Overheating protection 230 V
The 230 V heating facility has a mechanical
overheating switch. If the 12 V power supply
is interrupted during operation or during the
after-run period, for example, the temperatures
within the unit could activate the overheating
protection.
To reset the overheating protection, allow
heater to cool, remove connection cover and
press red reset button.
