Illust. 33: Displays and operating elements
(1) Nominal hot water temperature and status
display
(2)
Button (+) for increasing the set value
(3) Control LED
(4) Button (-) for decreasing the set value
- The hot water temperature can be adjusted
between 25 °C and 75 °C.
- The default hot water temperature is 60 °C.
f
Press the “+” or “-” button to increase or reduce the
hot water temperature accordingly.
 The displayed temperature is saved after 5 seconds
of inactivity.
CAUTION
Risk of scalding due to excessively hot po-
table water at the draw-off points!
A controller setting or defect may cause the hot
water temperature at the draw-off points to rise
to roughly the same temperature as the storage
cylinder water.
f
According to DIN EN 806 and DIN 1988, all
draw-off points must be provided with pro-
tection against scalding if there is a risk of
scalding due to high heating water tempera-
tures in the buffer storage cylinder.
f If you do not apply scalding protection to
all draw-off points, reduce the temperature
of the storage cylinder circuit so far that the
temperature in the storage cylinder – and
therefore the potable water temperature –
cannot pose any risk of scalding.
f
Instruct the user of the system to ensure the
storage cylinder temperature remains low all
year round.
- Sustained pressing of the “+” or “-” button
causes a continuous increase or decrease in
the numbers on the display.
- If the power supply fails during confi guration,
the previous value remains stored.
- The display turns off after 30 seconds of in-
activity. Press a button to display the current
set value.
8.2 Emergency operation (manual
operation)
Emergency operation ensures hot water can be pre-
pared even in the event of a sensor failure.
Emergency operation means that the speed of the
primary pump is fi xed at 50 % of the power. The LED
fl ashes green/red when emergency operation is active.
