quIck Install

Observe precautions for handling static sensitive

devices to avoid damage to the circuitry that

is not covered under the factory warranty.

1. Mount the backplate on the wall in an appropriate location. Place so that the

“Install This End Up” statement on the board is in the upper right corner.

2. Wire the unit as shown (see Wiring section).

3. Attach the front plate.

InstallatIon

Observe precautions for handling static sensitive

devices to avoid damage to the circuitry that

is not covered under the factory warranty.

1. Remove the cover by pressing the tab on the bottom of the

sensor while pulling outward on the bottom edge of the

cover.

3.2"

(82 mm)

(34 mm)

4.9"

(123 mm)

2. Position the sensor vertically on the wall, 4 ½ feet (1.5 m) above the oor. Place so

that the “Install This End Up” statement on the board is in the upper right corner.

3. Mount the backplate onto the wall using the screws provided.

oPeratIon

The HEW series economy wall mount humidity sensors measure the levels of RH

and temperature (if equipped) in the air inside a room. HEWs are warranted to meet

accuracy specications for 1 year. To maintain accurate functionality, keep all pickup

vents clear and free of dust, debris, etc.

Six screwholes available; use

a minimum of two for secure

mounting.
