INSTALLATION
REMOVE OLD THERMOSTAT
1. Shut off electricity at the main fuse box until installation is
complete. Ensure that electrical power is disconnected.
2. Remove the front cover of the old thermostat. With wires
still attached, remove wall plate from the wall. If the old
thermostathasawallmountingplate,removethethermostat
and the wall mounting plate as an assembly.
3. Identify each wire attached to the old thermostat using
the labels enclosed with the new thermostat.

GAS
4. Disconnect the wires from old thermostat one at a time. DO
NOT LET WIRES FALL BACK INTO THE WALL.
5. Install new thermostat using the following procedures.

If you have a single-stage heat pump system, OR your system
uses central electric heat, where the blower is energized by a
separate circuit through the fan relay (meaning that the fan
turns on immediately on call for heat), then the switch on the
back of the thermostat base must be moved to the “ELECTRIC”
position (see fig. 1). If the thermostat is energizing electric heat
sequencers, the switch MUST remain in the “GAS” position.

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
thermostatwillcausedamagetotheunit. Ifnecessary, move
the electric heat switch (see ELECTRIC HEAT SYSTEMS,
above).
Mounting
holes
2. Connect wires beneath terminal screws on base using
appropriate wiring schematic (see figs. 3 through 10).

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. 2, 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.

Primary Control
(located at furnace)
Jumper wire must be
added between R and B
terminals on the primary
control (jumper wire not
provided with thermostat).
BATTERY LOCATION
R

This thermostat requires 3 “AA” alkaline batteries to operate.
Batteries are installed in the thermostat at the factory with a
battery tag to prevent power drainage. You must remove the
battery tag to engage the batteries and provide power to the
thermostat.

To replace batteries, install the batteries along the top of the
base(seefig.2).Thebatteriesmustbeinstalledwiththepositive
