terminal for 5 seconds (“STOP” appears on the screen). Remember to turn off the fuses when servicing. If the
ventilation unit has a water battery you may open the doors after 1 minute (if fans have stopped). If the unit
has an electrical battery you must wait for 3 minutes (el.battery must cool down and the fans must stop).
The speed of the unit at the normal stage must be set to the voltage specified in the
Documentation of Ventilation
Data form that is enclosed with the ventilation drawings from the company responsible for project planning. Locate
the adjustment switch (refer to ventilation unit dokumentation).
Set the switch to the desired position for each fan.
It is possible to choose on the switch between factory setting, lowest setting (-) or highest s), see Fig. 1. To
achieve more adjustment ranges, it is necessary to switch over directly on the transformer.
