MOUNTING AND WIRING
This thermostat is configured from the factory to operate a heat/
cool, fossil fuel (gas, oil, etc.), forced air system. It is configured
correctly for any system that DOES NOT require the thermostat
to energize the fan on a call for heat. If you system is an electric
heat or heat-pump system that REQUIRES the thermostat to
turn on the fan on a call for heat, locate the ELEC/GAS switch
on the back of the thermostat (see fig. 1) and switch it to the
ELEC position. This will allow the thermostat to energize the fan
immediately on a call for heat. If you are unsure if the heating/
cooling system requires the thermostat to control the fan,
contact a qualified heating and air conditioning service person.
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. The ELEC/GAS switch must be set to match the
type of Auxiliary heat your system uses for proper operation in
the EMERgency mode.
All wiring diagrams are for typical systems only. Refer to
equipment manufacturers’ instructions for specific system wir-
ing information.

Thermostat installation and all components of the

code.
Attach Thermostat Base to Wall
1. Remove the packing material from the thermostat. Gently
pull the cover straight off the base. Forcing or prying on
the thermostat will cause damage to the unit.
2. Connect wires beneath terminal screws on base using
appropriate wiring schematic (see figs. 2 through 3).
3. Place base over hole in wall and mark mounting hole
locations on wall using base as a template.
4. Move base out of the way. Drill mounting holes.
5. Fasten base loosely to wall, as shown in fig. 1, using two
mounting screws. Place a level against bottom of base,
adjust until level, and then tighten screws. (Leveling is for
appearance only and will not affect thermostat operation.)
If you are using existing mounting holes, or if holes drilled
are too large and do not allow you to tighten base snugly,
use plastic screw anchors to secure subbase.
6. Push excess wire into wall and plug hole with a fire-
resistant material (such as fiberglass insulation) to
prevent drafts from affecting thermostat operation.
Battery Location
2 “AA” alkaline batteries are included in the thermostat at the
factory with a battery tag to prevent power drainage. You
must remove the battery tag to engage the batteries.
If “BATT” is displayed, the batteries are low and should be
replaced. For best results, replace all batteries with new
premium brand alkaline batteries such as Duracell® or
Energizer®. To replace batteries, press system button to
OFF, install the batteries along the top of the base (see Fig.
1). The batteries must be installed with the positive (+) end to
the left.
