Malfunctions <strong>and</strong> Errors<br />
7.2.2 Locking Codes<br />
The boiler controller also recognises errors that may lead to the heating dem<strong>and</strong><br />
lockup, but does not recognise errors that may lead to a shutdown. If the error is resolved,<br />
it disappears, but will be recorded in the error log. The descriptions of these<br />
codes are as following:<br />

This error is caused by the electrical supply<br />
being too low (less than 185 V alternating<br />
current).<br />
The power frequency shows a deviation of<br />
more than +/- 5 %.<br />
- 37 -<br />
Check the electrical current. If the electrical supply<br />
returns to normal, the error will disappear<br />
within 10 sec.<br />
Check the power frequency. If the power frequency<br />
returns to normal, the error will disappear.<br />
