Operating instructions
Air Humidity Controller
Item no. 1170728
Intended use
The air humidity control measures the humidity via an integrated sensor. A load connected to the
front socket of the air humidity controller can be switched on or off when the air humidity exceeds
a defined value or falls below it.
E.g. an air humidifier (if the ambient air is too dry) or an air dehumidifier (if the air humidity is too
high) that does not have its own air humidity control can be connected to this controller.
For safety and approval purposes (CE), you must not rebuild and/or modify this product. If you

Safety instructions
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information on proper
handling in this manual, we assume no liability for any resulting personal injury or
damage to property. Such cases will invalidate the warranty/guarantee.
• The product is designed in accordance with protection class I. Only a standard
mains socket (with protective earth) for the public supplygrid may be used as a
power source.
• The product is not a toy and must be kept out of the reach of children! There is the
risk of a fatal electric shock!
• Do not leave packing materials unattended. They may become dangerous playthings
for children.
• The product is used to control a connected load depending on the air humidity.
However, the product must not get wet or damp; that poses a danger to life through
electric shock! It must be used in dry interior spaces only!
• Protect the product from extreme temperatures, direct sunlight, strong jolts, high
humidity, moisture, flammable gases, vapours and solvents.
• The mains outlet must be located near to the device and be easily accessible.
• Only connect to a normal mains socket connected to the public supply. Before
plugging in the product, check whether the voltage stated on the product complies
with the voltage of your electricity supplier.
• Never touch the product, or the mains plug, with wet or damp hands when trying to
connect a plug to the front socket. There is a risk of a lethal electric shock! The same
applies to the humidity control itself.
• Never pull out a mains plug by pulling on its cable when disconnecting it from the
front socket of the humidity controller. Always pull the plug out of the front socket by
gripping the area provided for this purpose on its sides.
• Do not use the humidity controller in rooms or under adverse ambient conditions
where combustible gases, vapours or dust are or may be present! There is a risk
of explosion!
• Do not overload the product (take note of the input power in the technical data at the
end of the operating manual!).
• The product must not be exposed to extreme temperatures, strong vibrations or
heavy mechanical stress.
• Only use the product is when it has been securely mounted.
• If you have reason to assume that safe operation is no longer possible, disconnect
the product immediately and secure it against accidental operation. Let an expert
check the product.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height
can damage the product.
• If it is no longer possible to operate the product safely, take it out of operation and
protect it from any accidental use. Safe operation can no longer be guaranteed if
the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• If the product casing is damaged, do not use the product anymore! When it is
connected to the mains, do not touch the humidity controller or the connected
device! First switch off at the mains socket to which the humidity controller is
connected (switch off the circuit breaker).
Disconnect any device that is connected to the humidity control; then unplug the
humidity control from the mains socket. Take the product to a specialist workshop or
dispose of it in an environmentally friendly way.
• In commercial institutions, the accident prevention regulations of the employer’s
liability insurance association for electrical systems and operating facilities are to
be observed!
• The rechargeable battery is permanently built into the product and cannot be
replaced.
• Never damage the rechargeable battery. Damaging the casing of the rechargeable
battery might cause an explosion or a fire!
• Never short-circuit the contacts of the rechargeable battery. Do not throw the
battery or the product into fire. There is a danger of fire and explosion!
• Consult an expert when in doubt about operation, safety or connection of the device.
•
Maintenance, modifications and repairs are to be performed exclusively by an
expert or at a qualified shop.
• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.
Initial start-up, recharging the integrated accumulator
Ensure that the display is pointing upwards when plugging the product into the mains.
• The air humidity controller features a built-in NiMH rechargeable battery/accumulator. The
accumulator serves to prevent data loss in the event of a power failure.
Furthermore, the humidity control (with fully charged accumulator) can be programmed
even if it is not connected to a mains socket.
The accumulator is fully charged if the humidity control has been connected to the
mains voltage for approx. 12 hours.
• At delivery, the NiMH battery is usually empty. Nothing is shown in the display. In order to
perform the programming, connect the humidity control to a mains socket. Shortly after, the
display will be activated and you can start up the humidity controller.
Choose operating mode
If the NiMH accumulator integrated in the humidity control is charged, the programming
can be performed even though the humidy control is not connected to the mains
socket. If the display does not work, the NiMH accumulator is empty. In this case, plug
the humidity controller into a mains socket to perform the programming.
If “SET” is shown at the display’s top right-hand side, press the
“
“, button briefly in order for the humidity control to change
to the setting mode for the corresponding operating mode; see
illustration to the right.
Now the display shows the currently measured air humidity at the
bottom left and the currently selected operating mode at the top.
a) Operating mode 1
Display “
“ = Air humidification: a load is switched on if the humidity in the room falls
below a preset value.
This operating mode must be selected if you have connected an air humidifier.
b) Operating mode 2
Display “
“ = Air dehumidification: a load is switched on if the humidity in the room
exceeds a preset value.
This operating mode must be selected if you have connected an air dehumidifier or a
ventilation system.
c) To change the operating mode, proceed as follows
• Press and hold the „ “ key (do not release).
• In addition, press and hold the „ “ key.
• After approx. 2 to 3 seconds the operating mode changes. Now release both buttons.
Setting the switching threshold
•
Briefly press the “
“ button. The display indicates “RH SET”
in the top row; see illustration to the right.
The current room humidity is indicated on the bottom left; and
the currently set switching threshold on the bottom right.
• Set the switching threshold using the “ “ or “
“ button. The display “SET” will flash. For a
quick adjustment hold the corresponding button for a longer period of time.
• If you do not press any key for several seconds, the setting mode will be exited and the display
“SET” stops blinking. The new switching threshold is now saved.
Connecting a load
•
Plug the mains plug of the load (air humidifier, air dehumidifier, ventilationsystem or the like) into
the mains socket at the front of the humidity control.
• Pay attention to the max. connection values of the humidity control; see section “Technical
Data”.
• If you want to disconnect the load, hold the humidity controller and unplug the load’s mains plug
from the mains socket of the humidity controller.
