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
