1 Notes on the documentation
General Information
The domestic ventilation unit consists of a central ventilation appliance for air exchange with heat recovery and
a remote control. For summer operation, you can obtain
a bypass as accessory. It can directly provide living
rooms with cool external air whenever it is necessary.
The external air flow bypasses the heat exchanger.
The unit is connected to an air ducting system, which is
equipped with silencers, pre-filters, fresh-air and exhaust-air grilles and louvres.
Fresh air grilles supply fresh air to the living areas and
stale moist air is extracted from the kitchen, bathroom
and WC.
With the digital remote control the user is able to automatically switch and adapt the domestic ventilation unit
power to their own requirements.
The unit ensures:
– A constant air exchange in the building
– The hygienic minimum air exchange in accordance
with UK building regulations Part F
– Energy savings thanks to high efficiency heat recov-
ery
– A high hygiene standard due to the prevention of hu-
midity and mould damages of the building
The exact model description of the unit is to be found
on the identification plate positioned below the unit.

4.2 Bypass (optional)
The device can be equipped with a bypass, which is fitted on the top of the device, see fig. 4.2.
With a bypass installed the user may operate the socalled "free cooling mode" during the summer months
with the outside temperature falling below room temperature during the night. The cooler outside temperature will not be warmed by the device before it was
blown into the room. To protect the bypass valve from
dirt, we recommend an outside air filter of the filter
class at least G3. The filter is installed on site into the
outside air duct, possibly close to the air inlet.
