STEP 2. REMOVE OLD THERMOSTAT

❑Test 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).

❑Turn off power to the system at the furnace or 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 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.

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

❑Disconnect the wires from the old thermostat. 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 the wires around a pencil as

shown to keep them from falling back into the wall.

Special Installations

Read this section if you are replacing:

• Clock thermostat with separate wires for the clock.

• Thermostat with six or more wires connected to it.

• Thermostat in a heating only system with three wires.

Replacing a Clock Thermostat that has C or C1 Clock Terminals

If you are replacing a Honeywell Chronotherm® Thermostat, you may find one or two

wires going to the C or C1 clock terminals on the Chronotherm wiring wallplate. Do not allow them to touch, or you can

damage the 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.

Replacing a Thermostat that has Six or More Wires

If there are six or more wires (excluding clock wires attached to terminals), you probably have a variation of a

multistage heat pump or other multistage system. This thermostat is not compatible with multistage systems, so return

the product to the place of purchase. For information about which programmable thermostats will work with your

system, call Honeywell Customer Relations Center, at 1-800-468-1502.

Replacing a Thermostat that has Three Wires

If you have three wires for a heating only system and can operate the fan using the fan ON switch this thermostat

works with your system. However, some hot water (zoned) heating systems also have three wires. Your thermostat will

work only if you install an isolating relay on these systems. For details, call your local heating and/or cooling contractor.

STEP 3. MOUNT THERMOSTAT WALLPLATE

❑Separate 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.

❑Position 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.

❑Remove 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.

❑Reposition the wallplate over the holes. Pull the wires through the wiring

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

❑Level the wallplate if desired. Thermostat functions properly when not level.

❑Tighten 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).

❑Match the letter of your old thermostat wire with the corresponding

terminal letter on your new thermostat. Refer to Table 2.

❑Remove the factory-installed jumper connecting terminals R and RC if

wires are connected to both of those terminals.

❑For wiring diagrams, if needed, see pp 22-23.

❑Loosen the terminal screws. Slip each wire beneath its matching

terminal. Wraparound and straight connections are both acceptable,

(see illustration). Tighten the terminals.

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

Table 2. Terminal Designations on Old and New Thermostats

aIf both RH and R terminals are present on existing thermostat, remove jumper and connect Rh to R and R to Rc.

bDo not connect both O and B when wiring to a single stage heat pump. Connect O to O. Tape off B.

cTape off end of the wire with electrical tape and push the taped wire back into the wiring hole in the wall.

STEP 5. INSTALL THE BATTERIES

IMPORTANT

Install three AA alkaline batteries. Batteries must be

installed for programming and operation of the thermostat

and the heating/cooling system.

❑Install the batteries in the wallplate so the positive terminals all

point up (see illustration).

❑If the thermostat is already mounted on the wall, remove the

thermostat by placing your thumb between the thermostat and

wallplate and pulling the thermostat up and away as shown.

When the batteries are running low, a REPL BAT message flashes for one to

two months before the batteries run out completely. Replace the batteries as

soon as possible once the message flashes.

IMPORTANT

Although the thermostat has a low battery indicator, replace the

batteries once per year to prevent leakage and to prevent the ther-

mostat and heating/cooling system from shutting down due to lack

of battery power in the thermostat.

If you insert new batteries within 20 to 30 seconds of removing the old

batteries, the system retains the current time and day. If the display is blank,

the batteries are dead or installed incorrectly. You must reset the time and

day. Refer to Set the Clock for instructions.

As a precaution when leaving home for longer than a month, change batteries before leaving to prevent

the system from shutting down due to lack of power. Always use fresh alkaline batteries. Nonalkaline

batteries do not last as long. They also can leak, causing damage to the thermostat and the wall surface.

STEP 6. SET FAN OPERATION SWITCH

The thermostat fan operation switch, labeled FUEL SWITCH is factory

set in the F position. This is the correct setting for most systems. If your

system is an electric heat system, set the switch to E. The E setting

allows the fan to turn on immediately with the heating and cooling in a

system where the G terminal is connected.
