9 Service and Operation
The hot water temperature may be set between * and 85 °C using
the dial. We recommend the setting of 60 °C. Heat wastage and
calcification are lowest here.
As hot water is extracted the amount of hot water available in
the reservoir decreases. The less hot water available, the fewer LEDs
are lit up.
The heating period is dependent upon the volume of water in the reservoir,
the cold water intake temperature, and the set heat output.
See technical data table (page 12)
The hot water storage unit may be used optionally for
closed (pressurised) operation
suitable for service of multiple tapping points
open (de-pressurised) operation
suitable for service of one tapping point
There are three variations of electrical connections to choose from:
Single-power operation
Reheating occurs automatically subject to the power supply.
The button “fast-heating”
is only used for the reset
and diagnostic routine functions (technician).
Double-power operation
During off-peak periods, the hot water storage unit
automatically heats the contents of the reservoir
at
the configured basic performance. The quick heating may be
activated by pressing the fast-heating button
.
As the device is heating up the LED lights up, before going
out again as soon as the set temperature is reached. The “fast-
heating” switches itself off automatically.
Boiler mode operation
In this mode the hot water storage unit heats the contents of
the reservoir once upon the initial operation at the connected
and configured basic performance. Each further heating proce-
dure must be started manually by pressing the button fast-
heating .
10 LED display anode and service
In normal operations, the LED “anode” is constantly lit,
the LED “service” is off.
If these conditions are not respected an “error condition” occurs.
To begin with, please reset the device RESET. To do this, proceed
as follows:
Firstly turn the dial
to the setting “●”.
After that, press the “fast-heating” button .
If the cause of the error condition does not exist directly after the reset,
the device will again return to its normal mode of function. Otherwise
the device will again indicate an “error condition”.
In this case please contact the customer service operator.
11 Cleaning
• Wipe with a damp cloth. Do not use any sharp or coarse cleaning
products.
• Do not use a steam cleaner.
12 Customer Service
In order to avoid hazards, repairs may only be carried out by
a customer service operator licensed by us.
The initial service through our customer service operator should take place
around two years after the first operation. At this time, the device will
potentially be decalcified. Afterwards, the customer service operator will
recommended a date for the next service. Specify the E-No. and FD-No.
when phoning the customer service operator!
When requesting customer service, please enter the E-No. and
the FD-No. of your device.
You will find the numbers on identification plate between the water
access pipes of the reservoir.
