Replacing PCB and display

Danger!
d
Before replacing the component, observe the
safety information in Chapter 10.1.
e Danger!
Risk of fatal electric shock through contact
with live connections!
Disconnect the boiler from the power mains by
pulling out the mains plug or deenergising the
boiler using an isolating device with a contact
opening of at least 3 mm (e.g. fuses or power
switches). Only after this you may carry out
the installation.
• Comply with the assembly and installation manuals
provided with the spare parts.
Replacing the display or PCB
If you are replacing only one of the two components,
the parameter matching functions automatically. By
switching on the boiler, the new component takes over
the previously set parameters from the unreplaced
component.
Simultaneously replacing display and PCB
If both components are replaced at the same time (in
event of spare part installation) the boiler enters failure
mode when it is started up and displays the fault
message "F.70".
a Caution!
Risk of damage!
If you replace both components at the same
time, it is essential to check whether the cor-
rect spare part display for this boiler variant is
available. You must not use any other spare
part displays!
• Enter the number of the boiler variant under diagnosis
point "d.93" at the second diagnosis level in
accordance with Table 10.1 (see Chapter 9.1.2).
The PCB is now set to the boiler type and the
parameters of all adjustable diagnosis points
correspond to the factory settings. You can now make
the specific settings for the system.
