Before you begin, make sure you have:

• No. 2 Phillips & small pocket screwdrivers
• Hammer
• Level (optional)
• Pencil
• Drill and bit (3/16” for drywall, 7/32” for plaster)

Remove your old thermostat

TURN OFF the POWER at the heating/cooling system (or fuse/circuit-breaker panel). Remove the cover and thermostat, but leave the wallplate with wires attached.

MERCURY NOTICE
If your old thermostat contains mercury, contact your local waste management authority for proper disposal instructions.

Label wires and remove old wallplate

Use a screwdriver to disconnect wires one by one. As you disconnect each wire, wrap it with the label matching the letter on your old thermostat. (Adhesive labels are supplied in your
thermostat package.) Remove the old wallplate only after all wires are labeled. Be careful not to let loose wires fall into the wall opening. Wrap supplied labels securely around each wire. Do not let wires fall into a wall opening

For CT50/CT53/CT54
If your old thermostat has 3 or more wires (not counting terminals C or C1), you may have purchased the wrong replacement thermostat. Stop now and call 1-800-468- 1502 for advice.

For CT51/CT55
If your old thermostat has 7 or more wires (not counting terminals C or C1), you may have purchased the wrong replacement thermostat. Stop now and call 1-800-468- 1502 for advice.

Mark mounting position

Mount thermostat base

1. Drill holes at pencil-marked locations (3/16” holes for drywall, 7/32” holes for plaster).
2. Use hammer to tap anchors into holes until flush with wall.
3. Pull wires through thermostat base and insert screws. Check level if desired, then tighten screws.

Connect wires

1. Match each labeled wire with same letter on terminal.
2. Use a screwdriver to loosen screw terminals, insert bare wires beneath screws, then tighten screws.
3. Push any excess wire back into the wall opening.

Labels don’t match?
If labels do not match letters on thermostat, see table below.

Wiring CT51/CT55

1. If wires will be connected to both R and Rc terminals, remove the metal jumper.
2. Do not connect both O and B if you have a heat pump. Connect only the O wire. Wrap B wire with electrical tape and do not use.
3. Do not use C, X or B. Wrap bare end of wire with electrical tape.

Set fan operation switch (CT51/CT55)

Move the switch to the proper setting for your system:
F: For gas or oil heating systems, leave the fan operation switch in this factory-set position (for systems that control the fan in a call for heat).

E: Change the switch to this setting for heat pump or electric heat systems. (This setting is for systems that allow the thermostat to control the fan in a call for heat, if a fan wire is connected to the G terminal.)

Set heat anticipator (select models)

Move the adjustment arrow to the proper setting for your system (see table below).

Finish installation

1. Align the slots on the cover with tabs on the sides of the base, then push gently until the cover snaps into place.
2. Restore power at the heating/cooling system, or at the fuse/circuit-breaker panel.

Adjust to set desired indoor temperature.
