NOTE!
If no hygienic storage tank is being used, measures must be taken to kill legionella
bacteria.
If the boiler is operated at a temperature <60 °C for a relatively long period of time and no
hygienic storage tank is being used, measures must be taken to kill the legionella bacteria.
For private use, it is recommended to implement legionella prevention at least once a week
(168 hours). In the case of a large hot water storage tank or a comparatively low consump-
tion of hot water, legionella prevention should be carried out regularly. A PT1000 temper-
ature sensor is required for this function and can be sourced from Fronius under item
number 43,0001,1188.
Despite the setting of the "Legionella prevention" function, contamination of water with le-
gionella is not completely ruled out..
Adapting the day This function ensures that the user-specified temperature is not undershot. If there is not
curve sufficient surplus power available, the external source will be started up, if activated, or oth-
erwise electricity will be drawn from the grid in order to ensure a minimum temperature.
Up to four time periods can be defined so that, for example, higher hot water temperatures
are only certain to be available at night, but more potential is possible for the surplus during
the day due to the fact that a lower target temperature is selected.

NOTE!
Time ranges overlap.
If time ranges overlap, the higher temperature is used, so that, for example, a basic tem-
perature of 40 °C can be set for the whole day and is increased to 50 °C at certain times.
NOTE!
Undefined time ranges.
If time ranges are not defined, then in this time the system is not heated via the grid or the
external source, but only using PV surplus.
