Effect
Standard (A0) The only parameters displayed are those that have been re-
leased for the appliance user and can therefore be accessed
without a code.
Service (A1) Parameters for qualified contractors: Code "1000"
Expert (A2) Parameters for service department.
f To access actual values and parameters which are reserved
for qualified contractors, enter the code "1000" for "View".
Press "OK".
"Service" is shown on the display, when this is entered correctly.
If you switch to the actual values or parameters, you see the en-
abled parameters.
Note
After entering the code, switch to the menu by pressing
the "MENU" button. If you first switch to the home screen,
the parameter block is reactivated.
 Fan control (depending on unit)
Use this parameter to switch fan control between "Constant flow
rate" and "Constant pressure".
Effect
Constant flow
rate
The appliance maintains a constant flow rate for both fans.
The unit works with the set values set for "Flow rate, stage
0" to "Flow rate, stage 3".
Constant pres-
sure
The appliance maintains a constant pressure at the extract
air fan. The unit regulates the pressure at the extract air
connection to the set values set for "Diff. pressure, stage 0"
to "Diff. pressure, stage 3". The flow rate that is established
there is used as the set value for flow rate control of the
supply air fan. "Supply air flow rate offset" is also included.
