24. Parameter description
If a header sensor is connected to the appliance
(system configuration HG40 = 11 or 12) and an external DHW cylinder is in -
stalled, a hydraulic connection can be made between the DHW cylinder directly
to the heating appliance (before the buffer/header) or after the buffer/header.
Parameter HG61
DHW control unit
(DHW control)
Factory setting: see table
Individual setting:____
Boiler sensor:
Cylinder loading pump upstream of low loss header.
Control on boiler sensor; feed pump off during cylinder
heating.
Header sensor:
Cylinder feed pump downstream of low loss header.
Control on header sensor; feed pump on during cylinder
heating.

The excess temperature differential between the header temperature and the
boiler water temperature during header heating is selected with parameter
HG46. The boiler water temperature continues to be limited by the maximum
boiler water temperature (parameter HG22).
Parameter HG46
Excess boiler temperature, header
Factory setting: see table
Setting range: 0 to 20 °C
Individual setting: _____
Based on the maximum burner hysteresis HG 01, there is a linear reduction of
the burner shutdown point after the burner start. After expiry of the hysteresis
time (HG 33), the burner switches off when the minimum switching hysteresis
is reached (HG60).
Also see parameter HG01 diagram.
Parameter HG60
Minimum burner switching hysteresis
Factory setting: see table
Setting range: 2 to 30 °C
