16.1 Basic information: operating modes and fan settings

Depending on the prevailing outside temperature you can choose between two operating modes:
summer or winter. You can also choose between manual and automatic operating mode.
You can choose the power level on the selector switch on the control unit. The control unit is
equipped with a fault alarm system (see operating instructions for the control unit). You can adjust
the air discharge speed of the fans at 5 levels:
Level 1 = min. air discharge speed
Level 5 = max. air discharge speed
In the summer operating mode, only the fans are operating at the selected level. This operating
mode screens the outdoor air and circulates the air inside.
In the winter operating mode, the heating is switched on. The heat exchanger is supplied with hot
water. The air curtain screens the entrance with warm air. The fans are operated even if the
building's heating system is not in operation (operation without heating medium).
In the manual operating mode, the fans are operated permanently at the selected level.
In the automatic operating mode, the fans are put into operation by an external con-tact (e.g. door
contact, room thermostat) at the selected level.

16.2 How to maximize your system's screening capacity

Your air curtain system can only achieve the maximum screening capacity if all functional
components are set correctly. The air curtain system screens a room against cold air and draughts
from outside. In the case of high outside pressure (wind pushes towards the inside) a higher
volume of air (e.g. level 5) should be selected on the controller to counteract the pressure. The
best setting of the air curtain is reached when no more cold air flows into the inside in the lower
section of the door and no more warm air escapes from an area of about 1m in front of the door.
The setting requires a little patience and should be adjusted according to changing weather
conditions. If the temperature of the discharged air is too low, it must be re-adjusted on the
thermostatic valve.
