Supply Air Temperature Sensor
The OE231 Supply Air Temperature Sensor must be wired as shown
in Figure 9 below for proper operation. The Supply Air Temperature
Sensor is a 10K Type III thermistor sensor. The Supply Air Tempera-
ture Sensor should be mounted in the unit discharge plenum or in the
supply air duct.
NOTE: For Dual Cabinet Units, mount the Supply Air
Temperature Sensor in a Supply Air Ducting area that is common
to both SA Units.
