Replacing the magnesium anode
For removing the magnesium anode,
see page 41.
!
Please note
A short circuit between magne-
sium anode and internal indirect
coil increases the protective
effect of the magnesium anode
and leads to corrosion damage
on the DHW cylinder.
Before inserting the electrical
cables, measure the resistance
between terminals
A
and
B
(see previous diagram). If the
resistance is significantly smaller
than infinite, check whether the
magnesium anode is touching
the internal indirect coil.
Commissioning assistant
The commissioning assistant guides you
automatically through all the menus
where settings have to be made.
!
Please note
Incorrect operation at "Coding
level 1" can result in damage to
the appliance and heating sys-
tem.
Always observe the installation
and service instructions; failure to
observe these will void your war-
ranty rights.

and function check can also be carried
out without the commissioning assis-
tant (see page 76, separate menu
