Overview: Configuration
This chapter describes what you have to do and know to configure
the system after it is installed.
NOTICE
The explanation about the configuration in this chapter
gives you ONLY basic explanations. For more detailed
explanation and background information, see the installer

expected. The configuration influences the following:

When you turn ON the user
interface for the first time (via the indoor unit), the configuration
wizard starts to help you configure the system.
