Balancing Indoor/Outdoor Temperature Readings
The control console includes a balancing potentiometer to make
the OUT TEMPERATURE agree with the IN TEMPERATURE. The value
is mostly cosmetic since a 10°F error only yields a 1% error.
Because overall equipment accuracy is 5%, chasing this 1% is not too
significant. Ensure IN and OUT probes are at the same temperature
for 10 minutes. OUT is on the UMBILICAL cord; IN is at the control
console. Turn the adjuster located to right of the thermometer
CLOCKWISE to DECREASE OUT reading; COUNTER-CLOCKWISE to INCREASE OUT.

get at the backside of the Thermometers. Figure 2
You will need to lay the Thermometers on their face to get
