INTRODUCTION
This humidity transmitter uses a highly accurate and reliable Thermoset Polymer
based capacitance humidity sensor and state-of-the-art digital linearization and
temperature compensated cicuitry in an attractive, low prole enclosure to
monitor room humidity levels. Additional options are available which include
manual override & LCD display.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning
the humidity transmitter. Failure to follow these instructions may result in
product damage. Do not use in an explosive or hazardous environment, with
combustible or ammable gases, as a safety or emergency stop device or in
any other application where failure of the product could result in personal
injury. Take electrostatic discharge precautions during installation. Do not
exceed the device ratings.
MOUNTING
The humidity sensor installs on a standard electrical box or can be mounted directly to the
wall. The backplate is congured to be compatible with many dierent electrical boxes
types. The humidity transmitter should be mounted ve feet from the oor of the area to
be controlled. Do not mount the sensor near doors, opening windows, supply air diusers
or other known air disturbances. Avoid areas where the sensor is exposed to vibrations or
rapid temperature changes.
Begin by removing the cover. Grasp the bottom of the cover and pull outward from the
backplate as shown in Figure 1. Set cover aside. Do not remove the PCB from the enclosure
base.
Feed at least 6" of wire through the wall and out of the junction box. Feed connection
wires through center hole on backplate and PCB, then secure backplate to electrical box or
wall with suitable screws (not supplied) as shown in Figure 3. The mounting holes in allow
for up/down & side to side movement to compensate for unlevel electrical box installation.
Make wire connections as per the “Wiring illustrations”on Page 2 and re-install decorative
cover by placing the top of the cover into the cover holders on the top of the backplate
and snapping the bottom into place.
Two 1/16”Allen Key set screws are provided on the bottom of enclosure to add security and
lock cover in place. To engage, insert Allen Key and turn counter-clockwise 2-3 rotations.
As seen in Figure 4.

WIRING
• Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment damage.
• Select desired signal output type by placin the output jumper in required position, as shown in Figure 5. Please note that pin connection
tabs in jumper must be in vertical position.
• If voltage output is required, place Voltage Span Jumper to desired span position, as shown in Figure 6. I.E. 10 = 0-10 Vdc.
• Connect the plus dc or ac voltage hot side to the POWER terminal. For voltage output or AC power, the supply common is connected to
the COMMON terminal. The device is reverse voltage protected and will not operate is connected backwards. It has a half-wave power
supply so the supply common is the same as the signal common. See Figure 7.
• The analog output is available on the RH OUTPUT terminal. Check the controller Analog Input to determine the proper connection before
applying power. See Figure 7.
• If installed, the resistance temperature signal is available on the two terminals labeled TEMPERATURE SENSOR. See Figure 8.
