WALL PLATE HUMIDITY
SERIES
Installation & Operation Instructions
GENERAL INFORMATION
The A/RH Wall Plate Series is a Relative Humidity
transmitter that can be powered with either an AC or
DC supply voltage. The RH Wall Plate transmitter is
eld selectable with 0-5 VDC or 0-10 VDC output
signal that is equivalent to 0 to 100% RH. This sensor is
designed for use with electronic controllers in
commercial heating and cooling building manage-
ment systems. The transmitter can also include an
optional temperature sensor for monitoring the space
temperature.
For optimal readings, follow these tips:
• Do not install on external walls.
• Do not install near heat sources. eg: lamps, radiators,
direct sunlight, copiers, chimney walls, walls
concealing hot-water pipes.
• Avoid air registers, di users, vents, and windows.
• Avoid con ned areas such as shelves, closed
cabinets, closets, and behind curtains.
• Eliminate and seal all wall and conduit penetrations. Air
migration from wall cavities may alter temperature
readings.
MOUNTING INSTRUCTIONS
Take care when mounting. Check local code for
mounting height requirements. Typical mounting
heights are 48-60" (1.2 - 1.5 m) o the ground and at
least 1.5' (0.5 m) from the adjacent wall. The sensor
should be mounted in an area where air circulation is
well mixed and not blocked by obstructions.
RH Wall Plates include a Black Rubber Cap that ts
over the sensor lter. This cap should be placed on
the sensor lter during wet/wash down processes.
The cap must be removed for normal operation.
Plate temperature sensors (optional) are mounted on
the back of a 1 Gang stainless steel plate. The foam
pad will insulate the sensor from any drafts in the
wall. There are (2) 6-32 x 3/4" machine screws
provided for junction box mounting. Remove plastic
lm o stainless steel cover.
