• Wire cutters/strippers
• Drill with a 3/16 in. (4.8 mm) drill bit
• Level

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 often; position it on an inside wall about 5 ft. (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 drafty 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 it.

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 letters printed near each of the wire terminals.
3. Attach a wiring label (included) to its corresponding wire, so as to identify the wires’ letter; not the wire color
   
   Note
   While labeling the individual wires, DO NOT let the wire fall back inside the wall, as they can be difficult to retrieve.
4. After 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 attach the base to the wall with the two screws provided.

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
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 the 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 Settings.” For electric or oil furnaces, see the additional instructions section under “Fan Jumper.”

Wire/Terminal Identification

• R       Connects to the Heat/Fan Transformer
• RC     Connects to Cool Transformer
• W      Heating Relay—Energized when heating is triggered
• Y       Cooling Relay—Energized when cooling is triggered
• G       Fan Relay—Connects to fan and is energized when either heating or cooling is triggered
• O/B  Heat pump changeover valve in Cool (O) or Heat (B)

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
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 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
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.
