Return T Sensor PTC or NTC—This parameter selects the type of sensor being used for the return
air sensor.
Return T Sensor—This parameter can provide an offset to the actual sensor reading to calibrate the
units sensor to other sensors.
Calibrated Return T Sensor—This parameter is the reading after the offset has been added to or
subtracted from the actual sensor reading.
Supply T Sensor PTC or NTC—This parameter sets the type of sensor that is connected to the
unit. It is set at the factory as NTC and should be changed only by a certified Emerson technician.
Supply T Sensor—This parameter can provide an offset to the actual sensor reading to calibrate the
unit's sensor to other sensors.
Calibrated Supply T Sensor—This parameter is the reading after the offset has been added to or
subtracted from the actual sensor reading.
CW T Sensor—This parameter can provide an offset to the actual sensor reading to calibrate the
unit's sensor to other sensors.
Calibrated CW T Sensor—This parameter is the reading after the offset has been added to or
subtracted from the actual sensor reading.

This unit can be equipped with a total of 20 rack sensor readings or 10 2T temperature sensor
modules. This menu provides the ability to calibrated by entering a negative or positive offset. The
calibrated reading is displayed in the far right column. If a value is not shown in the far right column,
then the sensor is either not setup correctly or is not connected.
