Example of a flow meter
Set the required total air flow to the maximum
flow rate. (MENU>Login>VENTILATION
SETTINGS>HIGH SETTING)
= Air flow almost at limit value
= Air flow insufficient
If the limit value is lower than the desired air flow,
a further system test must be carried out.
(MENU>Login>SYSTEM TEST) For more
information, see chapter 6.14.
Press
to switch the commissioning mode off
again directly without saving the value entered.
Press
to save the value entered.
REPEAT THESE STEPS FOR THE MEDIUM AND
LOW SETTINGS
Measure the air flow at each opened valve using
a flow meter.
Write down the air flow for these valves.
Adjust the opened valves to the required air flow

Complete an installation/test report. An example
can be found in the back of the user manual.
The unit’s installation height must be specified in
the “ALTITUDE” menu.
(MENU>Login>ALTITUDE>)
In the menu BALANCE SETTING an unbalance
between supply and exhaust air can be set.
(MENU>Login>BALANCE SETTING>BALANCE
FINE TUNE)
BALANCE SETTING selection: ‘+’= more exhaust
air; ‘-’= less exhaust air.
With the FIREPLACE MODE setting activated,
only less exhaust air (=’-’) is possible.
FROST PROTECTION selection (without
preheater):
(BALANCE SETTING>FIREPLACE MODE)
■
FIREPLACE MODE active? YES: (Default)
Exhaust and supply air remain in balance at all
times. As a result, the unit switches off faster
in frost mode than in inactive fireplace mode.
■
FIREPLACE MODE active? NO: There is more
supply air than exhaust air. So in frost mode,
ventilation is maintained longer.
Malfunctions of the preheater or bypass can only be reset after the system test has been carried out again.
