Both the Heating Stages and the DX Cooling Stages utilize Staging
Up and Down Delay Periods between stages and Minimum Run Times
and Off Times.
Both modes have their own set of Staging and Run Delay times. The
Heating timer screens look exactly the same as the Cooling except they
reference the Heating instead of Cooling.
See the VAV/CAV Controller Technical Guide for information on how
these Delays and Run Times are used.

Setpoint Screen #32 - Sensor Calibration for
SPC, SAT & RAT
Sensor Calibration
SPC: XX.Xº 0.00º
SAT: XX.Xº 0.00º
RAT: XX.Xº 0.00º
If the Space, Supply, or Return Air Temperature Sensors are reading
incorrectly, you can use this option to enter an offset temperature to
adjust the Sensor’s Temperature. Enter a positive Sensor Calibration
value to raise the Space Temperature Sensor, Supply Air Temperature
Sensor, or Return Air Temperature Sensor reading and a negative value
to lower the Sensor reading.
Description Minimum Default Maximum
Sensor Calibration SPC -100.0ºF 0.0ºF +100.0ºF
Sensor Calibration SAT -100.0ºF 0.0ºF +100.0ºF
Sensor Calibration RAT -100.0ºF 0.0ºF +100.0ºF
Setpoint Screen #33 - Sensor Calibration for
OAT
Sensor Calibration
OAT: XX.Xº 0.00º
If the Outdoor Air Temperature Sensor is reading incorrectly, you can
use this option to enter an offset temperature to adjust the Sensor’s
Temperature. Enter a positive Sensor Calibration value to raise the
Outdoor Air Temperature Sensor reading and a negative value to lower
the Sensor reading.
