Fault
Possible cause
Remedy
After being connected to power
supply, the fan does not rotate or
respond to control in any way.
No power supply is connected.
Call a specialist.
There is a fault in the internal joints
of the device.
The air flow is low.
The ventilation system is clogged.
Clean the ventilation system.
Increased noise or vibration.
The fan is not properly attached or
is installed incorrectly.
Remove the mistake during
installation.
The ventilation system is clogged.
Clean the ventilation system.

MODE 4
– light sensor (on), humidity sensor, time r separate switch
Wire connection:
Connect the brown phase wire to the L terminal, the black switching wire to the T terminal and the
blue neutral wire to the N terminal. Place the I/II jumper as seen in PIC 6a. Set the A/B jumper to the position of PIC 1a.
The fan starts when the light is on (it must be on for at least 45 seconds) and it will be ventilating throughout the entire
lighting period. After turning the light off, the fan runs down according to the timer setting ("Time"). The humidity sensor
will start the fan based on the set value ("Humidity") – whether it is light or dark. After the humidity decreases, the fan
continues ventilating for the remaining time set on the timer. The fan can be started manually using the switch and it is
ventilating throughout the time set on the timer. If the light is on and the fan is manually switched off using the switch,
the light sensor appears in a paused state – to activate it, repeat the cycle (turn off / turn on).
Note: If the light is turned off earlier (i.e., it has not been on for at least 45 seconds), the fan will not start.
MODE 5
– light sensor (off), humidity sensor, time rundown
Wire connection:
Connect the brown phase wire to the L terminal and the blue neutral wire to the N terminal. Place the
I/II jumper as seen in PIC 6b. Set the A/B jumper to the position of PIC 1b.
The fan starts after the light has been turned off (it must have been on for at least 90 seconds) and it will be ventilating
throughout the entire time set on the timer ("Time"). The humidity sensor will start the fan based on the set value
("Humidity") – it must be dark. After the humidity decreases, the fan continues ventilating for the remaining time set on
the timer.
Note: If the light is turned off earlier (i.e., it has not been on for at least 90 seconds), the fan will not start after turning the
light off.
MODE 6
– light sensor (off), humidity sensor, time r separate switch
Wire connection:
Connect the brown phase wire to the L terminal, the black switching wire to the T terminal and the
blue neutral wire to the N terminal. Place the I/II jumper as seen in PIC 6b. Set the A/B jumper to the position of PIC 1b.
The fan starts after the light has been turned off (it must have been on for at least 90 seconds) and it will be ventilating
throughout the entire time set on the timer ("Time"). The humidity sensor will start the fan based on the set value
("Humidity") – it must be dark. After the humidity decreases, the fan continues ventilating for the remaining time set on
the timer. The fan can be started manually using the switch and it is ventilating throughout the time set on the timer – it
works even with the light on.
Note: If the light is turned off earlier (i.e., it has not been on for at least 90 seconds), the fan will not start after turning the
light off.
TROUBLESHOOTING
MAINTENANCE
Only perform maintenance on the fan when disconnected from the mains! Conduct maintenance at least once a year.
After removing the fan, clean it with a soft rag dampened with a mild solution of water and detergent. Be careful not to
wet down electrical parts of the fan, especially the motor. Wipe the fan dry and return to its installed position.
