Solar infl. heat. circ. Off: Solar influence switched off.
1 ... 4
– 1 ... – 5 K: Influence of solar on the set room
temperature: at a high value, the flow temperature of the
heating curve is reduced at a correspondingly greater rate
in order to enable greater passive solar energy input
through the building's windows. At the same time this
reduces a temperature overshoot in the building and
increases the comfort level.
• Increase heating circuit solar influence ( – 5 K = max.
influence) if the heating circuit heats rooms that have
large south-facing windows.
• Do not increase heating circuit solar influence if the
heating circuit heats rooms that have small areas of
north-facing windows.
Reset solar yield Yes: Resets the solar yield to zero.
No: No change
Reset solar Yes: Resets the solar optimisation calibration and restarts
optimisation it. The settings for Solar yield/optimisation remain
unchanged.
No: No change
Set temp. Match-F. Off: Regulates to a constant temperature differential
between collector and cylinder (match-flow).
35 ... 45 ... 60 °C: Match-Flow (only in combination with
speed modulation) is used to quickly heat the top part of
the cylinder to 45 °C, for example, in order to prevent the
potable water being reheated by the heat producer.
Glycol content 0 ... 45 ... 50 %In order to obtain accurate function from
the heat meter, the glycol content of the solar fluid must be
specified (only with Heat meter (L)).

Transfer
Menu item Adjustment range: Function description
Transfer switch-on 6 ... 10 ... 20 K: If the differential set here between
diff. cylinder 1 and cylinder 3 is exceeded, and all conditions
for switching on have been met, the transfer pump
between the cylinders is on.
Transfer switch-off 3 ... 5 ... 17 K: If the differential between cylinder 1 and
diff. cylinder 3 falls below the value set here, the transfer pump
between the cylinders is off.
Switch-on diff. diff. 6 ... 20 K: If the differential between the measured
ctrllr temperature at the heat source (TS14) and the measured
temperature at the heat sink (TS15) is below the set value,
the output signal is off (only with Temp. differential
controller (M)).
Switch-off diff. diff. 3 ... 17 K: If the differential between the measured
ctrllr temperature at the heat source (TS14) and the measured
temperature at the heat sink (TS15) is below the set value,
the output signal is off (only with Temp. differential
controller (M)).
Max source t. diff 13 ... 90 ... 120 °C: If the temperature at the heat source
ctrllr exceeds the value set here, the temperature differential
controller switches off (only with Temp. differential
controller (M)).
Min. src. temp. diff 10 ... 20 ... 117 °C: If the temperature at the heat source
cont. exceeds the value set here and all conditions for switching
on have been met, the temperature differential controller
switches on (only with Temp. differential controller (M)).
20 ... 60 ... 90 °C: If the temperature at the heat sink

Solar DHW
WARNING:
Risk of scalding!
▶ If DHW temperatures above 60 °C are set or thermal disinfection is
switched on, a mixer must be installed.

DHW controller act. Boiler
• One DHW system is installed and is controlled by the
heat appliance.
• 2 DHW systems are installed. One DHW system is
controlled by the heat appliance. The 2nd DHW
system is controlled by a MM 100 module
(coding switch set to 10).
Thermal disinfection, reheating and solar optimisation
only have an effect on the DHW system that is controlled
by the heat appliance.
External module 1
• One DHW system is installed and is controlled by an
MM 100 module (coding switch set to 9).
• 2 DHW systems are installed. Both DHW systems are
controlled by a MM 100 module
(coding switch set to 9/10).
Thermal disinfection, reheating and solar optimisation
only have an effect on the DHW system that is controlled
by external module 1 (coding switch set to 9).
External module 2
• 2 DHW systems are installed. One DHW system is
controlled by the heat appliance. The 2nd DHW
system is controlled by a MM 100 module (coding
switch set to 10).
• 2 DHW systems are installed. Both DHW systems are
controlled by a MM 100 module
(coding switch set to 9/10).
Thermal disinfection, reheating and solar optimisation
only have an effect on the DHW system that is controlled
by external module 2 (coding switch set to 10).
Therm.dis./daily Yes: Switch on thermal disinfection and daily heat-up of
ht cyl1 1st cylinder.
No: Switch thermal disinfection and daily heat-up of
cylinder 1 off.
Therm.dis./daily Yes: Switch on thermal disinfection and daily heat-up of
ht cyl2 2nd cylinder.
NoSwitch thermal disinfection and daily heat-up of
cylinder 2 off.
Therm.dis./daily ht Yes: Switch off thermal disinfection and daily heat-up of
cyl3 3rd cylinder.
No: Switch thermal disinfection and daily heat-up of
cylinder 3 off.
Daily heat-up time 00:00 ... 02:00 ... 23:45 h: Start time for daily heat-up.
Daily heat-up ends after a maximum of 3 hours. Only
available if the MS 200 module is installed in a BUS system
without a heat producer (not possible with all user
interfaces)
Daily heat-up temp. 60 ... 80 °C: The daily heat-up ends once the set
temperature is reached, or, if the temperature is not
reached, after a maximum of 3 hours. Only available if the
MS 200 module is installed in a BUS system without a heat
producer (not possible with all user interfaces)
