Operating time in seconds
The temperature of the cooking zones is time-adjusted, in the same way as the energy control
unit. Depending on the cooking setting, the corresponding cooking zone will be switched on or
off as described in the following table.
This means, for instance, that at cooking setting 6 the control unit is switched on for 14 seconds
and is then switched off for 33 seconds. Thus the total amount of time is 47 seconds. Then the
process starts again.

The automatic boost function
All cooking zones are equipped with an automatic boost function.
Maximum power is used for the boost. The time period of the
boost depends on the selected cooking setting. After the time
has elapsed the cooking zone automatically switches back to the
selected cooking setting.
When you select the respective cooking setting by touching the
minus pad, the boost function will switch on automatically.
During automatic operation an "A" lights up in the display
alternately with the selected cooking setting.
When you select the required cooking setting by pressing the
plus pad, it is necessary to press the plus pad again after reaching
cooking setting 9 if the automatic boost function is to be activated.
Then select the required cooking setting.
"A" lights up in the display alternately with the selected cooking
setting until the boost has finished.
Time in seconds
The automatic boost works at full power and for the time specified in the table (depending on the
cooking setting):
Cooking setting 1 2 3 4 5 6 7 8 9
Seconds 80 165 246 326 411 80 165 135 10
Minutes 1,3 2,7 4,1 5,4 6,8 1,3 2,7 2,2 0,0
After this time, the automatic boost switches off and cooking continues as specified in the table.
At setting 9 the cooking zone functions at full power, thus obviating the need for the boost function.

Residual heat indicators
The lock is indicated by 3 flashing control indicators.
Be careful: Switching off the hob does not deactivate the lock!
Operating the sensor lock prevents unauthorised
persons from using the appliance. In order to activate
this lock the hob has to be in operation.
Activating the lock:
Press the sensor lock for 2 seconds. You may also
switch on the lock while cooking. Then, however, you
can only reduce the heat or switch off the hob.
Deactivating the lock:
after 3 secs. max.
Simultaneously touch the pads under the two flashing control indicators on the left. After not
more than 3 seconds touch the pad for the sensor lock.
Note: When the power supply has been interrupted the childproof lock is no longer active.
As long as the cooking zone is still hot, an "H" will appear in
the display when the cooking zone has been switched off.

Disassembling the electric hob
Slide the lifter as far as it
will go under the back or
the sides of the hob (never
under the front).
Remove the hob and put
it onto the worktop. Do
not forget to put an
intermediate layer
between the hob and the
worktop to prevent the
worktop from being
scratched.
Press the lifter onto the
worktop, the hob is lifted
off the clips.

To exchange the Touch
Control unit, you must
remove the glass ceramic
top. To do this unscrew the
screws on both sides of the
hob.
(In case of EKE 854.1 three
screws have to be loosened
at the front.)
Then the glass ceramic top
can be removed by lifting it
upwards.
Changing the Touch Control unit
Electronic components and electronic modules are always sensitive to high voltage. The Touch
Control unit is equipped with C-MOS-components which are very sensitive to electrostatic charging.
Equipotential bonding should be performed by simultaneously taking hold
of the conductive protection bag of the Touch Control unit and the metal
case of the hob. Do not move with it afterwards.
For this reason the Touch Control unit should be ready at hand!

Installing the Touch Control unit
Before the Touch Control
unit is installed, align the
metal brackets. Make
sure that all the springs
are on the metal parts.
Install washers in addition
to the front springs.
Be certain that the cables
are led around the metal
parts provided for them,
as shown in the diagram,
and press them onto the
base of the hob.
If assembly makes it
necessary to loosen some
of the cable binders, it is
essential that these are
replaced.
It is also important to
make sure that the
insulation material is put
back into the correct
positions.

Returning the Touch Control unit
Electronic components must always be treated with care and specially protected during transport.
Furthermore, we request you to be very careful when disassembling the components as they
are recycled to save costs.
For this reason the following packing instructions must be observed:
Each electronic component must be packed separately in a cardboard box lined
with nap foam.
When returning electronic components, use only the original packaging in which
they have been supplied. This packing material can also be obtained via our
Spare Parts Department.
Even if they have been properly packed, electronic components must not be
thrown around.
Packing:
1. Put the unit into an antistatic flat bag, roll up the bag up and close it.
2. Put the unit with the bag onto the nap foam of the box in such a way that the
printed circuit boards are in a vertical position.
3. Assemble the cardboard box, close it and seal with scotch tape.
4. It is very important that the box is marked with the green "R" sticker.

Electrical connection
Aligning the glass ceramic hob
By skilfully tightening the
screws (one screw, then
the screw on the opposite
side and so on) you can
slightly adjust the position
of the marked cooking
zones on the glass
ceramic top in relation to
the heating spirals.
In the example illustrated
the glass ceramic top
would shift in the direction
of the arrow if the screws
are tightened in the
specified sequence.
· The built-in hob must be connected to the mains supply by a qualified electrician who is
authorized to carry out such work.
· Both legal wiring regulations and the requirements of your local electricity supply board
must be fully complied with.
· When connecting the hob, a device must be provided which enables all-pole disconnection
of the hob from the supply with a gap construction of at least 3 mm. Circuit breakers, fuses
and contactors are considered to be suitable disconnecting units.
· When connecting and repairing the appliance disconnect it from the electricity supply with
one of these devices.
· Overall protection against electric shock must be ensured by the installation.
· The earthed conductor lead must be sufficiently long so that, in the event of failure of the
strain relief, it is not subjected to strain until after the live wires of the connection cable.
· Any superfluous cable must be removed from the installation area beneath the appliance.
