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

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.

The SS/HP switch is factory set to the SS position. In this
position, 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).

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
circulator 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
thermostat will always power the circulator fan on a call for
heat in the HEAT mode.

2 "AA" alkaline batteries are included in the thermostat. To
install 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.

. We recommend replacing batteries every 2
years. If the home is going to be unoccupied for an extended
period (over 3 months) and
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
offset will occur within two days if batteries are not replaced.
