quIck Install
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
1. Choose a location on the air duct.
2. Drill a 1” (25 mm) diameter hole for the sensor probe.
3. Mount HED housing to duct using self-tapping screws (included).
4. Wire unit (see Wiring section).
