The subbase fan switch controls fan
operation as follows:
ON—Fan operates continuously.
AUTO—Fan operates with cooling equipment as controlled by the thermostat or
with the heating equipment as controlled
by the plenium fan switch. In electric
heat, heat pump, and fan coil systems,
the fan is controlled by the thermostat in
heating and cooling.
Setting Subbase Switches
(If Applicable)
The subbase system switch controls system
operation as follows:
HEAT—Heating system is controlled by the
thermostat. Cooling system is off.
COOL—Cooling system is controlled by the
thermostat. Heating system is off.
OFF—Both the heating and cooling systems
are off. If the fan switch is in the AUTO
position, the fan is also off.
ON—In a cooling only application, only
cooling operates. In a heating only
application, only heating operates.
To switch positions, use thumb or index
finger to slide lever to desired position. Stop
switch lever in detent over the desired function
indicator mark for proper circuit operation.

Inserting Timer Batteries
Power is supplied to the timer by two AAA
alkaline batteries (included.) Install batteries in
thermostat as shown. See Fig. 2. One a year,
or when batteries are dead, replace with two
new AAA alkaline batteries. We recommend
Energizer® batteries. The thermostat itself will
operate without batteries, but will not operate
as a fuel saver.

Setting The Timer
Lift thermostat flip-up cover to find the 24-hour
program dial, slotted in ten-minute increments.
Adjust the timer to the current time by carefully
turning the knob clockwise
. Do not
reverse the knob.
When time is set correctly, the time indicator
arrow (see Fig. 3) will point to the correct time
and corresponding daytime (light) or nighttime
(dark) band of the program dial.

Daylight saving time
When daylight saving time starts, carefully move the knob clockwise

(comfort period); a blue pin is inserted at
10:00 p.m. for low temperature (energy saving
period). Two additional sets of pins are located
in the program pin storage area. You can set
up to six temperature changes with the pins
supplied. We recommend at least five hours for
each energy saving period.
To change the pins or add a new energy
saving period—
• To insert a pin, push it straight into the
selected notch on the program dial until it is
completely seated .
• To remove a pin, press against the program
dial and pull the pin straight out. Do not
attempt to change a pin if it is engaged with
the program index wheel.
• On heating/cooling systems, you must reset
the pins when the seasons change. You will
also probably want to change the lever
positions.
Programming
You can program your thermostat to
automatically lower and raise the temperature
one or more times every 24 hours.
Refer to energy savings chart on the back
cover for typical heating and cooling savings
with your new thermostat.
Before setting your program
Lift thermostat flip-up cover to find the
24-hour program dial. The slots on the program
dial (Fig. 4) are for the program pins that can
be inserted at ten-minute intervals.
Three red and three blue program pins are
included with your thermostat. The red pins
start the high-temperature period; the blue pins
start the low-temperature period. A heating
program is preprogrammed. A red pin is
inserted at 6:00 a.m. for high temperature
12
69-0333—6
24-HOUR PROGRAM DIAL
(GRAY AREA FOR NIGHT SETTINGS)
Setting the heating program:
• Decide when you want the temperature to
reach the comfort level. Find the notch on
the dial that is one-half hour before this time
and insert a red pin. The half-hour head
start gives the furnace time to heat the
house before you wake up or arrive home.
• Decide when you want the energy saving
period to start and insert a blue pin at the
notch that corresponds to this time. After the
blue pin engages, the furnace will be off
until room temperature drops to the energy
saving setpoint.
• You can set both a day and a night program.
See Fig. 5 for programming examples.

• Decide when you want the energy saving

red pin engages, the air conditioner will be
off until room temperature rises to the
energy saving setpoint.

Temporarily changing the program
You may temporarily raise or lower the
temperature if you come home early, stay up
late, plan to be out for the evening, leave on
vacation, etc. You can make a temporary
change one of two ways—moving the program
index wheel or pushing the setting levers
together.
Moving the program index wheel will change
the program just until the next regularly
scheduled change is due:
• Lift the thermostat cover.
• Move the program index wheel counterclockwise
so the time indicator arrow
points to the desired color on the dial.

EXAMPLE: If you are currently at the high
temperature period and want to switch to
the low temperature period, move the wheel
from red to blue. If you are currently at the
low temperature period and want to switch
to the high temperature period, move the
wheel from blue to red. The change will be
in effect until the next regularly scheduled
change.

Pushing the setting levers together will hold
a particular temperature until you change the
levers back. This method is recommended for
a long-term absence:
• Simply push both levers to the temperature
you wish for system control. This temperature will stay in effect until you change the
levers back.

Servicing The Thermostat
System on-length adjustment
NOTE: Not applicable on CT1503 Millivolt Heat
model.
If the thermostat seems to cycle the heating
system too fast or too slow, adjust the heating
system on-length by moving the anticipator
setting lever one indicator mark at a time (Fig. 6);
a higher setting will increase heating system on
length a lower setting will decrease heating
system on-length. Observe the heating system
operation after each adjustment.
The heat anticipator must be correctly set.
An incorrect setting can result in room temperature swings or burn out the anticipator, which
would void the thermostat warranty.

If the readings are different, insert a small
screwdriver in the thermometer slot shown in
Fig. 7, and turn it until both thermometers read
the same.
Replace thermostat cover and put the
system into operation.
Thermometer adjustment
The thermometer was accurately calibrated
at the factory and should only need adjustment
if it was dropped or mishandled.
If the setpoint lever and the thermometer
reading do not agree, follow the procedure
below.
Remove thermostat cover and open the flipup cover.
Set the thermostat cover on a table near the
thermometer of known accuracy.
Allow at least five minutes for the cover
thermometer to sense the area temperature,
then compare the readings. Be careful not to
touch the thermometer or breathe on it.
If the readings are the same, replace the
cover and put the system into operation.
