Supply Air Temperature Sensor
The Supply Air Temperature Sensor should be located as close to the rooftop unit
discharge as possible for the best response. Locate the sensor in the center of the widest
part of the duct. Use the supplied template and a 5/16" drill to make a hole for the sensor.
Install the gasket over the probe and mount securely to the duct using the supplied sheet
metal screws. Be sure the gasket is compressed to provide an air-tight seal. For best
accuracy, apply insulation on the outside of the duct, over the sensor. This will help
prevent thermal gradients from affecting the sensor.
