15 Weatherman function
Weather influence heating circuit 1
This area is only visible when the heating circuit
obtains its energy from a buffer tank enabled in the
control.
Activate the weather influence heating circuit function
only if the buffer tank is connected to a solar power
system.
Good weather being forecast delays the start of the
burner in the event of a request from the heating cir-
cuit. 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 duration of the
request delay for each heating circuit individually.
(fehlender oder ungültiger Codeausschnitt)
0% = no delay to burner start.
100% = maximum delay to burner start in the event of
good weather being forecast.
If the function delays the burner start due to good
weather being forecast, then the weatherman icon
appears in the main heating circuit menu.(fehlender
oder ungültiger Codeausschnitt)
The green column indicates the delay. When 100% is
reached, the burner starts.
Solar yield in the room 3
Activate this function only if solar radiation directly
influences the heating circuit (e.g. solar radiation
through a glass panel).

Good weather being forecast means the following:
– The flow temperature of the heating circuit is
reduced (within the heating period) to maximum
lowering temperature
– The room temperature is reduced (if the Room
effect parameter is activated in the heating circuit
menu)
The bar 4 can be used to set the temperature reduc-
tion for each heating circuit individually
0% = no reduction in the heating circuit flow tem-
perature, or the room temperature.
100% = maximum reduction in the heating circuit flow
temperature, or the room temperature, in the event of
good weather being forecast to maximum lowering
temperature
Within the heating period, the heating circuit flow tem-
perature is reduced by a maximum of the reduction
set on the heating curve screen.
Within the heating period, the inside setpoint tem-
perature is reduced as a maximum to the inside set-
point temperature reduced mode set on the heating
circuit room settings screen.
If the Solar yield in the room function reduces the tem-
perature(s) due to good weather being forecast, then
the weatherman icon appears in the main heating cir-
cuit menu.
