Cleaning And Maintenance - Rommelsbacher WP 250 Mode D'emploi

becomes visible. This shows that the automatic heating system has been triggered. If the heat level is
reduced within 10 seconds by means of the – sensor, the automatic heating system remains activated
for all settings. As long as the automatic heating system is on, the hot tray is operated with maximum
power during the initial heating period, which is in return dependent on the heat level selected. Once
the automatic heating peak is over, the luminous point will go out and the hot tray has reached the
desired temperature.
Safety functions
The Touch Control technology features several safety functions so as to prevent any unintentional activation.
• If you do not trigger any further functions within 10 seconds after the appliance has been switched
on, the hot tray will automatically switch off again.
• Beyond that, its electronics detects whether the sensors are touched purposefully. If you place a kit-
chen towel or similar on the appliance, it will not get triggered. The same goes for liquids that might
run over the glass surface.
• The safety switch-off will also get triggered if one or several sensors are activated for more than
12 seconds. In this case the control system switches off the hot tray. In the heat level display, an 'F'
flashes up. In this case, please switch off the appliance completely via the POWER sensor and start
the keep warm procedure anew.
• When the appliance is switched on, the sensors adjust themselves automatically to the environmen-
tal conditions. During that adjustment the glass surface above the sensors must not be covered. Only
if it is exposed to extreme external light, or if it is covered with a light object, an adjustment will not
be possible. This will also be indicated through an 'F' in the heat level display. In this case too, please
switch off the appliance completely via the POWER sensor, remove the external light and the cover
respectively and start the keep warm procedure anew.
