this digital thermostat. As config-
ured at the factory, this thermostat
will maintain an accurate tempera-
ture. No further adjustment is
necessary, although you can use
these menu items to customize the
performance of the thermostat to
your requirements.

The adjustment range for HEATING
is from 1 to 40 (9 to 40 for heat
pump). The factory preset is 5 (13
for heat pump). The adjustment
range for COOLING is from 9 to
40. The factory preset is 12 (13 for
heat pump). The cooling will not go
below 9 because compressors
require a longer cycle. The adjust-
ment range for AUXILIARY (heat
pump only) is from 1 to 40. The
factory preset is 6.

The chart below shows how this adjustment range affects thermostat
performance.
