If the differential set here between cylinder 1 and cylinder 3 is exceeded and all conditions for switching on have
been met, the transfer pump is on.
If the differential between cylinder 1 and cylinder 3 falls below the value set here, the transfer pump is off.
If the differential between the measured temperature at the heat source (TS14) and the measured temperature at
the heat sink (TS15) is above the set value, the output signal is on (only with Temp differential controller (R)).
If the differential between the measured 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 (R)).
If the temperature at the heat source exceeds the value set here, the temperature differential controller switches off
(only with Temp differential controller (R)).
If the temperature at the heat source 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 (R)).
If the temperature at the heat sink exceeds the value set here, the temperature differential controller switches off
(only with Temp differential controller (R)).
Function description
• 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 an 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.
• One DHW system is installed and is controlled by an MM 100 module (coding switch set to 9).
• 2 DHW systems are installed. Each DHW system is controlled by an 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).
• 2 DHW systems are installed. One DHW system is controlled by the heat appliance. The 2nd DHW system is
controlled by an MM 100 module (coding switch set to 10).
• 2 DHW systems are installed. Each DHW system is controlled by an 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).
Switches thermal disinfection and daily heat-up of cylinder 1 on or off.
Switches thermal disinfection and daily heat-up of cylinder 2 on or off.
Switches thermal disinfection and daily heat-up of cylinder 3 on or off.
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 source (not possible with all user interfaces).
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 source (not possible with all
user interfaces).
Function description
The solar system only starts up once this function has been enabled.
Before starting up the solar thermal system, you must:
▶ Fill and vent the solar thermal system.
▶ Check the parameters for the solar thermal system and, if necessary, adjust them to suit the installed system.
This function can be used to switch off the solar system for maintenance purposes.
