7 Design and operating logic
The warm, used exhaust air enters the
ventilation system from the room, is
cleaned in the exhaust air filter and
flows through the heat exchanger. It is
then led outdoors by the exhaust air
fan via the exhaust air pipe.
The fresh outside air flows into the
ventilation system and is cleaned in
the supply air filter. The air then
continues to flow through the heat
exchanger and is led into the room by the supply air fan.
In the heat exchanger, the heat from the warm extract air is
transferred to the cold outside air. Here, the two air flows are
completely separated from each other.
15
Manual –AlphaFreshbox 200 WiFi
The heat recovery minimises heat loss in the cold season and
thus saves heating costs.
The unit is equipped with a recirculation damper. In
recirculation mode, it is open and the supply and extract air
dampers are closed.
The stale exhaust air flows through
the filters, is cleaned again, and is
then fed further into the room
through a heat exchanger.
Depending on the model, the
ventilation system is equipped with a
pre-heating or post-heating coil. This
provides automatic protection
against overheating of the heating
coil.
AlphaFreshbox 200 WiFi is equipped with a pre-heating coil. If
the supply air temperature is below -3 °C, the pre-heating coil
automatically heats the supply air so that the average
temperature of the extract air downstream of the heat
exchanger is not below +5 °C. The extract air fan runs on the
heating coil.
The extract air fan runs at the maximum ventilation level. No
condensate forms in the ventilation system with enthalpy heat
exchanger because the humidity of the extract air is
transferred to the supply air via the enthalpy membrane. The
shutters open automatically when the fan motors are switched
on and close when they are switched off.
16
Manual –AlphaFreshbox 200 WiFi
It is possible to
connect an additional
exhaust air spigot (Ø
100 mm) for the
removal of air from
other rooms, for
example the
bathroom. The
connection piece is included in the scope of delivery.
The exhaust air grille must be closed with the magnetic plug
included in the scope of delivery (see "Installation and
preparation for operation").

Use the template to mark the holes for the ventilation
pipes, the attachment of the unit and the outlet of the
power cable. Lay all cables and pipes to the installation
site before starting the installation work.
2. Remove the template and drill two core holes for the
ventilation pipes with a diameter of 120 mm.
19
Manual –AlphaFreshbox 200 WiFi
When installing the ventilation system with a two-room
connection, prepare a hole for the connection bend and
the laying of the ventilation pipe in the wall. The
connection bend and the ventilation pipes are available as
accessories.
Drill the holes with a diameter of 8 mm and a depth of 90
mm. Insert the dowels. Remove the perforated fields for
the ventilation pipes from the template and reattach the
template with the adhesive tape.
3. Cut the ventilation pipes to the required length: On the
outside wall, the ventilation pipe must protrude by the
length required for mounting the outside ventilation
bonnet (A). For details, see the installation instructions for
the ventilation bonnet.
The external bonnet is not included in the scope of
delivery of the ventilation system and is available as an
optional accessory.
