Measurement of the energy obtained
When the solar system is also used for domestic hot water heating, we want to know how much heating energy has been obtained from the solar system.
The SCC controllers allow for an informative and accurate measurement of the solar energy obtained and the display of the data in weekly, monthly and yearly diagrams.
The SCC controllers allow for an informative and accurate measurement of the solar energy obtained and the display of the data in weekly, monthly and yearly diagrams.
- For informative measurements of the solar energy obtained, the maximum reading of the medium flow from the mechanical meter must be entered in the controller setup.
- For accurate measurements of the solar energy obtained, a flow meter with a pulse generator or a Vortex flow meter (VFS) must be installed in the solar system.
Typical hydraulic connection
Solid fuel boiler, storage tank, constant return temperature control, two-stage loading.
Example: hydraulic connection 292.
