10.3 RB 300 factory settings
Supply air (blue potentiometer adjusters)
Exhaust air (red potentiometer adjusters)
Extended setting range for each
ventilation level
The volume flow settings for each ventilation
level are defined by the factory setting
(jumper 1 + 2 open, jumper 3 bridged),
see potentiometer above.
Alternatively, the volume flows can be
adjusted in the extended setting range for
each ventilation level separately (setting
range 80....300 m³/h, control voltage for fans
at each ventilation level freely adjustable from
1.7 ... 10 V).
The control voltage measurement process is
described in the next chapter 10.5 "Volume-
tric flow setting with voltmeter".
Jumper 1 must be bridged and jumper 2 + 3
must be open for the extended setting range.
Use a suitable measuring

instrument when measuring
the control voltages.
