Description of operating modes
Continuous basic ventilation (basic airflow)
The fan operates at a constant low speed, 40 m
3
/h,
creating a useful basic ventilation. Intellisense i7 has a
self-calibrating motor that prevents backdraughts.
Presence sensor – motion (IR) and light
The presence sensor is activated by motion (IR) or when
the lighting is switched on. Over run time 15 minutes.
The fan switches to a medium speed, 60 m
3
/h, and
depending on the choice of mode, it starts up:
– directly (mode 1, 2 and 6)
– after a 2.5 minute on-delay (mode 4)
Automatic humidity control
A self-adjusting humidity sensor continuously measures
the humidity level in the room. The fan starts up automat-
ically if the humidity level rises rapidly (e.g. in the case of
a shower) or if the relative humidity (RH) exceeds 70%.
When the humidity level is restored, the fan returns to
the basic flow or stops.
Depending on the choice of mode, the fan will operate at:
– High speed 95 m
3
/h (mode 1, 3, 4, 6, 8 and 9)
– Maximum speed 110 m
3
/h (mode 2)
Manual start and stop by use of a switch
The fan may be connected for manual start via a separate
light/power switch. When the switch is turned on, the fan
will start up and run at high speed, 95 m
3
/h. When the
switch is turned off, the fan will stop.
Airing function
If the humidity control or presence sensor has not been
active for 24 hours, the airing function will start up. The fan
will operate at medium speed for 30 minutes every 12 hours.
Heat Mover, thermostat
The fan will start at 28°C and move the surplus heat to
adjacent rooms. The fan turns off at 24°C. Airflow 95 m
3
/h.
