Reinstallation

In case the appliance will be commis sioned again under different installation conditions
than during its initial ope ration, it may be necessary to adapt the maximum power rat-
ing.
A temporary short-circuit of the two pins on the right (see figure), e.g. with a screw-
driver acc. to EN 60900, will reset all heater parameters to works setting and lock the
heating. The display shows the menu to select the language. Choose your language,
after that the selection of power rating appears. This condition will maintain when acti-
vating and deactivating 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 "E1". A keystroke restarts the registration.
Under those circumstances reduce the distance to the water heater and check wheth-
er the power supply is turned on.

Shower application

The water heater's temperature must be limited to 55 °C, if it is connected to a show-
er. The temperature limit must be set to a value less or equal 55 °C in the setting menu,
in consultation with the customer and the lock level must be activated.
When the appliance is operated with preheated water, it must be ensured that this
temperature is limited to 55 °C as well.

Locking function

The operating mode of the appliance can be restricted.
Activation of the locking function
1. Select required parameters via the setting menu (see online user manual chapter
"Settings", subpoints "Temperature limit" and / or "Load shedding").
2. Disconnect the appliance from the power supply (e.g. by switching off the fuses).
3. Take the jumper off the power electronics and change to position "1" (see picture).
4. Put the appliance into operation again.
Deactivation of the locking function
1. Disconnect the appliance from the power supply (e.g. by switching off the fuses).
2. Take the jumper off the power electronics and change to position "OFF" (see pic-
ture).
3. Put the appliance into operation again.
