“Fan mode” menu setting

Four menu items can be selected in the menu "Fan mode". The menu is preas-
signed with “automatic” as factory setting. This menu item appears when using
the control panel at decentralized devices or if "Temperature controlled" was
selected at central units for the fan-controlled variable.

Changing speed stages is described below as an example of the setting fixed
speed stages – the setting for 0 – 100% speed (rpm) works in the same way.
