STEP 1. PREPARE FOR INSTALLATION

qThis thermostat is designed to work with multistage heat pumps (heat pumps with Auxiliary and/or Emergency

Heat). Check Table 1 in Step 4 to make sure the CT3611 is compatible with your system. If you have

compatibility questions, contact Honeywell at www.honeywell.com/yourhome or call the Customer Relations

Center at 1-800-468-1502.

Package Contents

• Thermostat • Wiring labels

• Screws and anchors • Owners manual

• Wallplate

Tools Required

• Screwdriver

• Drill

STEP 2. REMOVE OLD THERMOSTAT

qTest your heating and cooling systems to make sure they work properly. If either system does not work, contact

your local heating/air-conditioning dealer. To avoid compressor damage, do not operate the cooling system when

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

qTurn off power to the system at the furnace or the fuse/circuit breaker panel.

qCarefully unpack your new thermostat and wallplate. Save package of screws, instructions, and receipt.

qRemove the cover from the old thermostat. If the cover does not snap off when pulled firmly from the bottom, check

for a screw or screws used to lock on the cover.

qLoosen the screw or screws holding the thermostat to the wallplate and lift the thermostat away.

qDisconnect the wires from the old thermostat. As you disconnect each wire, attach

the enclosed labels with the old terminal designation. Wrap the wires around a

pencil as shown to keep them from falling back into the wall.

STEP 3. MOUNT THERMOSTAT WALLPLATE

qSeparate the wallplate from the thermostat by placing your thumb or fingers

between the bottom of the wallplate and the thermostat, and pulling the

wallplate up and away from the thermostat. See illustration at right.

qPosition the wallplate on the wall. Level the wallplate for appearance if desired.

Use a pencil to mark the two mounting holes that best fit the application.

qRemove the wallplate from the wall. Drill two 3/16 in. holes in wall (if drywall) as

shown. For materials such as plaster or wood, drill 7/32 in. holes where marked.

Gently, tap the (provided) anchors into the drilled holes until they are flush with

the wall.

qReposition the wallplate over the holes. Pull the wires through the wiring

opening. Loosely insert mounting screws into each of the holes.

qLevel the wallplate if desired. Thermostat functions properly when not level.

qTighten mounting screws.

STEP 4. WIRE WALLPLATE TERMINALS

IMPORTANT

All wiring must comply with local codes and ordinances. If

unsure about household wiring procedures, call your local heat-

ing/air-conditioning contractor.

Refer to the labels you placed on the wires when you removed the old

thermostat (see illustration).

qMatch the letter of your old thermostat wire with the corresponding

terminal letter on your new thermostat. Refer to Table 1.

qFor wiring diagrams, if needed, see page 21.

qLoosen the terminal screws. Slip each wire beneath its matching

terminal. Wraparound and straight connections are both acceptable,

(see illustration). Tighten the terminals.

qPlug the hole in the wall with insulation to help prevent drafts from adversely affecting thermostat operation.

qMatch the terminals from your old thermostat to the terminals on the CT3611. Find the column from Table 1 that

matches your existing thermostat wire terminals to help you match the terminals correctly.

IMPORTANT

If you have any wiring questions, contact Honeywell at www.honeywell.com/yourhome or call Honeywell

Customer Relations Center, toll-free, 1-800-468-1502.

aNever attach wires to both the O and B terminals on the CT3611. If the old thermostat had wires on both the O and B

terminals, be sure to attach the B wire to the CT3611 C terminal. If another wire is already matched to the C terminal,

contact Honeywell.

bIf the old thermostat had separate wires on both the V and VR terminals, some system modification is required. Call

your local heating and cooling contractor for assistance.

cIf the old thermostat had wires on W1, Y1 and W2 terminals, then remove the CT3611 factory-installed jumper

between Y and W1 terminals and match the old W1 to W1, Y1 to Y and W2 to W2.

dUse electrical tape to tape off the end of the wire and push the taped end back into the wall wiring hole.
