Mounting

Maintenance

No routine maintenance is required. Each compo-

nent is designed for dependable, long-term reliability

and performance. Careful installation will also

ensure long term reliability and performance. If dirt

clogs the air holes at the boom, remove it.

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.

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.
