STEP 1. PREPARE FOR INSTALLATION
❑ Check Table 1, the compatibility chart, to make sure the thermostat is compatible with your system. If your system
is not compatible, call Honeywell Customer Relations Center, toll-free, 1-800-468-1502.

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:

WALL OPENING
•
•
•
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.
M5136
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.
FOR WRAPAROUND
INSERTION STRIP
7/16 IN. (11 MM).
FOR STRAIGHT INSERTION
STRIP 5/16 IN. (8 MM).

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.
INSTALL 3 AA ALKALINE BATTERIES
AS SHOWN, POSITIVE (+) TERMINALS
TOWARD TOP.
M10622
9
69-1642
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.
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. 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.

SMART RESPONSE™ TECHNOLOGY
Your CT3600/CT3697 is actually a small computer. The Smart Response technology calculates the correct time of day
to turn on your heating or cooling system. Smart Response technology considers the following information.
•
