System 6: 2-store solar system with pump logic
The controller compares the temperature at sensor S1 to the temperatures at
sensors S2 and S4. If the measured temperature differences are higher than the
adjusted switch-on temperature differences, the pump (R1 and/or R2) will be
activated and the corresponding store will be loaded up to the adjusted store
maximum or set temperature respectively at most. The priority logic effects prior
loading of store 1.
