Schneider Electric 2232-053 Installation Instructions
APPLICATION
The 2232-053 Room Humidity Transmitter is designed to
measure room humidity over a 30 to 80% R.H. span, and
transmit a proportional 3 to 15 psig signal to controlling and
indicating devices such as receiver-controllers, receiver
gauges and sensitive pressure switches.
This device is a one-pipe, force balanced transmitter which
ires an external restrictor in the supply line. It
requ
incorporates a highly sensitive hygroscopic nylon element
and a ball valve for pneumatic feedback which ensures
accuracy and stability over the entire operating range. All
internal parts are corrosion resistant, and there is an internal
filter to maintain cleanliness of operating parts.

*Other rough-in hardware and installation fittings must be ordered
separately.
GENERAL INSTRUCTIONS
1. Transmitter should be mounted where it will be affected only by average room humidity. Free circulation of air must exist at mounting location. Avoid locations that are affected by drafts, radiant heat, water pipes, air ducts, etc.
2. Avoid outside wall locations. When this location is
fied, use 20-716 Insulating Backplate.
speci
3. Mount Transmitter only after wall surface has been finished. Allow the device time to reach ambient conditions before calibrating.
4. Receiver gauge must be 3-15 psig range and graduated 30-80% R.H. to match transmitter output.
5. The nylon hygroscopic element must be kept clean. Do not touch with fingers or other foreign objects.
Installation
• Tools (not provided):
– Appropriate screwdriver for mounting the thermostat
– 20-881 Thermostat calibration and cover screw

Connect to Thermostat
1. Assemble the eyelets and two tube couplers to tubing.
2. Connect the assembly by inserting the tube coupler into
isting tubing in the wall (Figure-1).

3. Pull tubing through center hole in mounting plate and screw
mounting plate to wall with flat head screws. Cut tubing. The
tubing is connected into the port on the thermostat (Figure-1).
4. Affix thermostat to mounting ring with round head screws,
taking care not to kink the tubing.
CALIBRATION
After mounting, check calibration. Calibration is accomplished by
turning calibrating screw (1) clockwise to decrease branch
pressure or counterclockwise to increase the branch pressure. DO
NOT TOUCH THE HYGROSCOPIC ELEMENT!
