3-point heating curve
i
Function must be activated by qualified per-
sonnel.
Depending on the standard of building and insulation,
it is advisable to change over from the 2-point to a 3-
point heating curve. In contrast to the 2-point heating
curve, it is possible to stipulate a third temperature
11
, i.e. the heating curve can include a sharp deflec-
tion or bend.

7 DHW heating
DHW can be heated up in two ways:
–
With a
DHW tank
(the energy source of the DHW tank is the heating
boiler or a buffer tank
[1]
)
–
With a
fresh water module
(The energy source of the fresh water module is a
buffer tank
[1]
)
i
[1]
DHW area in the buffer tank
Warm water rises and collects in the upper-
most area ofthe buffer tank (= thermal stra-
tification). The DHW tank or the fresh water
module draws the required energy for DHW
heating from this uppermost area. Therefore,
this (held at an adjustable temperature level)
area in the buffer tank is also referred to as the
DHW area
.
