reaches 6 kelvin below the set nominal value.
• The pump is switched off when the measured value
reaches 2 kelvin below the set nominal value.

7.4.2.3 Extension of the maximum adjustable
temperature
The maximum possible output temperature in the con-
troller is preset to 60 °C at the factory. If your applica-
tion requires higher temperatures, you have the option
to increase the maximum temperature to up to 75 °C.
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.
NOTICE
High fl uid temperatures (> 60 °C) increase
the risk of corrosion and energy costs
f
Do not set the hot water temperature any
higher than absolutely necessary.

7.5 Handover to the user
f
Once commissioning is complete, complete the
handover report as soon as possible. The relevant
form can be found in the appendix. Sign the report
and provide the user with a copy.
f
Hand these operating instructions and all other
relevant documents (e.g. accessory manuals) over
to the user. These operating instructions must be
available at the installation location.
