STEP 2. REMOVE OLD THERMOSTAT  
q
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).  
q
q
q
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.  
q
q
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  
WIRES THROUGH  
WALL OPENING  
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.  
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 Care at 1-800-468-1502.  
69-1199—4

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  
q
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.  
q
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.  
M16427  
q
q
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

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).  
q
Match the letter of your old thermostat wire with the  
corresponding terminal letter on your new thermostat. Refer to  
Table 2.  
q
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 pages 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.

69-1199—4  
 
q
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 thermostat and heating/cooling sys-  
tem from shutting down due to lack of battery power in  
the thermostat.  
M16424  
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 or cooling in a system  
where the G terminal is connected.

SMART RESPONSE™ TECHNOLOGY  
Your thermostat 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.  
Air temperature.  
Wall temperature.  
The time of day when you want the comfort temperature established.  
When the thermostat activates Smart  
Response technology, the thermostat  
displays In Recovery, changes the  
setpoint, and turns on the system.
