The device works on the principle of air circulation, which blows hot air accumulated in the upper third of the room back into the living
zone, thus reducing heating losses due to air stratification�
The device has a control electronics that allows two control modes� In automatic mode, if the preset temperature (25 ° C at the factory)
reaches the air temperature at the unit, the fan will start and blow down the above warm air� In manual mode, the device can be started
at any time with the help of a switch, so the device can also be used for ventilation and air circulation�
The direction of the blow-out can be set within certain limits using the lamella on the device� It is recommended to use an air technic
specialist to determine the installation location of the device and to set the exact direction of the blow-out�

• Safe operation of the device is only established if it has been connected in accordance with the relevant safety regulations and is
properly earthed�
• When making the connection, make sure that the earth cable is the longest so that it can be the last to break if the connection cable is
tensioned, thus ensuring that the appliance is properly earthed�
When selecting cables, take into account the applied current and the relevant local regulations, and that no voltage drop of more than
3% is permitted on the line�
• Use H05V-K or N07V-K insulated wire that can be used up to 300/500V� All wiring not in the control box must be routed through a pipe
or duct�
• Cables out of the pipe or duct must not be tensioned or twisted� They must be protected from moisture� The remaining wires can only
be used to connect the finishing sections� Make sure all wires are connected properly�
• Make the electrical connection according to the wiring diagram supplied with the device�
• The use of adapters, manifolds and extension cords is not permitted when connecting the main power cord�
• It is the responsibility of the installer to place the device as close as possible to the central power switch!!
• To prevent short circuits, the device must be connected to the mains by installing a multi-pole switch with a minimum opening of 3
mm� (check the current value on the rating plate on the appliance to select the correct switch)� A multi-pole switch is actually a “bi-
polar insulated switch”, meaning the switch is suitable for both voltage and 0-phase disconnection� This means that when the switch
is off, both phases are disconnected� The multi-pole switch or socket must be installed in an easily accessible place�

Connection of the controller
The electrical connection is located next to fuse 5A� Disconnect the plug and
connect the 230V incoming cables to the appropriate connection points�
The connection points are as follows:
PE: potential earthing
N: null
L: phase (230V)
LV: direct input to fan for ventilation (230V)
ONLY ONE CAN BE PHASE!
Optionally, a switch can be used to start the fan regardless of the temperature if
the controller receives a phase at the LV input instead of L� This can be useful,
for example, in summer or when it is necessary to ventilate the room regardless
of the temperature, you can start the fan with a switch and then switch it back
on for temperature-dependent control�
On the vertical auxiliary circuit has a blue potentiometer to control the tempera-
ture at which the fan turns on� It is set at 25 °C at the factory� The temperature
on the knob can be set between 0 and 100 °C�

• Disconnect the device from the mains via the multi-pole switch�
NEVER TUG OR TWIST THE ELECTRIC CABLE!
Never push, pass through, or secure the power cord with a nail or pushpin� A damaged cable can cause a short circuit or physical injury�
APPROPRIATE EXHAUST POSITION-
ING
The device must be positioned so that
the escaping air does not reach people
continuously�
IMPROPER USE CAN CAUSE DAMAGE
The device must not be used in animal
breeders or similar facilities� If necessary,
a special (INOX) design can be solved to
meet such needs�
DO NOT PLACE ANY OBJECTS IN
FRONT OF THE BLOWER
Never place any objects in the way of the
blowers, as this may result in physical
injury or damage to the unit�
Decommissioning
Improper use
DO NOT SIT ON THE DEVICE
DO NOT COVER THE APPLIANCE
WITH ANY OBJECT OR CURTAIN
THAT COULD PREVENT FREE AIR
FLOW.
ATTENTION: When operating the appli-
ance, do not place any objects or clothing
in front of the air outlet, as this may block
the air outlet and damage the appliance�
CLEANING THE APPLIANCE: Do not
spray water on the unit as it may cause
electric shock or damage to the unit� Do
not use hot water, scouring powders or
strong solvents for cleaning� Use a soft
cloth to clean the device�
• This device is made with modern technology, which ensures long-term efficient operation�
• It is important to establish a regular and specific inspection and maintenance program to maintain good condition at all times� The fol-
lowing maintenance program is designed to pay special attention to proper air quality and compliance with installation characteristics�
Service time is highly dependent on adherence to the above� The most aggressive air-side condition occurs when the concentrations
of industrial vapors, salt, chemical vapors, and rising dust in the air are particularly high�
