OPERATION
SPAN Setting Mode
Your thermostat is set at the factory to cycle at
0.5˚C (1˚F) above and below the set temperature.
(Span = 2) This setting has been designed to pro-
vide a comfortable room temperature under most
all conditions. However, if you find your system
cycling too fast or too slow, then the Span can be
adjusted to modify the cycle time.
■ Press and hold BOTH for three seconds. The display
will flash, and SPAN will be displayed on the LCD.
■ Press to raise the Span to 3. This setting INCREASES
the cycle time by allowing your system to run
LONGER.
■ Press to lower the Span to 1. This setting
DECREASES the cycle time by causing your
system to run SHORTER.
