The boiler is fitted with an advanced control unit. The heart of the
control is a microprocessor, the abc
controls the boiler.
Before calling in the installing engineer, first check if:
- the gas cock is open
- the maximum operating temperature setting is high enough
- the boiler control has been correctly set
- the main switch is on
- a sufficient water flow is possible (the radiator valves are entirely
opened)
- the water pressure is sufficient (> 0.8 bar).
Note down the failure message before resetting. Reset the failure
by pressing the reset-key on the instrument panel.
Control stop:
The control stop is a (temporary) boiler operating mode due to an
abnormal situation. The boiler switches to the neutral position so that
it can return to a normal state. The display then shows the shutdown
status (with code 9) again. The boiler control unit will, at first, try
several times to start the boiler again. The boiler shall operate again
when the causes of the control stop have been removed.
Fault:
If the shutdown condition still exists even after various automatic
control unit start attempts have been made or if a non-reproducible
phenomenon has arisen, the boiler switches to fault mode (also
known as lock-out). The boiler can only resume operation if the
cause of the fault is rectified and the 'RESET button' is pressed
The boiler display will show code 9.
The control stop codes can be read out as follows:
• Push the - key, and then the - key;
• The display shows     = 9;
• Push the [+]- key one time; the display shows 5u and the
control stop code.
• Note down the control stop code.

The boiler shall start automatically when the causes of the control
stop have been removed.
The list enumerates only control stop codes you might be able to
solve by yourself. If the control stop code continues to appear after
you seem to have rectified the fault, please contact your service
engineer. For control stop codes not mentioned in this list also
contact your service engineer.
