Please note
See section 7.9 on page 67 for the procedure for changing parameters (parameter
menu).
Legend parameter type and password
☺ = USER parameters (password = any).
I = INSTALLER parameters. Before changing the value, read the instructions carefully (password = 95)
C = BUILDER parameters. These parameters are typically set by the manufacturer, the default values may be
di󰀨erent from the recommended ones. Changing them may cause the connected equipment to malfunction.
These parameters are only visible by entering the correct password.
