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,
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
.

Connecting power
The controllers require a 24 volt, AC power source. Use the following guidelines when
choosing and wiring transformers to the controller.
l
Use a Class–2 transformer of the appropriate size to supply power to the controller.
l
KMC Controls recommends powering only one controller from each transformer.
l
Do not run 24 volt, AC power from within an enclosure to external controllers.
Connect the 24 volt AC power supply to the power terminal block on the lower right side of
the controller. Connect the ground side of the transformer to the ground terminal
and the
AC phase to the phase
terminal. Power is applied to the controller when the transformer is
connected to power.
