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 re-
sistant 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 premi-
um brand "AA" alkaline battery such as Duracell®or Ener-
gizer®. If the home is going to be unoccupied for an extended
period (over 3 months) and is displayed, the batteries
should be replaced before leaving.
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.
WARNING
!
Thermostat installation and all components of the
control system shall conform to Class II circuits per
the NEC code.

Thermostat Power Method Switch Position/Description
Battery Powered, no 24
Volt system power available.
Switches "On", thermostat
runs on batteries.
Hardwired with Battery
Back-up, for 24 Volt systems
with common connection from
transformer to "C" terminal
on thermostat.
Switches "On", thermostat
runs on power directly from
transformer with battery back-
up.
*Battery Powered with
Power Stealing Assist,
for 24 Volt systems with no
common connection from
transformer to "C" terminal on
thermostat.
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.
