Overview of adjustable functions

The programme mode enables the individual adjustment of the ventilation system, numerous functions can be confi-
gured:
Configuration
Filter change
Function External contact
Unit assignment
Supply air mode
Minimum ventilation stage If the "Unit standby" function is selected, the fans can be deactivated via
Distribution ratio
Description
Setting the interval times for the filter change display.
Four filter intervals can be selected (3, 6, 9 ,12 months).
The external contact is assigned a function, which is activated when the
contact is closed.
a) Cross ventilation
The ventilation units run continuously in supply air or extract air mode cor-
responding to their configuration as a supply air unit (terminal 10) or
extract air unit (terminal 11). This operating mode involves permanent
cross ventilation and there is no heat recovery.
b) Supply air mode
The units selected when setting the supply air mode unit assignment run
continuously in supply air mode. In this operating mode, extract air is not
removed by the ventilation units.
c) Unit standby
All ventilation units are in standby mode (fan off).
d) Max. ventilation stage
All ventilation units are operated at max. ventilation stage.
a) Only supply air units (terminal 10):
When the operating mode supply air is selected or when supply air mode
is activated by the external contact, only the supply air units will operate
in supply air mode. The extract air units will be switched off.
b) All units:
When the operating mode supply air is manually selected or when supply
air mode is activated by the external contact, all units will operate in sup-
ply air mode.
the ventilation stage button. With regard to "ventilation stage 1", the
deactivation of the fans is not possible.
Distribution ratio (number of supply air units: extract air units)
Definition:
Units connected to terminal 10 start in supply air mode.
Units connected to terminal 11 start in extract air mode.
In order to ensure a balanced air volume flow through the ventilation units
with an uneven number of units, the volume flow of the extract air units
are reduced corresponding to the distribution ratio. This adjustment
applies eqully for all ventilation stages.
a) 1:1 (2:2, 3:3, 4:4)
The volume flows of the (individual) extract air units and supply air units
are the same.
b) 1:2 (2:4)
The volume flows of the (individual) extract air units and supply air units
are in the ratio 1:2, i.e. an extract air unit delivers 50 % of the volume flow
of a supply air unit.
c) 2:3
The volume flows of the (individual) extract air units and supply air units
are in the ratio 2:3, i.e. an extract air unit delivers 66.6 % of the volume
flow of a supply air unit.
d) 3:4
The volume flows of the (individual) extract air units and supply air units
are in the ratio 3:4, i.e. an extract air unit delivers 75 % of the volume flow
of a supply air unit.
e) 3:5
The volume flows of the (individual) extract air units and supply air units
are in the ratio 3:5, i.e. an extract air unit delivers 60 % of the volume flow
of a supply air unit.
