DHW system settings can be adapted in this menu. For
example, maximum DHW temperatures, circulation pump logic
and thermal disinfection settings are made within this menu.
6 720 815 238-03.1O
WARNING: Risk of scalding!
The maximum DHW temperature ( Max. DHW
temp. ) can be set above 60 °C and during
thermal disinfection the DHW is heated to
above 60 °C.
▶ Inform all people concerned and make
sure that a mixer is installed.

description
DHW system I install.
(DHW system II
install.) No DHW system not installed
At the boiler Electrical assemblies and components for the selected DHW cylinder are directly
connected to the heat source (only available with DHW system I)
At the module Electrical assemblies and components for the selected DHW cylinder are connected to
the MS 100/MS 200 or MM 100 modules
Config. DHW at
boiler Hydraulic connections of DHW system I made to heat source (boiler).
No DHW No DHW system installed
3-way valve DHW system I is supplied via 3-way valve
Primary pump DHW system I is supplied via cylinder primary pump
Max. DHW temp. 60 ... 80 °C Maximum DHW temperature in the selected DHW cylinder
DHW e.g. 15 ... 60 °C
(80 °C)
Required DHW temperature for the DHW operating mode; the adjustment range
depends on the installed heat source.
DHW reduced e.g. 15 ... 45
... 60 °C (80 °C)
The required DHW temperature for DHW reduced operating mode is only available if a
DHW cylinder is installed. The adjustment range depends on the installed heat source.
Start temp.
differential e.g. – 20 ... – 5
... – 3 K
If the temperature in the DHW cylinder is lower than the required DHW temperature
and differs by the start temperature differential, the DHW cylinder is heated up. The
adjustment range depends on the installed heat source.
Switch-off temp.
diff. e.g. – 20 ... – 5
... – 3 K
If the DHW temperature at the lower temperature sensor of the stratification cylinder
is lower than the desired DHW temperature and differs by more than the switch-off
temperature differential, the DHW cylinder is not heated any further (only available if
MS 200 is used as cylinder primary module for stratification cylinder).
Flow temp. increase 0 ... 40 K Excess of the flow temperature required by the heat exchanger for heating up the
DHW cylinder. The default setting depends on the installed heat source.
DHW start delay 0 ... 50 s The start of the burner for DHW heating is delayed by the set duration, since water
preheated by the solar system is supplied to the heat exchanger (“solar heat”) and the
heat requirement can possibly be met without burner operation.
