PROGRAM DIAL

Programming

You can program your thermostat to automati-

cally lower and raise the temperature one or
more times every 24 hours, depending on the
number of program pins used.

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 10-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
(comfort period); a blue pin is inserted at
10:00 P.M. for low-temperature (energy saving
