INSTRUCTIONS FOR USE
1. Application
The function of the ventilation system is to pro-
duce fresh indoor air and to remove emissions
and moisture from the air. The air in the home
should be changed at a continuous and suf-
ficient rate to ensure a pleasant indoor climate
and avoid damage to building elements caused
by dampness. The ventilation unit should be
stopped only while service work is in progress.
1.1 Commissioning
A qualified person should set the ventilation
unit’s and the ventilation equipment’s airflows
using appropriate measurement equipment.
Sizing curves for fan capacities are available in
the Installation, operation and maintenance
manual. - A Premium control panel is used for
setting the fan speeds for the unit’s fan oper-
ating modes (Away, Home and Boost).
The ventilation unit must not be operated
without filters. Install only filters recommend-
ed by Walter Meier in the ventilation unit.
The ventilation should not be commissioned
until all work that produces large quantities
of grinding dust or other impurities has been
completed.
1.2 Control of the ventilation system
The
Home
fan operating mode corresponds to
normal airflow in the home and the
Boost
fan
operating mode is used while cooking, taking a
sauna bath, drying laundry and the like.
An airflow which is lower than normal situation
airflow can be used when no one is present
in the home. This saves on fan energy and the
home heating system does not have to heat as
much air during the cold season. A lower airflow
can be produced by means of the
Away
fan
operating mode. The user must nevertheless as-
sess whether a low airflow will be sufficient for
removing emissions, moisture from the air.
The ventilation system can be controlled from
a Premium control panel or a Premium cooker
hood.
In multi-storey buildings and terraced homes,
the ventilation unit should preferably be
controlled from a Premium cooker hood. The
caretaker then needs only one control panel for
changing the settings, if required. Therefore no
Premium control panel is included in the basic
supply of S350 ventilation units. In the S350
Duo-models, the control panel and the wall
mounting bracket are standard.

1.2.1 Premium control panel
All the unit functions can be controlled and
the settings can be changed from a Premium
control panel.
When the power is switched on, the ventila-
tion unit starts up in the Home fan operating
mode. It takes approx. one minute for the
system to start up; after that, the control
panel will be operative. Likewise after a power
failure, the ventilation unit will start up in the
Home operating mode if the memory has
been cleared during the power failure.
