Description of the indicators on the indoor unit
FILTER
90 days after installation of the cartridge the filter replacement indicator starts glowing. In this
case, clean or replace the filters (see section Maintenance).
After replacement or cleaning of the filters reset the timer using the mobile application or by
pressing and holding the
button on the Master ventilator indoor unit for 5 seconds
until a signal sounds.
ALARM
Alarm indicator.
In case of failure, the Alarm indicator on the indoor unit glows or blinks. Reasons of Alarm
blinking:
•
Battery charge is below the low level.
•
No connection between the Master unit and the router.
•
Alarm shutdown of the ventilator.
If several interconnected ventilators are running in the same network, in case of alarm
shutdown of the ventilator, all of the ventilators of this network also stop. The alarm indicator
blinks on the defective ventilator and glows on the other connected ventilators.
In case of communication loss of the
Master
unit with the router for longer than 20 seconds,
the
Master
unit
switches to
Standby
mode
(Alarm indicator blinking) and the
Slave
units will
signal that there is no communication with the
Master unit
(see the description of the Master
indicator). After resuming communication, the Slave units are automatically synchronised with
the
Master unit
.
MASTER
UNIT
Permanent glowing of the indicator shows the leading unit in the network (Master unit).
Indicator blinking indicates the driven unit (Slave unit) and no connection to the Master unit.
No glowing of the indicator means that this ventilator is a Slave unit and it is connected to a
Master unit.
