STEP 2. REMOVE OLD THERMOSTAT

❑Test to make certain that your heating and

cooling systems are working properly.If

either 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).

❑Turn off power to system at the furnace, or

at the fuse/circuit breaker panel.

❑Carefully unpack your new thermostat and

wallplate; save package of screws,

instructions and receipt.

❑Remove the cover from the old thermo-

stat. If it does not snap off when pulled

firmly from the bottom, check for a screw

used to lock on the cover.

❑Loosen screws holding thermostat to

subbase, wallplate or wall, and lift away.

❑Disconnect wires from old thermostat or

subbase. As you disconnect each wire,

attach the

enclosed

labels with

the old

terminal

designation.

If there are

only two

wires, they do not need to be labeled.

Wrap wires around pencil to keep them

from falling back into the wall, as shown.

Replacing a clock thermostat that has

C or C1 clock terminals?

If you are replacing a Honeywell

Chronotherm® ClockThermostat, you may

find one or two wires that go to the C or C1

clock terminals on the Chronotherm® wiring

wallplate.Do not allow them to touch, or you

can damage your transformer. Disconnect the

wires and wrap them separately using

electrical tape;do not wrap them together.

Place the wires where they will not interfere

with the operation of the new thermostat.

Record the colors and terminal designation

labels of the remaining wires.

Six or more wires?

If there are six or more wires (excluding clock

wires attached to terminals), you most likely

have a variation of a multistage heat pump or

other multistage system.The thermostat is

not compatible with such systems so return

the product to the place of purchase.If you

would like information about which program-

mable thermostats will work with your

system, call Honeywell Customer Assistance

Center at 1-800-468-1502.

Three thermostat wires?

If you have three wires for a heating only

system and can operate the fan using the fan

ON switch, this thermostat will work with your

system.However, some hot water (zoned)

heating systems have three thermostat wires.

The thermostat will work only if you install an

isolating relay on these systems. For details,

call Honeywell Customer Assistance Center

at 1-800-468-1502.

❑Position wallplate on wall. Level the

wallplate for appearance if desired.Use a

pencil to mark the two mounting holes that

best fit the application.

❑Remove wallplate from wall, and drill

3/16 inch holes in wall (if drywall) as

marked. For firmer material such as

plaster or wood, drill 7/32 inch holes.

Gently tap anchors (provided) into drilled

holes until flush with the wall.

❑Reposition wallplate over holes, pulling

wires through wiring opening.Loosely

insert two mounting screws into holes.

❑Level for appearance only; thermostat

functions properly even when not level.

Tighten mounting screws.

STEP 4. WIRE WALLPLATE TERMINALS

NOTE: All wiring must comply with local

codes and ordinances. If unsure

about household wiring procedures,

call your local heating/air condition-

ing contractor.

Refer to the labels you placed on wires when

you removed your old thermostat.

❑Match the letter of your old thermostat

wire with the terminal of the correspond-

ing letter on your new thermostat.Refer to

illustrations on pages 10, 11, and 12.

Be sure to remove the factory-installed

jumper connecting terminals R and Rc when

wires are connected to both the R and Rc

terminals.

❑Loosen the terminal screws and slip each

wire beneath its matching terminal. Either

straight or wraparound wiring connections

are acceptable (see illustration).Tighten

terminals.

❑Plug the hole in the wall with insulation to

help prevent drafts from adversely

affecting thermostat operation.
