FAQ & Troubleshooting
Q:
How do I know the system is operating?
A:
Due to its quiet operation it is difficult to hear the unit running.
The system may also run in natural ventilation mode depending on
conditions. A simple check is to press the boost button so that boost
mode is initiated. When boost is active the button graphic will change.
This will result in the valve switching into living space ventilation mode
and cause the ventilator start running in power mode. When in boost
mode you should be able to notice that air is being extracted from the
living space when standing next to the ceiling grille.
The operating mode can also be checked on the user interface panel.
