may be legal requirements (
regulation on drinking water) for
thermal disinfection. Observe the instructions in the technical
documentation of the heat source.
•

Daily heat-up
Yes
The daily heat-up is only available for DHW heating with an MM 100/MM 200 module
or EMS 2 heat source. The entire DHW volume is automatically heated up daily at the
same time to the temperature that has been set via Daily heat-up temp. The heat-up is
not performed, if within 12 h before the set time, the DHW volume was already heated
up at least once to the set temperature (e.g. due to solar yield).
No
No daily heat-up.
