USER MANUAL Low-Voltage Thermostat

Getting started

Check package contents:

• Thermostat

• Coverplate

• Wall anchors & screws (2 each)

• Caution card

• Wire labels

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

Leave wallplate in place.

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.

IGNORE WIRE COLORS: Use only letter designations to identify wire types.

For CT30/CT33: 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 CT31: If your old thermostat has 5 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 - CT31

Drill holes at pencil-marked locations (3/16” holes for drywall, 7/32” holes for plaster). Use hammer to tap anchors into holes until flush with wall. Optional: Pull wires through cover plate (if needed to cover marks left by your old thermostat). 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.

[1] If this wire is present, you may have purchased the wrong thermostat. Call 1-800-468-1502 for help.

Set adjustment lever (CT30/CT31 only)

1. Separate cover from thermostat, and remove the insert.
2. Use a pencil to move the adjustment lever to the proper setting for your system (see table below).

Finish installation

Mount thermostat on base and tighten three mounting screws (CT31 only). Align the 3 tabs on the cover with slots on the thermostat, then push gently until the cover snaps into place. Restore power at the heating/cooling system, or at the fuse/circuit-breaker panel.

Operation

CAUTION: EQUIPMENT DAMAGE HAZARD (CT31).

Do not operate cooling system when outdoor temperature is below 50°F (10°C).
