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.
For DAT limiting and reheat, install the sensor in the airflow after the
reheat unit. See the topic,
Advanced options on page 37 to enable
discharge air temperature control.
When the DAT sensor is used only to detect primary air temperature,
the sensor can be placed in either location shown in the illustration
