91Operating and maintenance instructions for the ventilation unit
Oce usage mode
If the ventilation unit is used in
business premises or in a public
space, its operating mode is likely
to be Oce.
Oce usage modes are:
• Oce (during normal working hours)
• Overtime (when people are present outside normal
working hours)
• Boosting (when additional ventilation is needed)
When the ventilation is operating in Oce mode, the
center circle on the control panel main page displays the
At oce symbol.
Oce mode means that the ventilation unit is often
programmed to function only when there are people at
the premises. Other times the center circle of the control
panel says “Stop”.

operation, you can switch on the Overtime mode.
To activate the Overtime mode:
1. Tap the green circle in the middle of the main page
of the control panel.
