Custom mode settings

The Custom mode is used in special circumstances, for example, to compensate for temporary negative pressure caused by a fireplace or cooker hood. In such situations, the difference between the supply and extract air flows should not exceed 30%.

You can set a timer and adjust the air flows and supply air temperature in the Custom mode.

To set the Custom mode settings:

  1. Set the supply and extract air flows for the Custom mode and adjust the valves according to the ventilation plan.
  2. You can adjust the supply air temperature setting and disable the humidity and carbon dioxide control.
  3. Set a timer for the Custom mode (optional).
