the NEC code.
WARNING
!
INSTALLATION 
Remove Old Thermostat
A standard heat/cool thermostat consists of three basic parts:
1.  The cover, which may be either a snap-on or hinge type.
2.  The base, which is removed by loosening all captive  
screws.
3.  The switching subbase, which is removed by unscrewing
 
the mounting screws that hold it on the wall or adapter
 plate. 
Before removing wires from old thermostat, label 
each wire with the terminal designation from which it  
was attached. Disconnect the wires from the old thermo- 
stat one at a time. 
Do not let wires fall back into the wall.
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 snug-
 
ly, use plastic screw anchors to secure the base.
4.  Fasten base snugly to wall using mounting holes shown
 
in Figure 2 and two mounting screws. Leveling is for
 
appearance only and will not affect thermostat operation.
5.  Connect wires to terminal block on base.
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.
SS/HP Switch
(Conventional or Heat Pump Selection)
The SS/HP switch is factory set to the SS position. In this posi-
tion, thermostat is configured as conventional single stage. If 
you have a single stage heat pump system, switch SS/HP to 
HP position (see figure 2).
Gas/Elec Switch (Fan Option)
The GAS/ELEC switch is factory set to the GAS position. In 
this position, the thermostat will not power the circulator fan on 
a call for heat, but will power the circulator on a call for cool.
If your system requires that the thermostat power the circula-
tor fan on a call for heat, this switch should be set to the ELEC 
position. Typically, gas and oil heating systems do not require 
the thermostat to power the circulator fan during a call for heat. 
If your heat is gas or oil, the switch should be set to the GAS 
position.
When the thermostat is configured for Heat Pump, the thermo-
stat will always power the circulator fan on a call for heat in the 
HEAT mode.
Batteries
2 "AA" alkaline batteries are included in the thermostat. To in-
stall the batteries, pull the battery door as shown by the arrow 
and lift open. Using the polarity indicated inside the battery 
door, insert the batteries. To close the battery door, swing the 
door down while pulling in the direction of arrow. Once fully 
down, snap the door back into position. 
To replace the batteries, set system to OFF, following the 
instructions above.
Thermostat can be powered by system AC power or Battery. 
If 
 is displayed, the thermostat is battery powered. If
 
 is not displayed, thermostat is system powered with 
optional battery back-up. When battery power remaining is 
approximately half, the 
 will be displayed. When 
"Change 
is displayed, install fresh “AA” alkaline batteries imme-
diately. For best results, replace all batteries with a premium 
brand alkaline battery such as Duracell
®
 or Energizer
®
. We 
recommend replacing batteries every 2 years. If the home 
is going to be unoccupied for an extended period (over 3 
months) and 
 is displayed, the batteries should be re-
placed before leaving. When less than two months of battery 
life remain, the setpoint temperature will offset by 10 degrees 
(10 degrees cooler in Heat mode / 10 degrees warmer in 
Cool mode). If offset occurs, the normal setpoint can be 
manually reset with 
 or 
. Another offset will occur 
within two days if batteries are not replaced.
