STEP 1. PREPARE FOR INSTALLATION
❑ Check the contents of your thermostat package to be sure all items are included.
Package Contents
•
•
Thermostat
•
•
Wallplate
•
Owner’s Guide
Wiring labels
Screws and anchors
❑ Locate the required tools to install your thermostat.
Tools Required
•
•
•
Screwdriver
Hammer
Level
•
•
Drill
•
Drill bits: 3/16 in. for drywall;
7/32 in. for plaster
Needle-nose pliers
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.

Replacing a Clock Thermostat that has C or C1 Clock Terminals
When 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 Care 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 wallplate from thermostat by placing your thumbs between bottom of wallplate
and thermostat and pulling wallplate up and away from thermostat. See illustration.
❑ Position wallplate on wall. Level wallplate
for appearance, if desired. Use a pencil to mark

STEP 4. WIRE WALLPLATE TERMINALS
IMPORTANT
All wiring must comply with local codes and ordinances.
If unsure about household wiring procedures, call your
local heating/air-conditioning contractor.
Refer to the labels you placed on the wires when you removed
the old thermostat (see illustration).
❑ Match the letter of old thermostat wire with the corresponding
terminal letter on new thermostat. Refer to Table 1.
❑ Remove factory-installed jumper connecting terminals R and
RC if wires are connected to both of those terminals.
❑ For wiring diagrams, if needed, see Wiring Diagrams section.
❑ Loosen terminal screws. Slip each wire beneath matching
terminal. Wraparound and straight connections are both
acceptable, (see illustration). Tighten terminals.
❑ Plug the hole in the wall with insulation to help prevent
drafts from adversely affecting thermostat operation.

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

❑ 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
on the next page.

❑ 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 Step 9. Set the Clock for instructions.
M16424
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 and 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.
