4. Operation

4.1. Control options

The ventilation unit has several pre-programmed modes. A number
of control switches are available for actively setting the correct
mode/ventilation capacity:
Wireless RF-VI remote control with LED indicator for status and
●
ventilation functions
Wireless RF control switch with three settings and a timer
●
function
Wireless RF control switch with two settings, an automatic
●
setting and a timer function
Conventional wired switch with three settings
●
A combination of the above options.
●
For pairing or unpairing a wireless RF remote control with/from the
unit, consult Pairing and unpairing RF remote controls on page 27
Note
Do not attach wireless control switches to metal surfaces. This
can interfere with the wireless control switch or cause it to stop
working entirely.
Note
The wireless control switches have a range of 100 metres in free
space (no obstacles). The distance at which the switch can
function properly is reduced depending on the obstacles
interfering with the signal.
Note
When using a wireless control switch in the bathroom, it should
not be located in zone 0 (floor of the shower base) or zone 1 (up
to 2.5 metres above the shower base) due to the effects of
moisture.
ä
Caution!
If the fan runs at high speed when low speed is selected or at
low speed when high speed or timer mode is selected, the
ventilation unit is faulty.
See Faults on page 36 for possible causes of problems and
potential solutions.

4.2. RF-VI wireless remote control

This RF-VI wireless remote control always displays the status of the
ventilation unit with which it is paired.
The three-colour LED (Status) on the RF-VI indicates the status of
the ventilation unit.
Red (continuously blinking once per second) = RF-VI not paired
●
Red (continuously blinking in error code pattern) = Ventilation
●
unit is reporting an error (see error code table in the RF-VI
manual)
Orange (continuously on) = Dirty filter
●
Green (continuously on) = No errors, filter okay (everything in
●
order)
White (continuously blinking once per second) = The RF-VI is
●
paired but has not been in communication with the ventilation
unit for one hour
If you press and hold the touch button for 10 to 12 seconds
normal operation (until the three-colour LED flashes orange), the
RF-VI sends a "Reset dirty filter" message (3 times).
*
If the button is held for longer than 12 seconds, the three-colour LED will go
dark and nothing will happen.
The user can switch between ventilation modes by pressing the
touch button. Each time it is pressed, the mode switches to the next
one in the cyclical order shown below. The corresponding LED is lit
(green).
