Installation

Verify that you have the right thermostat

Make sure that the CT3200 is the right thermostat for your heating/cooling system. Read the compatibility chart below to determine which system you have. If your system is not compatible with the CT3200, the table recommends an alternate Honeywell model. If you are unsure what type of thermostat is right for your system, visit us on the Web at

www.honeywell.com/yourhome

or call Honeywell Customer Relations at 1-800-468-1502.

Step 1. Prepare for installation

a. Carefully unpack your new thermostat. Save your receipt and make sure you have the following parts:

• Thermostat and mounting plate

• Labels

b. Gather the needed tools and supplies listed below.

Required tools and supplies Optional tools

• Two AA alkaline batteries. Honeywell recommends Energizer® batteries.

• Screwdriver

• Hand or power drill with 3/16-inch or 7/32-inch drill bit

• Pencil

c. Make sure that your heating and cooling systems are working properly. If there is a problem with either system, call a

heating/air conditioning contractor—the problem may persist after you install the new thermostat.

• Screws and anchors

• Installation and Programming Instructions

• Wire cutter/stripper or sharp knife

• Level

• Electrical tape

IMPORTANT:

temperature outdoors is below 50°F (10°C).

d. Inspect the old thermostat wiring.

If the wiring meets any of

the following conditions, see the special wiring

instructions on page 9.

• The old thermostat is a clock thermostat with wires attached to the C or C1 terminals.

• The old thermostat has 6 or more wires, excluding wires attached to C or C1 terminals.

• The old thermostat has 3 wires.

• There are 5 wires

e. Using the enclosed labels, mark the wires with the letter of the

terminal that it is attached to on the

old thermostat

(Fig. 3). Do

not label the wires by color. If the labels do not match the letters on the old thermostat

terminals, see the wiring cross reference table on page 10.

f. Disconnect the wires from the old thermostat and wrap the

wires around a pencil to keep them from

falling back into the

wall.

: Remember, if your old thermostat contains mercury, you

a. Separate the mounting plate from the thermostat using a coin,

as shown in Fig 5.

b. Position the mounting plate on the wall. Be sure the mounting

plate sits flush against the wall and none of the wires are trapped behind it.

c. Level the mounting plate and use a pencil to mark the center of

the mounting plate’s screw holes.

d. Remove the mounting plate and drill holes at the locations you

marked.

• For drywall, drill two 3/16 inch holes.

• For plaster or wood, drill two 7/32 inch holes.

e. If installing in drywall, gently tap the anchors that were provided

into the drilled holes until they are flush with the wall.

f. Reposition the mounting plate over the holes, pull the wires

through the wiring opening, and loosely insert the mounting screws into each of the drilled holes or anchors (Fig. 6).

g. Make sure the mounting plate is level and tighten the mounting

screws.
