ADJUST THERMISTOR 1 OFFSET
5.
This calibration is only to be used if actual temperature
at thermistor #1 is off from set point.
By adjusting the offset higher we can force the unit to
drive the temperature down below the set point.
(example: adjusting from 0 to +2 will drop the unit
temperature 2 degrees)
DO NOT MAKE AN ADJUSTMENT TO THIS WITHOUT
