The Thermistor Type III sensor readings can be calibrated. Enter a
Positive value to increase a reading and a Negative value to decrease
a reading.
Note:
The Supply Air Temperature calibration offset only
operates on the reading when the VAV/Zone Controller
has its own Supply Air Temperature sensor installed on
the AUX2 input. If the supply temperature is received
from a global broadcast, you will need to go to the air
handler to calibrate the temperature reading.
