Before removing wires from old thermostat, mark wires for 
terminal identifi cation so the proper connections will be made 
to the 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 snug-

 

ly, 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 fi re re-
 

sistant material (such as fi berglass insulation) to prevent

 

drafts from affecting thermostat operation.

7.  Carefully line the thermostat up with the base and snap
 into 

place.

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.

Refer to equipment manufacturers' instructions for specifi c 
system wiring information. After wiring, see CONFIGURA-
TION section for proper thermostat confi guration.

Wiring diagrams shown are for typical systems and describe 
the thermostat terminal functions.

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

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 fol-
lowing 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.
