oPeratIon

The HED series economy duct mount humidity sensors measure the levels of RH and temperature (if equipped) in the air inside a duct. HEDs are warranted to meet accuracy specifications for 1 year. To maintain accurate functionality, keep all pickup vents clear and free of dust, debris, etc.

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 to mount the sensor.

2. Drill a 1” (25 mm) diameter hole in the duct.

3. Insert probe into hole. Mount HED housing to duct using self-tapping screws

(included). Make sure that the gasket on the back of the housing is compressed between the housing and the duct for a secure fit.

4. Remove faceplate. Wire unit.
