A standard heat/cool thermostat consists of three basic parts:
1. The cover, which may be either a snap-on or hinge type.
2. The base, which is removed by loosening all captive

screws.

3. The switching subbase, which is removed by unscrewing

the mounting screws that hold it on the wall or adapter
plate. Before removing wires from old thermostat,

Remove Old Thermostat

Locate the thermostat/sensor about 5 ft. above floor level on
an interior wall in an area that represents the average room
temperature.

Do not mount directly on or near HVAC equipment or other
sources of electrical noise.

Avoid locations close to windows or near adjoining outside
walls, doors leading outside, areas close to air registers or
their direct air flow or areas with poor circulation like alcoves.
Avoid locating the sensor on a concrete wall, junction box or
metal plate. Make sure there are no electrical wires, metal,
pipes or duct work in the part of the wall chosen for the
sensor location.

installation in unconditioned space.

Guidelines for Thermostat/Sensor Locations

1. Remove the packing material from the thermostat and

sensor.

2. Pull the front covers of the thermostat and sensor straight

off the bases. Forcing or prying will cause damage to the
controls.

3. Using the thermostat and sensor bases as templates,

place them on the selected wall locations and mark the
location of all mounting holes (Figure 1 and 3), and the
hole for the thermostat antenna wire illustrated in Figure 2.

4. Move bases out of the way and drill the holes. If mounting

holes drilled are too large and do not allow you to tighten
base snugly, use the plastic screw anchors (provided) for
secure mounting.

5. Make sure the remote communication receiver is plugged

in properly to the thermostat and that the antenna wire is
routed through the thermostat subbase as shown in
Figure 2.

6. Fasten bases loosely to wall, using two mounting screws

for each. Place a level against bottom of base (leveling is
for appearance only and will not affect sensor operation)
and then tighten screws.

7. In the thermostat location, push excess wire into wall and

plug hole with a fire resistant material (such as fiberglass
insulation) to prevent drafts from affecting the thermostat
operation.

8. Remove the battery tags in both the thermostat and

sensor and replace the covers by lining them up with the
base and pressing until they snap into place.

Figure 3 – Remote sensor base

The thermostat requires 2 "AA" alkaline batteries and the
sensor requires 2 "AAA" alkaline batteries. Batteries are
included at the factory with a battery tag to prevent power
drainage. The battery tag must be removed to engage the
batteries. For best results, replace batteries once a year with
new premium brand alkaline batteries such as Duracell

Energizer

Battery Location

The ELEC/GAS switch is factory set to the ELEC position. In
this position, the thermostat will power the circulator fan on a
call for heat. Electric heat systems may require the switch to
be in the ELEC position.

If your system does not require that the thermostat power the
circulator fan, this switch should be set to the GAS position.
Typically, gas and oil heating systems do not require the
thermostat to power the circulator fan during a call for heat. If
your heat is gas or oil, the switch should be set to the GAS
position.

When the thermostat is configured for Heat Pump, the
thermostat will always power the circulator fan on a call for
heat in the HEAT mode. The ELEC/GAS switch must be set
to match the type of Auxiliary heat your system uses for
proper operation in the EMERgency mode.
