The solar panel is configurable to feed the DHW, system buffer or both the DHW and the system buffer with a configuration parameter CFG-01, as shown in the next figures.
In all configurations the solar pump can be configured as a fixed – or variable speed pump setting the parameter CFG-02.
Both the pump command and the pump speed control are available at the macro outputs. The configuration is important for the solar energy management.
