MENU – Installer menu:
The basic unit functions can be adjusted in the installer menu, e.g. the adaptation of
fan stages to
the building.
Adaptation of individual fan stages
All four fan stages can be individually adjusted for each fan and
thus adapted to the requirements of
the building.
The fan stages are adjusted by the control voltage in the range of 1.7 V to 10V in steps of 0.1 V.
Stage 1
Factory setting: Supply/extract air fan in stage 1 = 3.0V
ATTENTION: This basic setting must be adapted to the actual airflow rates
as part of the
adjustment of the ventilation unit.
Stage 2
Factory setting: Supply/extract air fan in stage 2 = 6.0V
ATTENTION: This basic setting must be adapted to the actual airflow rates as part of the
adjustment of the ventilation unit.
Stage 3
Factory setting: Supply/extract air fan in stage 3 = 7.5V
ATTENTION: This basic setting must be adapted to the actual airflow rates as part of the
adjustment of the ventilation unit.
Stage 4
Factory setting: Supply/extract air fan in stage 4 = 9.0V
ATTENTION: This basic setting must be adapted to the actual airflow rates as part of the
adjustment of the ventilation unit.
Minimum fan stage
In order to avoid building damage and
to ensure the air exchange necessary for hygiene purposes,
the ventilation unit should be operated continuously at the lowest stage (Factory setting: Stage 1)
Adjust „Minimum fan stage 1” or „Minimum fan stage 0” via rotary encoder.
Stage 0 = Switch-off function can be activated
Stage 1 = Switch-off function cannot be activated (min. FS 1)
ATTENTION: Changing the factory settings can lead to mould formation and
thus to building
damage and personal injury!
