Tools Needed

Small Phillips screwdriver

Drill with 3/16- in.(4.8mm) bit

CAUTION

• To avoid electrical shock and to prevent damage to the furnace, air conditioner, and thermostat, disconnect the power supply before installing or servicing the thermostat or any part of the system. This can be done at the circuit breaker.

• Do not reconnect electricity until work is complete.

• Do not short (jumper) across electric terminals at the control on the furnace or air conditioner to test the system. This can damage the thermostat.

• Your thermostat is a precise instrument. Handle it with care.

• All wiring must conform to local codes and ordinances.

• This thermostat is designed for use with 4AA alkaline batteries and/or 24- volt AC C wire (or a 12- 24 AC or DC source) and millivolt gas systems. Each thermostat relay load should be limited to 1.0 amp; higher amperage can cause damage to the thermostat.

Installation Location

To avoid having to move your wiring to a new location, mount the CT102 in place of the old thermostat.

• Install the thermostat on an inside wall of an often-used room, about

5 ft. (1.5m) above the oor.

• Do not install where there are unusual heating conditions, such as: in direct sunlight; near a lamp, radio, television, radiator register,

replace; near hot water pipes in the wall; or near a stove on the

other side of a wall.

• Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room; or in a draft from a stairwell, door, or window.

• Do not locate in a damp area. This can lead to corrosion that will shorten the thermostat’s life.

• Do not locate where air circulation is poor, such as: a corner, an alcove, or behind an open door.

• Do not install the CT102 until all construction and painting is complete.

• This thermostat does not require leveling.

Installation Guide CT102

Getting Started

CAUTION

• Read instructions carefully before removing any wiring from an

existing thermostat.

• Label all wires before disconnecting them form the existing

thermostat.

1. Switch o electricity to the heating and cooling systems. This can

be done at the circuit breaker.

2. Remove the cover from the existing thermostat. Check for locking

screws on the side or front that must be loosened rst.

3. Attach provided labels to each wire for identication. Refer to the

lettered terminal where the wires attach; do not use the color of the wires.

4. Disconnect wires from the existing thermostat, and wind them around a pencil to keep them from falling back inside the wall.

5. Loosen all mounting screws on the old thermostat and remove it from the wall.

Wiring

Prepare Wires

Make sure your wires are labeled. If necessary, nd the “other

end” connection for each wire on your heating or air conditioning equipment and note the label there.

1. Fan out wires so that they are aligned with their terminals.

2. Position wires behind the CT102 and over the terminal area.

3. Do not bunch wires behind the CT102. Feed any slack back into the wall opening.

JUMPER WIRE

If you have both RH and RC connections you must remove the jumper wire between these two terminals.

FROM HVAC SYSTEM

CAUTION

Do not allow wires to touch each other or other parts on the thermostat.

Follow these guidelines for safe and secure wire connections:

• Use at least 2.6 in. of wire for each of your connections to the CT102.

• If you do not have enough wire, splice additional wire to allow enough slack.

• Terminals accept wires from 16-22 awg.

• Remove 1/8 in. insulation from the tip of each wire.

• Take care not to damage the labels for each wire.

Wiring

Connecting Your Wires

Reference the Wire Diagram on page # to identify your wiring diagram and set-up information. If necessary, contact customer support for help.

1. Connect a labeled wire only to a matching lettered terminal.

2. Insert the wire in the terminal well and tighten the screw securely.

The CT102 can be externally powered with a power source rated from 12V to 24V, AC or DC, at 300ma or greater. If used, connect to the C and RH terminals (no polarity).

The 24VAC “C” wire is the other side of the 24VAC heating

transformer and can be found where the other thermostat wires connect at the wall or at the furnace. Do not use the common or ground side of the line voltage.

The CT102 runs on 4 AA alkaline batteries, the C wire (if available), or both batteries and the C-wire. If you do not have a C wire, you can run a new wire from the HVAC or use a standard 12-24V [AC or DC] wall transformer.

The C-wire is optional but preferred for all installations.

Wiring

Mount the CT102 to the Wall

1. Hold the CT102 against the wall, with the wires coming over the

top; above terminal block.

2. Position CT102 for best appearance, cover the hole in the wall.

3. Mark rst and drill a 3/16-in.(4.8mm) hole at each screw location.

4. If you are mounting the CT102 to sheet rock or if you are using the

old mounting holes, use the plastic anchors provided.

5. Attach the CT102 to the wall with the screws provided.

Power Supply

While the CT102 Thermostat can run without batteries on C-wire power, you should install batteries as well to provide power to the unit during outages.

1. Install four (4) AA alkaline batteries following the marked polarity

in the battery compartments. Insert the battery negative end rst

against the spring, then push the positive end in.

2. With all the wires connected and the unit attached to the wall, it

is time to turn the AC power back on. Reconnect the power at the

breaker you used to switch it o. The CT102 will power-up in the

OFF mode.

3. Trip the RESET button to implement the HVAC switch selections.

4. Your CT102 is not yet congured to operate your HVAC system.

You must now congure your thermostat (see page X.)

THERMOSTAT BATTERY CAUTIONS

• Always use new Alkaline batteries.

• Do not use rechargeable batteries of any type. They will no operate the

thermostat properly and may lead to damage.

• Do not mix old and new batteries.

• Do not mix battery types, for example Lithium with Alkaline.

• Do not dispose of batteries in re. Batteries may explode or leak.

• Always replace the batteries as soon as the “Low Batt” warning ashes. The

thermostat is a battery-powered device; you should replace the batteries before they run out, as failure to replace batteries can result in excessive heating or cooling of your house.

• Always replace the batteries once a year, even if the “Low Batt” indicator

does not ash. Replacing the batteries also helps to prevent leakage that

can corrode and damage the thermostat.

• If you are leaving your home for a month or more, you should replace the

batteries as a precaution against battery failure in your absence.

• Failing to replace the batteries when necessary could cause the thermo-

stat to lose power or malfunction. If the thermostat loses power, then the thermostat will not control the temperature, which could result in your HVAC system not functioning as you intended and lead to possible damage from excessive heating or cooling.

• If the thermostat batteries fail with the heat OFF, this can result in NO HEAT

and possible frozen or broken pipes and water damage.

• If the thermostat batteries fail with the cool OFF, this can result in NO COOL

and could cause possible damage or excessive temperatures.
