System 5: 2-store solar system with valve 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) will be activated and
the corresponding store will be loaded up to the adjusted store maximum or set
temperature respectively via the valve (R3). The priority logic effects prior loading
of store 1.
