3.9 Operating levels
The product has two operating levels:
– The operator level shows the most im-
portant information and offers set-up
options which do not require any special
prior knowledge.
– Specialised knowledge is required in or-
der to use the installer level (access for
competent persons). This is therefore
protected by an access code.
