Task and function
The ventilation system is used to aerate and ventilate frost-free rooms. It can
be used in private areas (living rooms, bedrooms, kitchens, showers,
bathrooms, storage rooms) or semi-public areas (offices, hotel rooms, daycare
centres, nursing homes).
Used, warm room air is extracted as exhaust air and discharged to the outside
as outgoing air. At the same time, fresh outside air is drawn in and introduced
into the rooms as filtered supply air.
The ventilation system has a position sensor. The position sensor detects
when the ventilation system is not in the correct position in the ventilation
profile. In this case, it blocks operation of the ventilation system.
The ventilation system has the following operating modes:
•a manual mode
•a standby mode
•an automatic mode.
In automatic mode, the speed of the fans is controlled according to the
humidity. In manual mode, the speed of the fans is controlled according to the
set power level.
The ventilation system has one button and six RGB LEDs. It can also be
equipped and controlled with an external button as an option.
In addition, the ventilation system can also be controlled over a WLAN. WLAN
control is carried out using the GEALAN Home app.
The LEDs indicate the current state of the ventilation system, filter change and
errors. When the ventilation system is in operation, the LEDs switch on
automatically. They switch off after two minutes by default. LED switch-off can
be set in the GEALAN Home app.
Power-saving mode
When the ventilation unit is in standby mode and the set time to LED switch-
off has elapsed, the ventilation unit starts power-saving mode. Power-saving
mode is not displayed separately. Access to the ventilation system through the
GEALAN Home app is still possible. The power-saving mode is automatically
ended as soon as the ventilation system is operated or the LED switch-off is
disabled.

Description

Frost protection monitoring
The ventilation system has frost protection monitoring. Frost protection
monitoring prevents freezing of and thus damage to the heat exchanger. Frost
protection monitoring is active in all operating modes.
The heat exchanger’s exhaust air duct may start to freeze due to condensate
formation and sub-zero outdoor temperatures. So the exhaust air duct’s cross-
section through the heat exchanger is continuously reduced. As a result, less
heat is transferred to the supply air. This causes a significant drop in supply air
temperature.
The system continuously monitors the supply air temperature. As soon as the
supply air temperature drops too low, the system automatically switches to
frost protection mode.
The supply air fan is switched off in frost protection mode. The exhaust air fan
runs continuously at level 2. It ensures defrosting and drying of the heat
exchanger.
The frost protection ends automatically as soon as the danger to the heat
exchanger has passed. Once frost protection has ended, the ventilation unit
continues to run in the operating mode that was active previously.
Filters
The ventilation unit has two filters for supply air and exhaust air. The filters
have a limited service life and have to be changed regularly. The filters’
service life depends on the volume of air that passes through them and is
therefore dependent on the ventilation unit’s operating mode.
The filters have their own data memory. The operating hours and the running
time are stored in this data memory depending on the operating mode.
When the service life of one or both of the filters is almost reached (after 11
months in level 1), ‘Filter change necessary’ is indicated. However, the
ventilation unit continues to operate normally.
When the service life of one or both of the filters is finally reached (after a total
of 13 months in level 1), ‘Filter change mandatory’ is indicated. The ventilation
unit can no longer operate.
‘Filter change necessary’ and ‘Filter change mandatory’ are indicated by
orange LEDs (see page 10 regarding this matter). The LED closest to the filter
to be changed is displayed slightly darker than the other LEDs. This informs
you which filter needs to be replaced.
Once the filters have been changed, the LED indicator goes out and the
ventilation unit automatically continues in the last operating mode.
Cover for closing the air ducts
A cover is fitted over the fans (under the cover strip). This cover allows the
airways to be closed. Both of the ventilation unit’s fans switch off when the

Description

The six characters (without dots) are taken from the MAC address on the
name plate.
The SoftAP mode is secured with a password. The password is made up of
your ventilation system’s serial number (SN) and as many zeros as necessary
to reach 12 digits including the serial number (SN). For example, the serial
number (SN) 158329 results in the password ‘SN0000158329’. The length of
the serial number may vary.
The serial number (SN) is attached to the ventilation unit. If the sticker was
removed by mistake, you can ask your specialist dealer for the serial number
with the WLAN SSID. For security reasons, you must change the password
after logging in for the first time. If you forget the password, you must reset all
