How to change settings
Actual settings are found in the first submenu, and they are not editable. Actual
settings consist of settings either of group 1 or 2, depending on which of these are
selected to be active. Settings of group 1 and 2 can be edited in the setting mode; see

groups 1 and 2 enables changing a whole group of settings at the same time. You can
switch between the setting groups 1 and 2 in three different ways:
1. by selecting “Group 1/Group 2” under the main menu group “Settings”
2. with a binary input signal BI
3. with the command V150 via serial communication bus.
