INSTALLATION
WARNING
Thermostat installation and all components of the
control system shall conform to Class II circuits per
the NEC code.
Remove Old Thermostat
Before removing wires from old thermostat, mark wires for
terminal identification so the proper connections will be made
to the new thermostat.
Installing New Thermostat
1. Pull the thermostat body off the thermostat base. Forcing
or prying on the thermostat will cause damage to the unit.
2. Place base over hole in wall and mark mounting hole
locations on wall using base as a template.
3. Move base out of the way. Drill mounting holes. If you
are using existing mounting holes and the holes drilled
are too large and do not allow you to tighten base snugly,
use plastic screw anchors to secure the base.
4. Fasten base snugly to wall using mounting holes shown
in Figure 1 and two mounting screws. Leveling is for
appearance only and will not affect thermostat operation.
5. Connect wires to terminal block on base using appropriate
wiring schematic.
6. Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent
drafts from affecting thermostat operation.
7. Carefully line the thermostat up with the base and snap
into place.
Battery Location
2 "AA" alkaline batteries are included in the thermostat at the
factory with a battery tag to prevent power drainage. Remove
the battery tag to engage the batteries.
To replace batteries, set system to OFF, remove thermostat
from wall and install the batteries in the rear along the top
of the thermostat (see Figure 1). For best results, use a
premium brand "AA" alkaline battery such as Duracell
Energizer

Power Stealing Switches
The Power Stealing Switches (Fig. 1) should be left in the
"On" position for most systems. The information in the
following table details the thermostat power method and
switch options.

Switches "On", thermostat
runs on power directly from

Switches "On", thermostat
runs on batteries and
supplemental power drawn
through the heat or cool circuit.
*Power Stealing Assist is very reliable to increase battery life,
but on a small number of heating or cooling systems with high
impedance electronic modules you may observe one of the
following conditions:
1. The furnace draft inducer motor may run with no call for
heat.
2. The furnace fan may turn on with no call for heat or may
not turn off.
3. The furnace may not turn off when the call for heat ends.
4. The air conditioner may not turn off when the call for cool
ends.
If the Power Stealing Assist method is not compatible with
your system, place the Power Stealing Switches to "Off". This
cancels Power Stealing Assist, operates the thermostat on
batteries and corrects the condition.

Dehumidification wiring without an electronically controlled variable speed blower system for
single stage compressor system only.
If you have a single stage compressor system see the diagram below. A relay (customer provided) should be installed
as shown in Fig 7 to switch the fan speed to the next lower
speed on a call for dehumidification from the thermostat. The
reduction in air flow allows the coil to remove more humidity
from the air. The relay should be rated for blower motor load.
Since this configuration reduces the air flow in cooling, the

recommended. The CAFC prevents the air conditioning coil
from freezing due to low air flow, dirty filters, low refrigerant

the evaporator coil as possible and breaks the compressor
circuit when the suction line drops below 38 °F and re-make
