THERMISTOR 1 — TEMPERATURE
This will show the pure thermistor reading with no
offsets taken into account. When placed in ice water
this thermistor should read 32°F in this menu option.

5.
ADJUST THERMISTOR 1 OFFSET
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
CONTACTING TECH LINE.
