Level 5
The controller compares the temperatures at the collector
sensors S1 and S5 to the temperatures at S2 and S4. If one
of the measured temperature differences is higher than the
adjusted switch-on temperature differences, the correspon- ding pump (R1, R2) or both pumps will be activated and
the corresponding store will be loaded up to the adjusted
maximum temperature via the valve (R3).
