Remove Old Thermostat
not compatible with such systems so return
the product to the place of purchase. If you
would like information about which program-
mable thermostats will work with your system,
call Honeywell Customer Assistance 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 will work with your system.
However, some hot water (zoned) heating
systems have three thermostat wires. The
thermostat will not work without installing an
isolating relay on these systems. Call Honey-
well Customer Assistance at 1-800-468-1502
for details.
■■Test to make certain that 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 10°C [50°
F].
■■TURN OFF POWER to system at the
furnace, or at the fuse/circuit breaker panel.
■■Carefully unpack your new thermostat and
mounting plate; save 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.
■■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
masking tape to label it with the old terminal
designation. If there are only two wires, they do
not need to be labeled. Keep the wires from
falling back into the wall by wrapping them
around a pencil, as shown.

One or two extra wires?
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 may damage your transformer. Discon-
nect 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.
Six or more wires?
If there are six or more wires (excluding
clock wires attached to terminals), you
most likely have a variation of a heat pump
or multistage system. The thermostat is

As the batteries are running low, a “bAt Lo”in-
dicator will flash for 1-2 months before 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”indicator,
the indicator will eventually stop flashing. “bAt Lo”
will stay on without flashing to indicate the
thermostat and heating/cooling system have
stopped working when the batteries are almost
completely dead.
After the batteries are completely dead, the
“bAt Lo”indicator will disappear, leaving a
completely blank display.

have to reprogram the thermostat. However, if
the display is blank, the batteries are dead or
incorrectly installed. In this case, you will have to
reprogram. See pages 12-13 to reprogram.
IMPORTANT
Although the thermostat has a low battery
indicator, replace the batteries once a year to
prevent the thermostat and heating/cooling
system from shutting down due to lack of
battery power.
When leaving home for longer than a month,
as a precaution, change batteries before you
leave to prevent system from shutting down due
to lack of battery power.

26°C [78°F], 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
weekdays would not require programs for
“LEAVE”and “RETURN”.
When pressing the keys, use the ball of your
finger or a soft pencil eraser. Use of sharp
fingernails or pencil points may damage the
keypad.
If at any time during programming you make an
error, just press the RUN PROGRAM key, and
continue again at the step where you left off.
sleeping. (Again, lower heat or higher cool.
Although for more comfortable sleeping,
some people choose not to raise the cool
temperature during the night.)
You will set one schedule for weekdays and
another for weekends, since your requirements
will probably be different for each. Also, during
weekends only the “WAKE”and “SLEEP”time
periods are available.
Fill in the times and temperatures you desire for
weekdays and weekends. If you decide not to
program the thermostat, it will automatically
control heating at 20°C [68°F], and cooling at
After the batteries are installed, the thermostat
can be easily programmed in your hand, before
it is installed on the wall.
If you would prefer to program the thermostat
after it is installed on the wall, skip to page 16,
and return later to this programming section.
The following personal programming chart
(pages 10-11) 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”. These periods can be seen
individually on the display as you press the
SET SCHEDULE key.
“WAKE”is the time period you want the
house at a comfortable temperature after you
get up, while you get ready for work or
school. (This will be a higher temperature
during heating season, or a lower tempera-
ture during cooling season.)
“LEAVE”is the time period you can set for an
energy-saving temperature while you are
away at work or school. (This will be a lower
temperature during heating season, or a
higher temperature during cooling season.)
“RETURN”is the time period you want the
house at a comfortable temperature for
activities before bedtime. (Again, higher heat
or lower cool.)
“SLEEP”is the time period you can set for an
energy-saving temperature while you are
