Once the temperature decreases ‘t’ will no longer be displayed and the hob control
unit reverts back into

Operating Time Limitations
The hob control unit has a limitation on the operating time. If the heat setting for a zone
has not been changed for a certain
length of
time, the
zone
will turn off automatically for
10 sec onds, a ´ 0 ` is displayed. Some residual heat may be present. The limit of the
operating time depends on the selected heat setting.
After a zone has been automatically turned off, as described above, it can be used a t
the maximum operating time for th
e
heat setting
that
is applied.
Residual Heat Functions
After all cooking processes there is some heat stored in the vitroceramic glass called
residual heat. The appliance can calculate roughly how hot the glass is. If the
calculated temperature is higher than + 60 ° C, then this will be indicated in the
corresponding zone setting display. After the zone or the hob control has been turned
off, the residual heat display is shown as long as the calculated zone temperature is >
+ 60°C.
The residual heat indicator has the lowest priority and is overwritten by every other
display value and during " safety switch offs " and the displaying of error codes. When
voltage is supplied to the hob after a power interruption, the residual heat display
indicator flashes. If a zone ha s a residual heat of greater + 60°C before the power
interruption occurred, the display will flash while the residual heat remains or until the
zone is selected for another cooking operation.
Hints and Tips
Important: When ceramic zones are operated in higher heat settings, the heated
areas may be seen switching on and off. This is due to a safety device, which
prevents the glass from overheating. Some switching on and off when cooking at high
temperatures is quite normal, causes no damage to the hob and little delay in cooking
times.
