ELECTRONIC HUMIDITY

TRANSMITTER: H100

DESCRIPTION

The H100 series low voltage, microcomputer-based PI
(proportional and integral) humidity transmitters are
designed for accurate humidity and/or dehumidification
control in non-corrosive commercial applications such
as: hospitals, schools, office buildings, retail stores,
museums, computer rooms, etc.

The H100 series is available with 0 to 5 Vdc or 10 Vdc
output signal.

Each transmitter is computer calibrated and factory
programmed with default parameters.

CALIBRATION OF TRANSMITTER

The transmitter is factory calibrated. However, it can be field recalibrated by using the ( -10%, 0%, +10% )
potentiometer inside the transmitter to adjust the zero (see page 2 for location). The transmitter is already factory
calibrated to the center of the potentiometer. To recalibrate the transmitter to the factory preset, return the
potentiometer to the 0% adjustment.

To calibrate, read the humidity with a precision hygrometer. If the reading is lower than the value you get from the
sensor, remove transmitter from the base, turn the potentiometer by the amount of error in the negative scale. If the
value is higher, turn the potentiometer in the positive scale. We recommend that you don’t try to adjust the two
potentiometers on the sensor unless you have access to two points of calibration. If you really need to recalibrate the
sensor, please return the transmitter to the factory.

H50 Internal humidity sensor for H100 transmitter and for H80 remote wall sensor.

H60 Duct humidity sensor to mount directly onto the back of any H100 transmitter.

H71 Duct humidity sensor to mount directly onto the supply or return of the ventilation duct.

H80 Wall humidity sensor to mount in any remote location.

008-0089 Replacement lexan (cover sticker) for H100 transmitter

024-0048 Transmitter replacement base with connector (H50 internal humidity sensor not included).

H50 INTERNAL SENSOR H60 DUCT SENSOR

This humidity sensor can be
mounted directly on 024-0048
transmitter base.

H71 REMOTE DUCT SENSOR H80 REMOTE WALL SENSOR

This humidity sensor can be
mounted directly onto the back of
any H100 transmitter, with the
supplied hardware. This
transforms the transmitter into a
duct-mounted transmitter.

WARNING:

Where failure or malfunction of
H100 series transmitters could
lead to an abnormal operating
condition that could cause
personal injury or damage to the
equipment or other property,
other devices (limit or safety
controls) or systems (alarm or
supervisory) intended to warn of,
or protect against, failure or
malfunction of H100 transmitters
must be incorporated into and
maintained as part of the control
system.

LOCATION OF CALIBRATION

POTENTIOMETER

This humidity sensor can be
mounted directly onto the supply
or return of the ventilation duct.
The H100 may be located on the
wall with humidity sensing from
the remote H71 sensor location.

This humidity sensor can be wall
mounted in any remote location.
The transmitter may be located
on the duct or other location, with
humidity sensing from the H80
sensor location.
