INSTAllATION

INSTAllATION lOCATION RECOMMENDATIONS

Thermostat shouꢀd ꢂe mounted:

REMOTE TEMpERATURE SENSOR (OpTIONAl)

Do not mount thermostat:

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

•

On an interior wall, in a frequently occupied space.

Approximately 5‘ above floor.

• Behind doors, in corners or other dead air spaces.

• In direct sunlight, near lighting fixtures, or other

appliances that give off heat

At least 18” from outside wall.

Remote temꢃerature sensor shouꢀd ꢂe mounted:

On an interior wall, in a frequently occupied space.

Do not mount remote sensor:

•

On an outside or unconditioned area wall.

Thermostat can be mounted to a vertical junction box.

•

• Behind doors, in corners or other dead air spaces.

In the flow of a supply register, in stairwells, or near

outside doors

• Approximately 5‘ above floor.

• At least 18” from outside wall.

• In direct sunlight, near lighting fixtures, or other

appliances that give off heat

•

On a wall with concealed pipes or ductwork.

•

On an outside or unconditioned area wall.

•

Using less than 300’ of wire.

OUTDOOR TEMpERATURE SENSOR (INClUDED)

• In the flow of a supply register, in stairwells, or near

outside doors

Outdoor temperature can be measured by attaching the included 8052 sensor to the S1 and S2 terminals The

outdoor sensor must be enabled in the installer setup menu

•

On a wall with concealed pipes or ductwork.

Near 120 VAC lines.

Heat ꢃumꢃ modeꢀs can use the outdoor temꢃerature to eꢄꢄectiveꢀy utiꢀize the heat ꢃumꢃ:

•

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

Indoor Air Quaꢀity ꢄunctions can use the outdoor temꢃerature sensor to:

•

Control humidification setpoint based on outdoor temperature to prevent condensation

Lock out humidification for temperatures over 60°F or below -30°F.

Lock out ventilation based on high and/or low outdoor temperatures.

Display outdoor temperature on thermostat.

On side of building out of direct sunlight (north side recommended).

Above snow line.

Remove the rear mounting plate from the thermostat

Pull wires through the opening on the back of the

thermostat

At least 3’ away from exhaust vents and condensing lines.

Using less than 300’ of wire.

Position and level the mounting plate of the thermostat

on wall and mark the hole locations with a pencil

Do not route wires along 120 VAC lines.

. Drill 1/4” holes and insert supplied anchors

. Place mounting plate over anchors, insert and tighten

screws

Seal wire entry holes to prevent drafts affecting
