INSTALLATION
Thermostat installation and all components of the
control system shall conform to Class II circuits per
the NEC code.
WARNING
!
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 thermostat 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 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.
Batteries
2 “AA” alkaline batteries are included with the thermostat.
To install the batteries, pull the battery door as shown by the
arrow and lift open. Using the polarity indicated inside the bat-
tery 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.
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 approxi-
mately half, the will be displayed. When “Change ”
is displayed, install fresh “AA” alkaline batteries immediately.
For best results, replace all batteries with new premium brand
alkaline batteries such as Duracell® or Energizer®. We recom-
mend 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 replaced 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 batter-
ies are not replaced.

Heat Pump Connections
If you do not have a heat pump system, refer to fi gures 4-6.
Refer to equipment manufacturers’ instructions for specifi c
system wiring information.
You can confi gure the thermostat for use with the following
heat pump systems. Figure 3 – Heat Pump Systems

system; gas or electric backup.
HEAT PUMP TYPE 2 (HP 2). Multi-stage compressor or two
compressor system with gas or electric backup.
After wiring, see INSTALLER CONFIGURATION section for
proper thermostat confi guration.
NOTE: If your system does
not provide an E connection,
jumper W2 to W/E to use
the Auxiliary Heat in the
Emergency Mode.
