appliance from unwanted button operation. 

In cases where one or more buttons are 

pressed for longer than 12 seconds, the 

buzzer will sound for ten minutes to indicate 

an incorrect operation and the appliance 

will switch off. For example, an object may 

be placed on a button, or there could be a 

sensor failure and so on.

The safety switch-off will cause the hob to 

go into S-mode and all heater displays will 

flash “

F

”. If there is no incorrect operation 

present, both the visual and audible signals 

will disappear.

If residual heat is present, “

H

” will be 

displayed on all other heater displays.

Over Temperature Switch-Off

Due to the controls being very close to the 

heater in the middle of the front of the hob, 

it can occur that an incorrectly placed pot 

is not sensed by the sensor safety cut-off 

therefore heating up the hob to a very high 

temperature. This makes the glass and the 

buttons dangerous to touch.

To prevent the hob control unit from 

damage, the controls constantly monitor the 

temperature and the hob will automatically 

switch off if overheating occurs.

This will be indicated by the letter “

t

” in 

the heater displays until the temperature 

decreases.

Once the temperature has dropped, the 

“

t

” in the heater display will disappear and 

the hob control unit will revert back into 

S-Mode. This means that the user can 

reactivate the appliance by pressing   .

Operating Time Limitations

The hob control unit has a limitation on 

the operating time. If the heat setting for a 

heater has not been changed for a certain 

time, the heater will switch off automatically. 

A “

0

” will be displayed for 10 seconds, 

however there may be some residual heat 

present. The limit of the operating time 

depends on the selected heat setting. If a 

timer was associated with the heater, '00' 

will be shown on the Timer Display for 10 

seconds. After this, the Timer Display will 

switch off.

After a heater automatically switches off, as 

described above, the heater can be used 

and the maximum operating time for this 

heat setting is applied.

Residual Heat Functions

After all cooking processes, some heat 

will be stored in the vitroceramic glass 

called residual heat. The appliance can 

calculate roughly how hot this glass is. If 

the calculated temperature is higher than 

+ 60 ° C, then this will be indicated in the 

corresponding heater display for as long as 

the calculated temperature remains above 

+ 60 ° C, even after the appliance has been 

switched off.

The residual heat indicator has the lowest 

priority and is overwritten by every other 

display value, including during safety 

switch-off and the displaying of an error 

code. When voltage is supplied to the hob 

after a power interruption, the residual heat 

display indicator will flash. If a heater had a 

residual heat of greater than + 60 °C before 

the power interruption occurred, the display 

will flash while the residual heat remains 

or until the heater is selected for another 

cooking operation.

Hints and Tips

Important:

When ceramic heaters 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. 

This is normal at high temperatures, 

causing no damage to the hob and little 

delay in cooking times.

WARNING:

•  Never operate the hob without 

pans on the cooking zone.

•  Only use flat saucepans with a 

sufficiently thick base.

•  Make sure the bottom of the pan is dry 

before placing it on the hob.
