selectable with a 4-20 mA, 0-5 VDC, or 0-10 VDC output
signal that is equivalent to 0 to 100% RH. All units are
shipped from the factory set to 4-20 mA output. This
sensor is designed for use with electronic controllers in
commercial heating
management systems.
include an optional 10k-CP (Type II) or 3k Ohm
temperature sensor for monitoring the space
temperature.
For optimal readings, follow these tips:
• Do not install on external walls.
• 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
Separate the cover from the base. Attach the base
directly to the wall or to a standard 2" x 4" junction box
using the (2) #6-32 x 1" screws provided.
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 - see
FIGURE 2 (p.2).
Refer to the Wiring Instructions (p. 2) to make
necessary connections. After wiring, attach the cover
to the base by snapping the top of the cover on rst
and then the bottom. Tighten the cover down, using
the (2) 1/16" Allen screws located in the bottom of
the housing. A 1/16" Hex driver is needed to secure
the cover to the base.
