8. Initial operation

Reinstallation

In case the appliance will be commis sioned again under different installation condi-
tions than during its initial ope ration, 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 para meters to works setting and lock the
heating.
It is now necessary to manually register the remote control (see operating instructions).
After the new registration, value "11" flashes in the display until the maximum power
rating has been selected. This condition will maintain when activating and deactivat-
ing the supply voltage.

Notes in case of remote control connection problems

In case of a failing connection between the remote control and the water heater, the
display indicates "no" and a cyclical flashing radio symbol. A keystroke restarts the
registration.
Under those circumstances reduce the distance to the water heater and check whether
the power supply is turned on.
After the batteries have been replaced and the selection of power rating, the display
of the remote control indicates the prior selected set value and the status of the appli-
ance.

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 setup menu parameter "Temperature
Limit" ("tL") must be set to a value less or equal 55 °C, in consultation with the cus-
tomer and the lock level must be activated.
When the device is operated with preheated water, it must be ensured that this tem-
perature is limited to 55 °C as well.

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
