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.

This thermostat is designed for 24 VAC power to be hard-
wired via a common connection to the C terminal with battery 
back-up. The thermostat also has the capability to be battery 
powered with the battery power supplemented by Power 
Stealing to extend the battery life. Powered only by the two 
"AA" batteries the expected battery life is about one year. 
With battery power supplemented by the Power Stealing 
circuits the battery life can be extended up to fi ve years. The 
supplemental power is derived from the Heating (W) and/or 
Cooling (Y) circuits. The thermostat will utilize either one or 
both of these circuits to supplement the battery power. The 
thermostat "steals" power from these circuits when the circuit 
is not active (calling for heating or cooling).
The Power Stealing switches are defaulted to the ON position. 
If the thermostat is hardwired with "C" common connection, 
both switches should be moved to the OFF position. If the 
thermostat is battery powered and the heating or cooling sys-
tem does not cycle, indicating the system is not compatible, 
the switch for the circuit, heating or cooling, experiencing the 
incompatibility should be moved to the OFF position.
