Outside Air Temperature Sensor

STE-1451

Installation Guide

Designed specically for outside air temperature
measurement, this device comes in an aluminum LB
enclosure (NEMA 4 and IP66).

For best results, locate the sensor on the north side

of the structure (when located north of the equator)
high under the eaves or another protected area to
prevent incorrect readings from direct sunlight and
damage due to the elements. Also avoid proximity to

other heat sources, power wires, or a large thermal
mass.

1. Run 1/2" conduit through the wall.

2. Aach the conduit to the sensor enclosure’s CW
1/2" NPT ing with a suitable coupler (such as a

Chase closed nipple).

Note: The sensor air holes must face down to

prevent the accumulation of dirt or water.

Connections and Wiring

1. Remove the two cover screws and cover.

NOTE: Removal of only one screw is absolutely

required. The other screw can be loosened,

and the cover can be swung out of the way.

2. Feed wires through the conduit opening.

3. Make connections to the two wire leads with

either bu-splices or solder. (Using wire nuts is

not recommended.) The two-wire sensor is not

polarity sensitive.

4. Plug the conduit with plumber’s puy, painter’s
puy, caulk, or other sealant to prevent air
inltration.

5. Check that the rubber weather gasket is placed

correctly between the enclosure and cover.

6. Reinstall the cover and tighten the screws to

create a weather-resistant seal.
