Actual power from solar heat meter [kW]
Display of the current output which is generated by the
solar collector. The calculation of the output is only
performed either when a per litre output of the collector
pump has been set or an external volume pulse
transmitter is used. In order to perform the calculation
more precisely, the use of a collector return sensor is
recommended.
Flow through [l/h]
Prerequisite: External volume pulse transmitter installed
Display of the water quantity currently being pumped
through the solar collector.
Todays yield [kWh]
Display of the heat quantity that has been supplied by the
solar panel system today.
Daily yield 1 ... 6 days ago
Shows the historical progression of the solar panel
system. The yields of the last 6 days are available.
Total yield [kWh]
Display of the heat quantity which has been supplied by
the solar panel system since activation of the heat meter.
Nominal flow of collector pump for heat meter [L/h]
If no external volume pulse transmitter is used, the pump
of the heat meter can be activated by entering the per litre
output. The flow rate at 100% collector pump speed must
be entered here.
NOTICE!This parameter can be ignored if using an
external volume pulse transmitter!
Litres per pulse of flow through meter
If an external volume pulse transmitter is used, adjust this
value according to the volume pulse transmitter used [0.5
– 5 pulses/L].
Sensor input of the collector return sensor
Sensor input to which the sensor for the collector return is
connected.
Sensor input of heat meter flow temperature
sensor
Sensor input to which the sensor for the heat meter flow
temperature is connected.
Is an external flow meter used?
▪ YES: An external volume pulse transmitter is in use.
Total yield [MWh]
Display of the heat quantity which has been supplied by
the solar panel system since activation of the heat meter.
Collector flow temperature
Indicates the temperature of the sensor in the flow to the
collector. This can optionally be configured and is
necessary for measuring heat quantity. Is no flow
temperature sensor is configured, the collector
temperature is used.
Heat exchanger sec. return temperature (line to
buffer tank)
Prerequisite: System 12 or System 13
For solar systems with an external heat exchanger, the
outlet temperature from the heat exchanger is recorded as
a secondary measurement.
4.4 Buffer tank
4.4.1 Buffer tank - Status
Buffer tank top temperature
Display of the current temperature in the top part of the
buffer tank.
Storage tank temperature sensor 2 … 7
Prerequisite: Multi-sensor management with 3 – 8
sensors
Displays the current temperature at the respective sensor
position at the storage tank. All of the configured sensors
are used to calculate the storage tank charge status.
Buffer tank middle temperature
Prerequisite: Middle buffer tank temperature sensor
installed
Display of the current temperature in the mid area of the
buffer tank.
Buffer tank bottom temperature
Display of the current temperature in the lower part of the
buffer tank.
