Duct Temperature Sensor, Averaging (Flexible)
STE-1415/1416/1417
Mounting
The averaging temperature sensor incorporates sev-
eral discrete sensors encapsulated at equal distances
across the length of the probe. The complete as-
sembly acts as a single sensor to monitor the average
temperature in a duct. Averaging elements are not
recommended for high humidity applications.

The sensors can be installed onto hangers in the
duct using tube clamps or wire ties. They should
be located in a straight section of duct away from
heating, cooling, or humidier elements.
Temperature sensors can be aected by air stratica-
tion in the duct, air leakage through the conduit
or other duct holes, and nearness to exterior walls,
a large thermal mass (e.g., concrete blocks), heat
sources, or wires with power.
Because of air stratication, the coldest air tends to
be toward the boom of the duct. Hence, one of the
sensors should be near the boom of the duct.
The exible cable can be easily shaped to t any duct
size but observe a minimum bend radius of two
inches to prevent damage to wires or sensors.
1. Cut a hole in the duct large enough to feed the
sensor cable through the back of the sensor
enclosure.
2. Fasten the enclosure to the duct by drilling holes
in the duct and threading screws through the
mounting holes in the case.
3. Insert the sensor cable into the duct, stringing the
cable to cover the air path, and secure as needed.
4. For the cable leading to the building automation
system controller, aach conduit to a hole in one
of the sides.

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.
Connections and Wiring
1. Feed wires from the controller through the
conduit opening.
2. Make connections to the two sensor wire leads
with either bu-splices or solder. (Using wire
nuts is not recommended.) The two-wire sensor is
not polarity sensitive.
3. Plug the conduit with plumber’s puy, painter’s
puy, caulk, or other sealant to prevent air
inltration.
