How to vary parameters
Blocksystem o

control unit by the manufacturer (see the parameters table). These factory settings should not be varied
unless strictly necessary, and in all cases such operations are only to be carried out by qualified staff.
Parameters are not only divided by function, they are also divided according to their security/accessibility
levels:
Level 0 Setpoint parameters direct access (see paragraph 7.3)
Level 1 frequently used parameters access without password (see paragraph 7.5)
Level 2 configuration parameters access with password (see paragraph 7.7)
