Multiple Power System:
The rated capacity (max. power
consumption) is 11 kW / 400 V
and can be changed internally to
13.5 kW.
MADE IN GERMANY
Before making the electrical connection, fill the
mains and the appliance with water by carefully
opening and closing the hot water tap in order to
vent completely. After every draining (e.g. after work
on the plumbing system or following repairs to the
appliance), the heater must be re-vented in this way
before starting it up again.
If the water heater cannot be put into operation, the
temperature cut-out or the pressure cut-out may have
tripped during transport. If necessary, reset the cut-out.
Selection of power rating
Only by authorised specialist, otherwise lapse of
guarantee!
Upon first connection of the appliance to the supply
voltage, select the maximum power rating. Only after
having set the power rating, the heater provides its
standard operation mode.
The maximum allowable power rating at installation
site depends on the local situation. It is imperative
to observe all data shown in the table “Technical
specifications”, in particular the required cable size
and fuse protection for the electrical connection.
Moreover, the electrical installation must comply with
the statutory regulations of the respective country
and those of the local electricity supply company
(Germany: DIN VDE 0100).
1. Switch on the power supply to the appliance. The
digital display on the appliance must light up.
2. When switching on the supply voltage for the
first time, the value “11“ flashes in the display.
If not, please carefully read the below note
“Reinstallation”.
3. Select the maximum allowable power rating
depending on the local situation via the up and
down arrow keys: 11 or 13 kW.
4. Press key to confirm the setting. The appliance
starts operating.
5. Mark the set power rating on the rating plate.
6. Open the hot water tap. Check the function of the
appliance.
7. After having set the maximum allowable power
rating, the heating element will be activated after
approx. 10 seconds of water flow.
8. Explain the user how the instantaneous water
heater works and hand over the operating
instructions.
9. Fill in the guarantee registration card and send it to
the Customer Service or use the online registration.
Remote control
The water heater’s temperature must be limited to 55
°C, if it is connected to a shower and controlled with
a remote control system. The service menu parameter
“Temperature Limit “(“tL”) must be set to a value less
or equal 55 °C, in consultation with the customer and
the lock level must be activated.
When the device is operated with preheated water, it
must be ensured that this temperature is limited to
55 °C as well.
Reinstallation
In case the appliance will be commissioned again
under different installation conditions than during
its initial operation, it may be necessary to adapt the
maximum power rating. A temporary short-circuit of
the two pins, e.g. with a screwdriver acc. to EN 60900
(see figure), will reset all heater parameters to works
setting and lock the heating.
Value “11“ flashes in the display until the maximum
power rating has been selected. This condition will
maintain when activating and deactivating the supply
voltage.
Lock Level
The operating mode of the appliance can be
restricted. The service menu can be used to configure
the appliance.
Activation of the lock level
1. Set required lock level in the service menu (refer
to chapter “Service menu” in this installing
instructions).
2. Disconnect the appliance from the power supply
(e.g. by switching off the fuses).
3. Move the jumper on the power electronics from pin
2 to pin 1 (see figure).
4. Put the appliance into operation again.
Deactivation of the lock level
1. Disconnect the appliance from the power supply
(e.g. by switching off the fuses).
2. Move jumper from pin 1 to pin 2.
3. Put the appliance into operation again.
