RNE Controller

Outdoor Air Temperature Sensor

The OE250 Outdoor Air Temperature Sensor must be wired as shown

in Figure 13 below for proper operation of the RNE Controller. The

Outdoor Air Temperature Sensor is a 10K Type III thermistor sensor.

The sensor should be mounted in the upright position as shown in an

area that is protected from the elements and direct sunlight. Be sure to

make the wiring splices inside of the Outdoor Air Temperature Sensor

weather-tight enclosure.

Figure 13: OE250 – Outdoor Air Temperature Sensor Wiring

CAUTION: Be sure to mount the Outdoor Air Temperature

Sensor in an area that is not exposed to direct sunlight. The shaded

area under the HVAC unit rain hood is normally a good location.

Unused conduit opening(s) must have closure plugs installed and

must be coated with sealing compound to provide a rain-tight seal.

Water can damage the sensor.
