Cool Top 7
6 Configuration menu
There are several options for the Cool Top. The installer supplies a
working system with the control element configured according
the installed options.
If the system changes or a new control element need to be in-
stalled then the configuration need to be changed.
ATTENTION
If you are unfamiliar with the system then do not
change settings. Only a Webasto service workshop
can use this menu.
Result: Change of settings could lead to system malfunc-
tion.
X Contact Webasto in case you have doubts about the
configuration settings.
