BC10 basic controller<br />
Resetting the boiler or resetting faults<br />
If the boiler is down due to a fault, you can reset the boiler<br />
by pressing the "Reset" c button. This is only possible for<br />
so-called lock-out faults. There is another type of fault, socalled<br />
blocking faults, that reset themselves when the cause<br />
has been remedied.<br />
• Press the "Reset" c button to reset the boiler.<br />
The display shows "rE" while resetting.<br />
It is only possible to reset the boiler when a lock-out code<br />
(blinking fault code) is visible in the display.<br />
rE<br />
NOTICE<br />
If the burner returns to fault mode after resetting<br />
the boiler, you must resolve the fault using the<br />
servicing section in this document.<br />
Contact your supplier if necessary.<br />
9.1.3 Displaying the heating system status and/or<br />
faults<br />
The display of the BC10 basic controller shows the status of<br />
the heating system.<br />
In the event of a fault the display immediately shows the fault<br />
or the warning in the form of an error code (see<br />
subsection 13.2). The status display will flash if the fault is a<br />
lock-out fault.<br />
• Press the "Service" e button to switch between status<br />
displays or to read out the service and error codes.<br />
• Resolve the fault see subsection 13.3.<br />
The following status displays can be seen depending on the<br />
operating conditions:<br />
