Tips for Thermostat Location

When replacing an existing thermostat, place your new
Clear Comfort™ thermostat in the same location as the old one, unless
the conditions below suggest otherwise. For a new installation, follow
these guidelines for placement:

• Place the thermostat in a room or hallway that is used oen; position on
an inside wall about 5 . (1.52 m) from the floor.

• Avoid installing the thermostat in unusually heated areas (e.g., near a
television, lamp, radiator, or fireplace), in direct sunlight, or on a wall
that has hot water pipes or that is opposite a stove.

• Avoid installing the thermostat in unusually chilled areas, such as in
a dray area (e.g., stairwell, door, or window), on a wall separating an
unheated room, or where air circulation is poor (e.g., in a corner or
behind a door).

• Avoid installing the thermostat in unusually damp areas as this can lead
to corrosion.

• DO NOT install the thermostat until construction work is complete, dust
free, and painting has been completed.

• If the thermostat housing is cold, wait for it to reach room temperature
before installing.

SYSTEMTYPE

This thermostat is compatible with 1-stage gas furnaces with electric or gas
fan, 1-stage oil systems, 1-stage heat pumps, and 1-stage cooling systems.

Note: This thermostat is not compatible with base board heaters (or other line
voltage heating), multi-stage heating or cooling systems, or 3-wire hydronic systems

Removing the Old Thermostat from the Wall

WARNING: Switch off electricity to both the heating (furnace) and cooling
(air conditioner) equipment before proceeding with the following steps:

1. Remove the front cover from the old thermostat.

2. Before removing wires from the old thermostat terminals, take note

of the leers printed near each of the wire terminals.

3. Aach a wiring label (included) to its corresponding wire,

so as to identify the wires’ leer; not the wire color.

wires, DO NOT let the wire fall
back inside the wall, as they can be
difficult to retrieve.

4. Aer labeling the wires, remove them from the old thermostat

terminals (usually by releasing clamps or undoing terminal screws

5. Remove the old base from the wall (usually by removing screws).

Mounting Your Clear Comfort™ Thermostat to the Wall

1. Remove the thermostat body from the base by gently pulling them apart.

2. Place the base flat against the wall by feeding the wires through
the opening below the wiring terminal.

3. Level the base and mark the holes for the mounting screws with a pencil.

4. Remove the base and drill holes at marked positions;
insert the provided wall anchors.

5. Feed wires back through the opening and aach the base to the wall
with the two screws provided.

1. Strip / 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: 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: 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: If installing your Clear Comfort™ thermostat on a heat pump system,
see the "Installation for Heat Pump Systems" section under "Additional
Thermostat Seings." For electric or oil furnaces, see the additional
instructions section under "Fan Jumper."

Completing the Installation

1. Insert two Energizer® or Duracell® alkaline AAA baeries (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
Seings.")

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: 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.

Replacing the Baeries
It is recommended that the baeries in the thermostat be replaced once a

year or before leaving the home for a prolonged period of time.
WARNING: Failure to change baeries 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 baeries.

3. Replace them with fresh Energizer® or Duracell® alkaline AAA baeries,
carefully observing the required polarities.

4. Reinstall the thermostat body onto its base by gently pushing it until it
“clicks” into place.

Reset Buon: Use to reset all
system display seings and
temperature gauges back to
factory defaults. (To gain access

Note: Be careful not to touch the
green surface on which the Reset
Buon is mounted, and do not
clean it if dusty.

to the Reset Buon, remove the
thermostat body from its base by
gently pulling them apart.)

• Reset Buon—Press and hold
for five seconds to reset your
thermostat

Fahrenheit or Celsius Adjustment:

Set the temperature to read in either °F or °C.

• Slide the Mode Switch to the Off position (Step 1). While holding the
Reset Buon (on the back of the thermostat body), press the Up Arrow
Buon to toggle between °F or °C (Step 2).

Temperature Offset:

Offset the temperature display to read +/- 9° F or +/- 4.5° C.

• Slide the Mode Switch to the Off position
(Step 1). While holding the Reset Buon (on the back of the thermostat
body), press the Down Arrow Buon until the Offset Indicator appears
(Step 2). Release the Reset Buon. (Do not hold the Reset Buon
for more than five seconds.) Use the Arrow Buons to pick the offset
temperature amount. The thermostat will accept the chosen offset aer
10 seconds of no activity, or by sliding the Mode Switch to Heat or Cool.

Installation for Heat Pump Systems:

If installing your Clear Comfort™ thermostat on a heat pump system,
the following instructions are necessary.

• Insert the additional jumper (included) into the Y and W terminals.

• If a B wire is part of your installation, connect it to the O/B terminal.

Move the jumper located near the right edge on the back of the
thermostat body from the Cool (O) position on the pins to the Heat (B)
position on the pins. If an O wire is part of your installation, connect it to
the O/B terminal. Leave the jumper on the Cool (O) position.

ADDITIONALTHERMOSTATSETTINGS

Seings in this section are not necessary for all systems. These seings,
however, may optimize energy use and comfort levels, especially if a heat
pump system is being used.

System Type Adjustment: Your Clear Comfort™ thermostat is set at

the factory to operate a standard fossil fuel furnace heating system. This
seing can be changed to beer accommodate other heat sources, fan
types or a heat pump system.

• Slide the Mode Switch to the OFF position (Step 1). While holding the
Reset Buon (on the back of the thermostat body), press the Down Arrow
Buon until the Offset Indicator appears (Step 2). Release the Reset
Buon. (Do not hold the Reset Buon for more than five seconds.) Press
the Reset Buon again (Step 3). (The Offset seing will not be lost.) If
using a heat pump, toggle to “HP” using the Up or Down Arrow Buons.
To return to the furnace seing (“F”), press the Up or Down Arrow Buon
(Step 4). The thermostat will accept the seing aer 10 seconds of no
activity, or by sliding the Mode Switch to Heat or Cool.

Fan Jumper: Correct placement of this jumper optimizes energy use and

comfort levels for the connected system type.

• For electric and heat pump systems, move the jumper located in the top­right corner on the back of the thermostat body from the Gas/Oil Heat
position on the pins to the Electric Heat position.

• For gas or oil systems, verify that the jumper is in the Gas/Oil
Heat position.

Minimum Cycle Period Adjustment:

The cycle period is the minimum time in minutes between each heating or
cooling cycle. As a default, your thermostat’s minimum cycle period is set
to optimize energy use and comfort levels. The default can be changed
