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 boom, remove it.
Connections and Wiring
1. Remove the two cover screws and cover.
NOTE: Removal of only one screw is required. The
other screw can be loosened, and the cover
can be swung out of the way.
2. Feed wires through the conduit opening.
NOTE: Use 18 to 24 AWG shielded wiring for all
connections. Do not locate the device wires
in the same conduit with wiring used to
supply inductive loads such as motors.
Make all connections in accordance with
national and local codes.
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 sealant to prevent air
inltration.
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 specically for outside air temperature
measurement, this device comes in an aluminum LB-
style enclosure.
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, vents, power wires, or a large
thermal mass.
1. Run 1/2" conduit through the wall.
2. Aach 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.
