2 REMOVE OLD THERMOSTAT

❑ Test to be sure your heating and air conditioning

systems (where applicable) are working correctly. If

not, 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).

Not compatible with any 120/240 volt circuit.

aCompatible with 2-wire Honeywell zone valves. Isolating relay required for zone valves that have a 3-wire thermostat

connection.

CAUTION

Equipment Damage Hazard.

Handling wires during installation can

damage equipment.

Disconnect power at furnace or main breaker/

fuse box before beginning installation.

❑ Carefully unpack your new thermostat and wallplate

and save package of screws, instructions and receipt.

❑ Remove the cover from the old thermostat. If it does

not snap off when pulled firmly from the bottom, check

for screw that locks 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, use the wiring labels

(enclosed) to label each wire with the old terminal

designation. If there are only two wires, they do not

require labeling. Wrap wires around a pencil to keep

them from falling back into the wall as shown in Fig. 2.

Replacing Clock WIth C or C1 Clock

Terminals

If you are replacing a Honeywell Chronotherm®

Thermostat, you may find one or two wires that go to the

C or C1 clock terminals on the Chronotherm®

Thermostat 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. Do not place the wires where

they can interfere with the new thermostat operation.

Record the colors and terminal designation labels of the

remaining wires.

Six or More Thermostat Wires

If there are six or more wires connected to the thermostat

(excluding clock wires attached to terminals), you

probably have a variation of a multistage heat pump or

other multistage system. The thermostat is not

compatible with these systems, so return the product to

your retailer. If you want information about which

programmable thermostats work with your system, visit

our Web site at www.honeywell.com/yourhome or call the

customer information line at 1-800-468-1502.

Three Thermostat Wires

If you have three wires for heating only and can operate

the fan using the Fan On switch, this thermostat works

with your system. However, some hot water (zoned)

heating systems have three thermostat wires. The

thermostat works only if a contractor installs an isolating

relay on these systems. For details, contact a local

heating/cooling contractor.
