from outside wall.
• Using less than 300 feet of wire.
Do not mount remote sensor:
• Behind doors, in corners or other dead air spaces.
• In direct sunlight, near lighting xtures, or other appliances that give off heat.
• On an outside or unconditioned area wall.
• In the ow of a supply register, in stairwells, or near outside doors.
• On a wall with concealed pipes or ductwork.
• Near 120 VAC lines.

WIRELESS SENSORS
This thermostat is compatible with the following AprilAire wireless sensors:
• Model Z10IDT Indoor Temperature and Humidity Sensor
Up to eight of these sensors can be connected to the thermostat. Connected sensors will
automatically be averaged, or individual sensors can be selected for scheduled events.
• Model Z10ODT Outdoor Temperature and Humidity Sensor
One sensor can be connected to the thermostat.
The wireless sensor settings can be found under the thermostats’ installer settings. See the
sensors instruction manual for mounting and connecting details.
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. Insert and tighten supplied self-
drilling 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 AND RESET OPTIONS
The thermostat is powered from 24VAC. In the case of power loss, the thermostat will maintain
the clock for 2 hours. The thermostat has a memory backup that saves the thermostat settings
in case of power interruption. The thermostat can be set back to factory defaults from the
installer settings menu. See Installer System Settings section for details.
The factory reset does not clear thermostat account information from the AprilAire Wi-Fi
Thermostat App. To clear this information, remove the thermostat from the app or use the
unregister option from the thermostat’s Wi-Fi settings.
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.
