In case of fault
(*) 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 pressing 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.
