Connecting a DAT sensor
The Discharge Air Temperature sensor is required for automatic changeover and for VAV
terminal units with reheat.

Changeover only
Connect a 10 kΩ, Type 3 thermistor temperature probe to the discharge air temperature
input. The input includes the internal pull-up resistor. An STE-1401 sensor is suitable for this
application. Follow the instructions supplied with the sensor for installation.
l For DAT limiting and reheat, install the sensor in the airflow after the reheat unit. See
the topic, Advanced options on page 35 to enable discharge air temperature control.
l When the DAT sensor is used only to detect primary air temperature, the sensor can be
placed in either location shown in the illustration Discharge air temperature sensor
location.
