(*) the third LED indicates whether or not the off-peak contact was correctly installed.
Third LED “on” if off-peak contact on.
Third LED “off” if off-peak contact out.
If the third LED is off during the off-peak period, the fault lies in the installation of the off-peak contacts.
When installing the device without off-peak contact, the third LED is always on.
Note
In an “error condition”, the device is out of order.
In the case of an “anode fault” or a “potentiometer fault”, the device can be manually activated for a heating cycle by press-
ing the “fast-heating” button . In this case the device heats until a water temperature of 40°C is reached. The device heats
at the installed power for single-power and boiler mode connections, for double-power connections it heats according to the
basic load of the connection, at 1kW, 2kW or 3kW.
If the fault could not be remedied, please contact the customer service operators.
Note
When the device is full with water and functions normally (there are no faults apparent), the device cannot be separated from
the mains voltage, otherwise the external power source anode stops functioning and the device rusts through. For complaints
of this nature, the warranty and guarantee do not apply.
After the assembly, please present the user with the instructions for use and explain the device to them.
