higher or lower value. The selected number is the number of
degrees, plus or minus, which will be added to the actual
temperature. The number can range between -5 and +5. Factory
default is 0. This adjusted value will be used as actual temperature
for both display and control action. For example, if 2 is selected,
72°F actual will read 74°F. If set point is 72, the room will control
to an actual value of 70 which will be displayed and acted upon as
if it were 72. The effect is that a positive number selection will
make the room temperature lower and vice versa. This thermostat
is factory calibrated within an accurancy of plus or minus 1°F, so
this adjustment will provide the best accuracy when set to 0.
