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
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 has been 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
69-0574—2
up to six temperature changes with the pins
supplied. We recommend at least five hours
for each energy saving period.
