Buffer Tank Charging - SOLARFOCUS ecotopzero Manual

Activate the weather influence hot water function only
if the DHW tank/hot water area is heated by a solar
power system, or is charged from a buffer tank that is
heated by a solar power system.
Good weather forecast delays the start of the burner
in the event of a request from the DHW tank/hot water
area.(fehlender oder ungültiger Codeausschnitt)
In this way, the thermal solar system has the means
and time to charge the tank at a later stage without
the boiler having to start.
The maximum possible delay is calculated by an
algorithm and depends inter alia on the following:
– Weather forecast
– Date and time
– Deviation between actual/required buffer tank tem-
perature
– Duration of buffer tank temperature deviation
– Individual setting influence on weather prognosis
The bar can be used to set the duration of the delay
for each DHW tank/hot water area individually.
0% = no delay to burner start..
100% = maximum delay of burner start in the event of
good weather being forecast.
If the function delays burner start due to good
weather being forecast, then the weatherman icon
appears in the main hot water menu.
The green column indicates the delay. When 100% is
reached, the burner starts and the DHW tank is
charged.

15.4 Buffer tank charging

This menu 1 is only visible when a buffer tank is
enabled in the boiler control.
In the event of good weather being forecast, the buf-
fer tank is charged for a shorter time within the
release time.
In this way, the thermal solar system has the means
and time to charge the tank at a later stage without
the boiler having to start.
The maximum possible delay is calculated by an
algorithm and depends inter alia on the following:
– Weather forecast:
– Date and time
– Deviation between actual/required buffer tank tem-
perature
– Duration of buffer tank temperature deviation
– Individual setting influence on weather prognosis
The bar 2 can be used to set the level of influence for
each buffer tank individually.
0% = if the burner has started and the buffer tank is
within a release time, then the buffer tank is com-
pletely charged. The charge request is fulfilled when
the buffer cylinder temperature bottom has reached
the maximum buffer cylinder temperature bottom (in
the buffer tank main menu).(fehlender oder ungültiger
Codeausschnitt)
100 % = if the burner has started and the buffer tank
is within a release time, then the buffer tank is not
completely charged. The charge request is then
already fulfilled when the buffer cylinder temperature
bottom has exceeded the minimum buffer cylinder
temperature top (in the buffer tank main menu).
