Loosen screws holding thermostat to  
subbase, wallplate or wall, and lift away.  
Disconnect wires from old thermostat or  
subbase. As you disconnect each wire,  
attach one of the enclosed labels to each old  
terminal designation. If there are only two  
wires, they do not need labeling. If there is  
an extra wire that is not connected to your  
old thermostat, you also do not connect it to  
your new thermostat. Keep the wires from  
falling back into the wall by wrapping them  
around a pencil as shown.  
Step 2. Remove Old Thermostat  
Test to be sure your heating and cooling  
systems are working properly. If either 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 at the fuse/circuit breaker panel.  
Carefully unpack your new thermostat and  
mounting plate, saving package of screws,  
instructions and receipt.  
Remove cover from old thermostat. If it does  
not snap off when pulled firmly from the  
bottom, check for a screw used to lock on  
the cover.

those systems so return the product to the  
retailer. If you want information about the  
programmable thermostats that work with your  
system, call Honeywell Consumer Services at  
1-800-468-1502.  
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 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. Place the wires where  
they do not interfere with the operation of the  
new thermostat. Record the colors and terminal  
designation labels of the remaining wires.  
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 does  
not work without installing an isolating relay on  
these systems. For details, call Honeywell  
Consumer Services at 1-800-468-1502.  
Six or more wires?  
If there are six or more wires (excluding clock  
wires attached to terminals), you probably have  
a variation of a heat pump or multistage  
system. This thermostat is not compatible with

Step 3. Install Batteries  
IMPORTANT  
Batteries must be installed for the pro-  
gramming and operation of the ther-  
mostat and heating/cooling system.  
Purchase two AA alkaline batteries; non-  
alkaline batteries do not last as long, and  
can leak, causing damage to the thermostat  
or the wall surface. We recommend  
Energizer® batteries.  
Open the top cover of thermostat to access  
control panel and battery compartment.  
Make sure the thermostat is set to the Off  
position.

Install the fresh batteries as shown, making  
sure positive and negative terminals are  
oriented correctly.  
After the batteries are completely dead, the  
bAtLo indication disappears, leaving a  
completely blank display.  
Replace the battery cover.  
INSTALL TWO AA ALKALINE  
BATTERIES AS SHOWN  
As the batteries run low, a bAt Lo indicator  
flashes for one to two months before the  
batteries run out completely. Replace the  
batteries as soon as possible after the indicator  
starts flashing. If you do not replace the  
batteries sometime during the flashing bAt Lo,  
the indicator eventually stops flashing. bAt Lo  
then stays on without flashing, indicating the  
thermostat and heating/cooling system have  
stopped working and the batteries are almost  
completely dead.

Press down on the left ends of batteries to  
remove them. If you insert the new batteries  
within 20 to 30 seconds of removing the old  
ones, you do not need to reprogram the  
thermostat. However, if the display is blank, the  
batteries are dead or incorrectly installed and  
you must reprogram. See Step 4.  
IMPORTANT  
Although the thermostat has a low bat-  
tery indicator, replace the batteries  
once a year to prevent the thermostat  
and heating/cooling system from shut-  
ting down due to lack of battery power.  
As a precaution, when leaving home  
for longer than a month, change bat-  
teries before you leave to prevent the  
system from shutting down due to lack  
of battery power.

WAKE is the time period you want the house  
at a comfortable temperature when you get  
up and while you get ready for work or  
school. (This is a higher temperature during  
heating season and a lower temperature dur-  
ing cooling season.)  
LEAVE is the time period you can set for an  
energy-saving temperature while you are  
away at work or school. (This is a lower tem-  
perature during heating season and a higher  
temperature during cooling season.)  
RETURN is the time period you want the  
house at a comfortable temperature for activ-  
ities before bedtime. (This is a higher tem-  
perature during heating season and a lower  
temperature during cooling season.)  
SLEEP is the time period you can set for an  
energy-saving temperature while you are  
sleeping. (This is a lower temperature during  
the heating season and a higher tem-  
perature during the cooling season.)  
Step 4. Program Thermostat  
After the batteries are installed, the thermostat  
can be easily programmed in your hand before  
it is installed on the wall.  
If you prefer to program the thermostat after it is  
installed on the wall, go to Step 7 and return  
later to this programming section.  
The Personal Programming Chart, Tables 2 and  
3, may be helpful for planning your program  
schedule of time and temperature settings for  
various times of the day.  
Four time periods are available during  
weekdays WAKE, LEAVE, RETURN, and  
SLEEP; view these periods individually on the  
display as you press the Weekday key.

Set one schedule for weekdays and another for  
weekends because your requirements are  
usually different for each. Also, during week-  
ends, only the WAKE and SLEEP time periods  
are available.  
If no program is entered for the weekends, the  
thermostat operates on the weekday SLEEP  
program all weekend.  
Before programming, remove the clear plastic  
overlay covering the display.  
Fill in the times and temperatures you desire for  
weekdays and weekends. If you decide not to  
program the thermostat, it automatically con-  
trols heating at 68°F (20°C), and cooling at 78°F  
(26°C), 24 hours a day. Also, you do not need to  
enter a time and temperature program for all  
periods if your schedule does not require it. For  
example, a house that is occupied during week-  
days would require programs only for WAKE  
and SLEEP.  
When pressing the keys, use the ball of your  
finger or a soft pencil eraser. Using sharp finger-  
nails or pencil points can damage the keypad.  
If you make an error at any time during program-  
ming, just press the Run Program key, and  
continue again at the previous step in your  
sequence.

optimized according to the type of system to  
maximize comfort. Setting the screw out one  
turnmeans turning the screw approximately  
360° counterclockwise, or about one com-  
plete turn.  
Step 5. Adjust Fan Operation  
Switch, As Required  
The thermostat fan operation switch, labeled  
FUELSWITCH (see illustration) isfactory-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 to allow the  
fan to turn on immediately with the heating in  
a system when the G terminal is connected.

In the unlikely event that you want a longer  
furnace on-time, readjust screws A and/or B as  
follows:  
IMPORTANT  
When using a high efficiency furnace  
such as a 90 percent or greater Aver-  
age Fuel Utilization Efficiency (AFUE)  
unit, adjust screw A out one turn and  
leave screw B in.  
First, turn both screws in completely, then  
adjust for system type:  
Warm Air FurnaceSet at the Hot Water  
setting (Aout one turn, Bleave in).  
Electric FurnaceLeave at the Warm Air  
Furnace setting (Aleave in, Bleave in).  
The thermostat is set to read the temperature  
in degrees Fahrenheit. If readings are  
desired in degrees Celsius, adjust screw C  
out one turn.  
NOTE: This thermostat does not have a set-  
ting for steam/gravity air; cycles would  
not be long enough for accurate tem-  
perature control.
