INSTALLATION

1. Choose a location on the return air duct.

2. Drill a 7/8” diameter hole in the duct for the sensor probe.

3. Mount the junction box housing to the duct using self-tapping screws (included).

4. Insert the probe through the black swage tting into the duct. Tighten the swage

tting.

5. Wire the probe (see the Wiring section). Leave wires at factory length to allow

for a service loop (to remove the sensor from junction box for service without

disturbing the conduit).

Observe precautions for handling static sensitive

devices to avoid damage to the circuitry that

is not covered under the factory warranty.
