Programming
You can program your thermostat to
automatically lower and raise the temperature
one or more times every 24 hours.
Before Setting Your Program
Lift thermostat flip-up cover and you’ll find
the 24-hour program dial. The slots on the
program dial (Fig. 4) are for the program pins
which 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 was preprogrammed. A red pin is
inserted at 6:00 AM for high temperature
(comfort period); a blue pin is inserted at
10:00 PM 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 savings period.
To change the pins or add a new energy
savings 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 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
remove the program pins from the heating
program to set new times for your cooling
program. Write down your colors and time
for reprogramming at the next heating
season. Also, you may want to change the
temperature setting lever positions.
Setting the Heating Program
Decide when you want the temperature to
reach the comfort level. Find the notch on the
program 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.
