3 Function description
3.1 Sensor operation with the control panel
Since the number and location of the honeycomb units can be individually determined, the control
units must be adapted to the arrangement of the honeycomb unit configuration which you have se-
lected. You may use your creativity here. The markings on the control unit correspond to the arran-
gement of the honeycomb units on the hob, so as to make operation as intuitive as possible.
A control unit can operate up to 6 honeycomb units. Should more than 6 honeycomb units be con-
nected in a system, a second control unit is required. The control function of the controller always
includes also control of the dual-circuit cooking zone and auto cook, as well as the child safety fea-
ture which locks out the electronics.
AKey-sensor and
BLock sensor for the childproof lock
CControl panels for the honeycomb units with
Plus and Minus sensors (example configu-
ration)
DCentral OFF sensor
EThis panel has no switching function.
It simply indicates the position of the
control unit.

3.2 Turn on
Hold down the central OFF sensor for ca. 2 seconds.
A vertical bar between the central OFF sensor and the
childproof lock illuminates.
The appliance is ready (stand-by mode).
3.3 Turn off
Briefly (ca. 0.3 seconds) press the central OFF sensor.
The control unit automatically switches itself off again if:
- no other sensor is pressed within 20 seconds*,
- the control unit remains unused after 10 minutes of
operation, or
- a cooking zone sensor is pressed for longer than 20
seconds*.
* After 10 seconds an acoustic warning signal indicates
that the unit will shut itself off after 10 more seconds
have elapsed.
3.4 The cooking levels
There are 9 cooking levels (1-9). The cooking levels are
indicated in the display for the respective cooking zone.
The desired level can be selected using the Plus sensor
(cooking without auto parboil) or the Minus sensor (coo-
king with auto parboil). There is no null position.
All cooking zones have an auto parboil function availa-
ble.
3.5 Cooking without auto parboil
Press the Plus sensor. The cooking zone starts at Level
5. Now select the desired cooking level.

3.6 Cooking with auto parboil
Press the Minus sensor. The cooking zone starts at Le-
vel 9, and the auto parboil function is activated. Now
switch down to the desired cooking level. After the auto
parboil function is completed, the cooking zone switches
over to the desired cooking level.
During auto mode, the display flashes ”A” alternating
with the preset cooking level.
One can still switch back and forth between the indivi-
dual cooking levels; the remaining time for the auto par-
boil is carried over.
3.7 Switch off the cooking levels
Press the Plus and Minus sensors simultaneously for
ca. 3.5 seconds.
Hold the Minus sensor down. The cooking levels are
counted down. After cooking level 1 the cooking zone
goes off.
3.8 Dual-circuit cooking zones EKW 306.1
Dual-circuit zones are indicated by a blinking dot in the
associated display.
Hold down the Plus and Minus sensor simultaneously
for ca. 1 second. The indicator light next to the display
for the cooking level comes on and an acoustic signal is
generated.
3.9 Switch off the dual-circuit zone
Hold down the Plus and Minus sensor simultaneously
for ca. 1 second.
The indicator light goes out and an acoustic signal is
generated to indicate that the dual-circuit zone is off.

3.10 The central OFF function
The central OFF sensor can be used to immediately
turn off all functions independent of each other.
3.11 Child safety feature
(sensor lockout)
The sensor lockout can be used to prevent unauthorized
use of the device. Disable the hob as follows:
Press the key sensor until an acoustic signal is heard.
Then press the lock sensor until an acoustic signal is
heard.
Lockout status is indicated by 3 horizontal bars in the
stand-by display.
To unlock the cooking hob:
Press the key sensor until an acoustic signal is heard.

7For internal use only
Then press the lock sensor until an acoustic signal is
heard.
Unlock status is indicated by a vertical bar in the stand-
by display. Sensor lockout remains in effect even after
the system is turned off. It is also unaffected by presen-
ce or absence of mains power.
3.12 Additional functions
Pressing two or more sensors at the same time, e.g. if a
pot is accidentally placed against the sensors, does not
generate a switching function. After 10 seconds an audi-
ble signal is heard, and after 20 seconds the entire elec-
tronics is shut off. Exceptions:
- Disabling the sensor lockout
- Switching dual-circuit zone on or off
- Switching off cooking zones.
If a sensor is actuated after reaching the highest level, a
signal is heard after 10 seconds, and after 20 seconds
the entire electronics is shut off.
There is no automatic start-up after a power loss.
4 Electrical connection
4.1 Connecting honeycomb element to
control unit
A control unit can handle up to 6 honeycomb elements.
Up to 3 EKW 306.1 dual-circuit cooking zones can be
connected to one control unit.

Follow the wiring diagram exactly when making
connections!
A wiring diagram is included with the ESW 307.6 control
unit, with a number corresponding to each honeycomb
element. These numbers are also found on the wiring
guide for the honeycomb element. This allows you to
easily determine which sensors control which honey-
comb elements.
4.2 The connector
for the EKW 306.1 cooking zone has 3 connections
for the EKW 306.1 dual-circuit cooking zone has 4
connections
The connections are marked on the plugs
(N / L1 / L2 / etc.)
4.3 Connecting the mains
This connection must be made by trained personnel.
Standard good electrical practice as well as any regula-
tions of the local electricity provider must be strictly ob-
served.
The control must have no voltage to it during assembly.
Open the isolation device on the installation side.
Insert the compact plug for the control into its mate on
the connection side.
Connected load: 400 V 3N~ 50 Hz
Power consumption: max 8.7 kW
Using single-phase mains supply is only possible if ma-
ximum two single- and one dual-circuit elements are
connected.
