Connecting the Wires to the Terminal
1. Strip 3/8 in. (9.5 mm) insulation from the end of each wire.
2. Loosen the screws on each terminal. Connect each wire to its
appropriate terminal (matching the label on the wire to the label on
the terminal) and tighten the terminal screw to secure the wire.
3. Completely wrap exposed areas of any unused wire with electrical
tape and push them back into the wall hole.

Note: Do not let the wires touch each
other or other parts of the thermostat.
Be sure that all wires are routed
through the opening on the thermostat
base, then into the proper terminals.
CAUTION: Stripping too much
insulation from the end of a wire
creates the potential for shorting
between wires and could prevent
proper function of the thermostat.
Note: Verify that both systems are working properly
by feeling for warm air when the thermostat is in Heat
Mode and cool air when it is in Cool Mode.

Completing the Installation
1. Insert two Energizer® or Duracell® alkaline AAA batteries (not
included) into the appropriate spaces on the back of the thermostat
body.
2. Verify that the Fan Jumper is in the correct position for your system
type. (See the "Fan Jumper" section under "Additional Thermostat
Settings.")
3. Install the thermostat body by gently pushing it onto the base until it
"clicks" into place. Verify that there are no gaps in the side housing.
4. Switch on the electricity to both the heating (furnace) and cooling (air
conditioner) sources.

Note: If the batteries are not changed
within 7 days after the Low Battery
Indicator appears on the display, the
set temperature will increase by 10°F
in Cooling Mode, or decrease by 10°F
in Heating Mode as a further reminder.
After 90 days or less, depending on
the condition of the batteries, the
system will turn off and the Low Battery
Indicator will flash on the display.

Replacing the Batteries
It is recommended that the batteries in the thermostat be replaced once a
year or before leaving the home for a prolonged period of time.
WARNING: Failure to change batteries in a timely fashion can lead to
uncontrolled heating and cooling.
1. Remove the thermostat body from its base by gently pulling them apart.
2. Turn the thermostat over and remove old batteries.
3. Replace them with fresh Energizer® or Duracell® alkaline AAA batteries,
carefully observing the required polarities.
4. Reinstall the thermostat body onto its base by gently pushing it until it
“clicks” into place.

Note: Not having an available wire for
every terminal is normal for some systems.
Note: If you do not have both an R and
RC wire, insert the wire you do have, R
or RC, with the pre-installed jumper wire
(included) that connects the R and RC
terminals. If you have both and R and
RC wire, remove the jumper wire before
connecting the R and RC wires.
Note: If installing your Clear Comfort™ thermostat on a heat pump system,
see the "Installation for Heat Pump Systems" section under "Additional
Thermostat Settings." For electric or oil furnaces, see the additional
instructions section under "Fan Jumper."
