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.  Install 2 "AA" alkaline batteries.
8.  Carefully line the thermostat up with the base and snap
 
into place.
Battery Location
2 "AA" alkaline batteries are included with the thermostat. 
Install the batteries before snapping the thermostat on the 
base. Install the batteries in the rear along the top of the 
thermostat (see Fig. 1). 
To replace batteries, set system to 
OFF and remove 
thermostat from wall. For best results, use a premium brand 
"AA" alkaline battery such as Duracell
®
 or Energizer
®
. 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.
WIRING CONNECTIONS 
Refer to equipment manufacturers' instructions for specific 
system wiring information. After wiring, see CONFIGURA-
TION section for proper thermostat configuration.
Wiring diagrams shown are for typical systems and describe 
the thermostat terminal functions.
WARNING
!
Thermostat installation and all components of the 
control system shall conform to Class II circuits per 
the NEC code.

Power Stealing Switch
The Power Stealing Switches (Fig. 1) should be left in the 
"On" position for most systems. 
Power Stealing Assist is very reliable to increase battery life, 
drawing a small amount of power from the HVAC system. But 
on a small number of heating or cooling systems with high 
impedance electronic modules you may observe one of the 
following conditions to indicate that Power Stealing Assist is 
incompatible: 
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.
