There are 16 fault codes stored in order of occurrence.
The fault code 'C0' is the current or last fault code and the
fault code 'CF' is that happened the longest time ago.
When no fault is stored at the displayed fault number, an
'FF' is displayed. It is also possible that 'EE' is displayed
for an internal error number. This means that the
controller is busy reading the memory. The lockout error
codes are listed in table 8.5.
The locking errors can be cleared by pressing the reset button S1.
(d) Block out fault code display
In this mode the block out fault codes can be displayed. The button S2 is used to select this mode and the
button S3 is used to cycle between the stored faults. Fault code reading is displayed by alternatively flashing
the fault number and the internal error number.

out error codes are listed in table 8.6.
The error will be reset when fault is cleared. To reset some internal errors switch power off, wait 10 seconds
and switch power on again.
8.1.3. Level - 3 Display Operations
The level 3 is used for setting the boiler
flow temperature and selecting the
boiler model. This level is intended for
use by the installer/service engineer.
The level 3 setting menu is accessed by
simultaneously pressing and holding the
push buttons S2 and S3 for at least 10
seconds.
The setting level is indicated by flashing
'0' on the on LH digit of the display and
solid '0' on the RH digit of the display.
(a)
Boiler model selection
The parameter to be set is selected by
using buttons S2 or S3. The display is
cycled using these buttons until 'B'
flashes on the LH digit and the current
boiler ID (1...5) is shown on RH digit.
The boiler models and their ID codes
are listed in table 8.4. To change the
boiler ID press and hold button S1 until
RH digit starts to flash. Select the boiler
ID using buttons S2 or S3. Press and
hold button S1 to confirm the selected
boiler ID.
If the selected boiler ID matches the ID resistor fitted, the RH digit will stop flashing. The controller will use
the boiler model specific data (e.g. fan speeds) for future control actions.
