C C a a u u t t i i o o n n ! ! Read and understand the instruction before using the product.
C C a a u u t t i i o o n n ! ! Ensure that the installation complies with local safety
regulations.
W W a a r r n n i i n n g g ! ! Before installation or maintenance, the power supply must first
be disconnected in order to prevent potentially lethal electric shocks! In-
stallation or maintenance of this unit should only be carried out by quali-
fied personnel. The manufacturer is not responsible for any eventual
damage or injury caused by inadequate skills during installation, or through
removal of or deactivation of any security devices.
Function
The humidistat uses human hair as the sensor medium.The hair stretches
as the humidity increases and shrinks as the humidity decreases. These
changes are transmitted to a micro switch (two switches). The setpoint
switch affects the position of the micro switches in relation to the hair
element.
The setpoint can be set at between 10% and 95% RH. As the contacts
are of the changeover type the humidistat can control both
humidification and dehumidification. This tried and trusted construction
with few movable parts gives a high degree of reliability and accuracy.
1 step humidistat for 10A
HR1-DH is specially designed to control dehumidifying units and
manage rated currents up to 10A. The humidistat has a closing contact
which activates when the humidity begins to increase.
2 step humidistat
This model has two micro switches. The step differential between them
can be set by means of an adjustment screw.
As the contacts are of the change-over type, the humidistat can control
both humidification and dehumidification.
Calibration
The humidistats are calibrated at the factory before delivery to the
customer, but should be precision calibrated after installation to ensure
optimal results. After this, annual checks and re-calibration are
recommended.
Maintenance
The hair element should be dusted off with a soft brush once a year. Do
not rinse the hair element in water as this changes the calibration point.
For more information concerning maintenance, see instructions supplied
on delivery.
Typical applications
Can be used to control a humidifier or a dehumidifier or for on/off
controlling of a fan. Can also be used to alarm when the humidity
exceeds or falls below a preset level.
