6.4 Menu structure

“Program” menu is composed of totally four folders

1) Parameters"#"change unit parameters

2) Functions"#"manual operations (switch ON / switch OFF, alarm

quit, historic alarm delete, multi function key use)

3) Password"#"define visibility levels for parameters/folders

4) Alarm log"#"display alarm log

Parameter folder gives access to following sub-folders
