6.2.2. Operating modes and functions
Eco-Mode
Operating in pairs, the units change airfl ow
direction every 50-70 seconds dependent on
the selected fan speed, ensuring heat reco-
very.
Full-blast mode
The system runs in just one direction,
allowing a room to be thoroughly ventilated.
Heat recovery is not available in this mode.
Automatic mode
When running in automatic mode, the inte-
grated humidity sensor automatically deter-
mines fan speed.
Sleep mode
The system stops working for one hour, gi-
ving a room's occupants suffi cient time to
get to sleep. Once the selected duration is
over, the system will continue in the pre-
viously activated mode.
Filter change display
An integrated meter is used to determine
when a fi lter change is needed. This is cal-
culated on the basis of the airfl ow volumes.
When the fi lter needs changing, the fi lter
change LED starts blinking. Once it has been
changed, just press the button to reset the
meter.
The optimal time for changing a fi l-
ter is dependent on local conditions
and can thus vary.
