5.9 Viewing the parameters in the Installer level
b
Caution!
Inappropriate alterations can cause mate-
rial damage!
Incorrectly set parameters can cause material
damage to the heating installation.
Only competent persons may set the parame-
ters in the Installer level.
Never alter the settings in Menus C1 ... C11
and A1 ... A8 .
Menu 8 is the last menu in the Operator level.
The expert technician must enter a code number
(access code) in order to switch to the Installer level
and set the system-specific parameters.
The system-specific parameters are thus protected from
unintentional adjustment.
The operator can view the system-specific parameters
without entering a code number, but he cannot change
them.
This is how to view the system-specific parameters:
Requirement: Menu 8 Code level enable is displayed
( ¬ Chap. 5.1.1 ).

levels. You can still set all the parameters in
the Operator level.

ters in the Installer level again at any time.
