START UP COMPONENTS
Discharge Air Temperature Sensor
Units are supplied with a Discharge Air Temperature Sensor that is to be field-installed prior to unit
start- up. Installing the Discharge Air Temperature Sensor is required for proper operation.
The sensor is to be installed at least three duct diameters downstream of the heat exchanger.
The sensor must be connected directly to the microprocessor controller. All other sensors and low
voltage devices are to be connected to the low voltage terminal strip in the control center. The
discharge air sensor is shipped loose and can be found in the unit's control center. See the unit-
specific wiring diagram for connection locations.
