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 resis-
tant 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 .
