7.3 Ventilation levels factory setting
Supply air ( blue potentiometer adjusters)
Exhaust air ( red potentiometer adjusters)
7.3.1 Extended setting range for each
ventilation level
The volumetric flow settings for each ventila-
tion level are permanently specified as part of
the factory setting (jumpers 1, 2 and 3 open

Chapter 6.7.3)

"S" potentiometer.
Alternatively, the volumetric flows can be
adjusted in the extended setting range for
each ventilation level separately (setting
range 40....160 m³/h, control voltage for fans
at each ventilation level freely adjustable from
1.7...10 V).
Jumpers 1 + 2 must be bridged and jumper 3
must be open for the extended setting range.
The control voltage measurement process is
described in the next chapter "Volumetric flow
setting with voltmeter".
NOTICE
Use a suitable measuring
instrument when measuring
the control voltages.

7.4 Volumetric flow setting with
voltmeter
Alternatively, the volumetric flows for the
individual ventilation levels can be adjusted
using a voltmeter.
