Operating Time Limitation
The cooktop control has a limitation on the operating time. If the heat setting for a hotplate has not been
changed for a certain time, then the hotplate will turn off automatically (a “0“ is displayed for 10 seconds, then
the residual heat sign “H” is displayed). The limit of the operating time depends on the selected heat setting.
Heat settings 1-2: 6 hours.
Heat settings 3-4: 5 hours.
Heat setting 5: 4 hours.
Heat settings 6-9: 1.5 hours.
After an automatic turn off of a hotplate (as described above) the hotplate is operable again and the maximum
operating time for this heat setting is re-applied.
Residual Heat Functions
After all cooking processes there is some heat stored in the vitroceramic glass called residual heat. The
control can calculate roughly how hot the glass is in the worst case. If the calculated temperature is higher
than + 60 ° C, then this will be indicated in the corresponding Heat Level Display after the hotplate control has
turned off with a red “H”. The residual heat display is shown as long as the calculated heater temperature is >
+ 60 ° C.
The display of the residual heat has the lowest priority and is overwritten by every other display value, during
safety turn offs and the display of an error code.
When the supply voltage is re-applied to the cooktop after an interruption to the supply voltage, the residual
heat display flashes if the corresponding hotplate had a residual heat of g 60 ° C before the power
interruption occurred. The display will flash until the maximum residual heat time has expired or the hotplate
has been selected and activated.
