sensor. The selected number is number of degrees, plus or
minus, which will be added to the actual temperature. The
number can range between + 5 and - 5 degrees in 1/2 degree
increments. Factory default is 0. The adjusted value will be
used as the temperature for both display and control
action. For example, if 2 is selected, 72 degrees actual will
read 74 degrees.
Calibrate Outdoor Temperature

sensor. The selected number is number of degrees, plus or
minus, which will be added to actual temperature. The
number can range between + 5 and - 5 degrees in 1/2 degree

temperature sensor. Otherwise this feature operates the
same as for calibration of the indoor (on-board)
temperature sensor.
