11.2.4 Heating partial load
The heating partial load of the Vaillant ecoTEC plus boiler is
factory set to "auto". This means that the boiler independ-
ently determines the optimum heating output depending on
the current heat demand of the system. A setting is nor-
mally no longer required. The setting can also be changed
at a later point using diagnostics code D.000.
11.2.5 Auxiliary relay and multi-functional module
Additional components that are attached to the boiler can
be adjusted directly here.
This setting can be changed using diagnostics codes D.026,
D.027 and D.028.
11.2.6 Competent person telephone number
You can store your telephone number in the unit menu.
The operator can display this number in the information
menu. The telephone numbers can be up to 16 digits long
and must not contain any spaces. If the telephone number
is shorter, end the entry after the last digit by pressing the
right-hand selection button.
All of the digits to the right will be deleted.
