13 Weatherman function
Weather influence heating circuit
2
This area is only visible when the heating circuit
obtains its energy from a buffer tank enabled in the con-
trol.
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 bur-
ner in the event of a request from the heating circuit.
The bar
3
can be used to set the duration of the request
delay for each heating circuit individually.
0% = no delay to burner start.
100% = maximum delay to 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 heating circuit menu.
The green column indicates the delay. When 100% is
reached, the burner starts.
Solar yield in the room
4
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 that
–
the flow temperature of the heating circuit is redu-
ced (within the heating period),
–
the room temperature is reduced (if the
Room influ-
ence
parameter is activated in the heating circuit
menu).
The bar
5
can be used to set the temperature reduction
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.
Within the heating period, the heating circuit flow tem-
perature is reduced by a maximum of the
reduction
set
in 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 in the heating
circuit room settings screen.
If the
Solar yield in the room
reduces the temperature
(s) due to good weather being forecast, then the wea-
therman icon appears in the main heating circuit menu.
13.3 Domestic hot water
Fig. 2-49
1 DHW range for the boiler
octo
plus
2 DHW tank / domestic hot water area 1 to 4
Activate the
weather influence domestic hot water
function only if the DHW tank/domestic 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/domestic
hot water area.
The bar can be used to set the duration of the request
delay for each DHW tank/domestic hot water area indi-
vidually.
0% = no delay to burner start.
100% = maximum delay to 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 domestic hot water menu.
The green column indicates the delay. When 100% is
reached, the burner starts.
