Wall-Mounted Humidity Sensor (P/N 203-5751)
CPC specs a wall-mounted relative humidity (RH) sensor with a 0-5VDC output for use in build-
ing control and anti-sweat control applications using CPC input boards.

Coefficient
Choosing a Mounting Location
Mount the sensor indoors in a central location within the zone to be measured, away from doors,
windows, vents, heaters, and outside walls that could affect temperature readings. The sensor
should be at least four feet from the floor, and no higher than necessary to prevent tampering.
Mounting
1.
Insert a screwdriver into the gap in the plastic on the bottom
side of the sensor enclosure, and pry the front part of the
enclosure away from the rear mounting plate. Pull the front
away from the mounting plate until the top separates from the
mounting plate.
2.
Remove the punch out above the wiring connector so that the
sensor cable can be run into the sensor enclosure (see Figure
1).
3.
Use the pre-made holes to mount the plate on a junction box
using the screws provided, or mount it against a wall or riser.
Do not mount the plate upside down or sideways. The plate
should be mounted with the terminal block toward the bottom.
4.
If necessary, drill or cut a hole in the wall to allow the sensor
cable to be run through the wall into the sensor's terminal
block.
