COMPULSORY:
EARTHING
•
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�
CHECK THE POTENTIAL EARTHING!

POWER CONSUMPTION: Use the data on the rating plate of the appliance.
!
Each control panel can only control one device.
ATTENTION: If several devices are connected, it is advisable to design the power supply of the motors / devices inde
-
pendently.

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)
ATTENTION! AT THE SAME INPUT “L” AND “LV” CANNOT BE PHASE,
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�
