NOTE!
If no hygienic storage tank is being used, measures must be taken to kill legio-
nella 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 legionel-
la prevention at least once a week (168 hours). In the case of a large hot water
storage tank or a comparatively low consumption of hot water, legionella preven-
tion should be carried out regularly. A PT1000 temperature 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 wa-
ter with legionella is not completely ruled out.
Adapting the day This function ensures that the user-specified temperature is not undershot. If
curve there is not sufficient surplus power available, the external source will be started
up, if activated, or otherwise electricity will be drawn from the grid in order to en-
sure 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 pos-
sible for the surplus during the day due to the fact that a lower target tempera-
ture is selected.

NOTE!
Time ranges overlap.
If time ranges overlap, the higher temperature is used, so that, for example, a ba-
sic temperature 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.
