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.

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 specications for 1 year. To maintain accurate functionality, keep all pickup
vents clear and free of dust, debris, etc.

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.
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.
