Overview: Configuration
This chapter describes what you have to do and know to configure
the system after it is installed.
Why
If you do NOT configure the system correctly, it might NOT work as
expected. The configuration influences the following:
▪ The calculations of the software
▪ What you can see on and do with the user interface
How
You can configure the system via the user interface.
▪ First time – Quick wizard. When you turn ON the user interface
for the first time (via the indoor unit), a quick wizard starts to help
you configure the system.
▪ Afterwards. If necessary, you can make changes to the
configuration afterwards.
INFORMATION
When the installer settings are changed, the user interface
will request to confirm. When confirmed, the screen will
shortly turn OFF and "busy" will be displayed for several
seconds.
