Standard ventilation is the ventilation
ventilation
necessary to meet hygiene standards
and ensure protection of the building
structure when users are present.
Intensive

Intensive ventilation is ventilation at a
ventilation
higher flow rate to reduce load
peaks, e.g. for rapid ventilation dur-
ing or after a party. You can switch
on intensive ventilation with the pro-
gramming unit or with an optionally
connectible external pushbutton.

Flow rate control
The qualified contractor sets the air flow rate for each fan set-
ting during commissioning. Constant flow rate control ensures
that the air flow rates through the supply air and extract air fans
are achieved irrespective of the duct pressure.
4.3.1 Frost protection
The appliance has a frost protection controller, which ensures
that it works to optimum effect even at low outside temperat-
ures. If the outdoor air temperature falls below the selected
frost protection value, the integral electric preheating coil is
switched on. This prevents the cross-countercurrent heat ex-
changer from freezing up. The integral electric preheating coil is
referred to in these instructions simply as the "preheating coil".
When the preheating coil is active, the "Frost protection" symbol
appears on the display.
Once the output limit of the preheating coil is reached, the ap-
pliance reduces the air flow rate. This means that at low outside
temperatures and high flow rates, the appliance may reduce the
air flow rate.
The frost protection function protects the appliance from frost,
not the building.
4.3.2 Bypass mode
The appliance has an integral bypass damper. The bypass
damper enables filtered fresh air to be supplied without passing
through the cross-countercurrent heat exchanger.
Utilising cool outdoor air
Cool, fresh air is required on summer nights in particular. In
such cases, in automatic mode, as much of the warm air in the
home as possible is displaced by cooler fresh air. This function
is also referred to as passive cooling.
Utilising warm outdoor air
In spring and autumn, the appliance can increase the room
temperature by opening the bypass damper in automatic mode
and drawing warmer outdoor air into the building.
4.3.3 Right-hand/left-hand versions
The appliance offers the option of switching the (extract air/sup-
ply air) ducts on the living space side, with the (exhaust air/out-
door air) ducts on the outdoor air side from right to left.

WLAN
The appliance has an integral WLAN module.
4.4.1 App
Using the app you can pair the WLAN module with your mobile
device.
®
The app is available for iOS
– MyStiebel
Once pairing is completed, you can use the app to control a
number of functions that would normally be controlled with the
ventilation appliance's programming unit.
4.4.2 Conditions
Router requirements
– Supported encryption:
– WPA™ PSK
– WPA2™ PSK
– WPA3™ PSK
– Port 443 must be open
Mobile device requirements
– Check in the Apple App Store
your mobile device meets the requirements specified for the
app.
General requirements
– You accept the app's conditions of use.
– Internet access is available
– Company networks are not supported.
– Do not pair the WLAN module with unsecured or public net-
works.
– Do not use WLAN guest access for the pairing. Some WLAN
networks with guest access do not allow the pairing of
WLAN modules with mobile devices.

Transportation (qualified contract-
ors)
– The appliance casing is not designed to withstand strong
forces.
u If the appliance is transported without packing and without
using a pallet, take care not to damage its outer casing.
u Use the recessed grips on the underside of the appliance.
u Protect the appliance against heavy impact during trans-
port.
6
Installation (qualified contractors)
6.1
Installation site
The discharged cold air can cause condensation to be formed in
the vicinity of the air discharge.
u At low temperatures, ensure that there is no risk of slipping
due to wet conditions or ice formation on adjacent footpaths
and driveways.
The installation site must fulfil the following requirements:
– Free from the risk of frost
