The controller compares the temperatures at the collector
sensors S1 and S5 to the store temperatures at the sensors
S2 and S3. If one of the measured temperature differences is
higher than the adjusted switch-on temperature differences,
the corresponding pump (R1, R2) or both pumps will be activated and the corresponding store zone will be loaded
up to the adjusted maximum temperature via the valve (R3).
The priority logic effects prior loading of the upper zone
of the store.
