Vitotronic 300: "Energy statement" of the boiler in conjunction with solar thermal system
You can call up the energy status for the last 7 days,
including the current day. The amount of heat gener-
ated from solar power and the energy consumption of
the boiler (gas or oil) are shown in kilowatt hours
"kWh".
Note
This information can only be retrieved in conjunction
with the solar control module, type SM1.
Tap the following on-screen buttons:
1. If required, for the home screen
Vitotronic 300: DHW cylinder temperatures
You can call up the current DHW temperatures in the
DHW cylinder ("Heat-up condition").
Tap the following on-screen buttons:
1. If required, for the home screen
Energy consumption and operating data
You can call up the following information about your
boiler:
"Current output" (heating output)
■
"Hours run" (operating time)
■
■ "Fuel"
■ "Fuel consumption" (energy consumption)
Tap the following on-screen buttons:
1. If required, for the home screen
2. / for the "Energy cockpit"
3. in conjunction with a gas boiler
or
in conjunction with an oil boiler
The operating data is shown, e.g. the "Hours run"
Note
To reset the hours run: See chapter "Calling up
information".

3. in the navigation area
The "Energy statement" is displayed as a
graphic.
Blue: Amount of gas consumed
or
Dark yellow: Amount of oil consumed
Light yellow: Amount of heat generated by the
solar thermal system
2. / for the "Energy cockpit"
3. Tap the DHW cylinder
5. Tap the required period:
"The past 7 days", including current day
"The past 5 weeks", including current week
"For the past 12 months", including current
month
"For the past 2 years", including current year
Consumption above or below these levels is shown
graphically within the selected time period for com-
parison purposes:
Dark areas: Proportion of energy consumption
for central heating
Light areas: Proportion of energy consumption
for DHW heating
6. Tap e.g. a day or a week on the graph. The energy
consumption for this period is shown as a numeri-
cal value in kilowatt hours "kWh". 10 kWh corre-
sponds to approximately one litre of fuel oil or one
cubic metre of gas.
Information on the energy consumption figures
shown
The calculation of the energy consumption takes into
account the installed system components and the user
behaviour (e.g. operating time and utilisation level).
Depending on system-specific conditions, differences
may arise between the displayed (calculated) and
actual consumption figures.
They therefore cannot be used as a binding basis for
billing with the power supply utility.
