Level 5
The controller compares the temperatures at the collector
sensors S1 and S5 to the temperatures at S2 and S3. 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 zone will be loaded up to the adjusted
maximum temperature via the valve (R3). The upper store
zone is be loaded with priority. Heat exchange from store
1 to store 2 (R4) is possible with another temperature
differential function (S3-heat source/S4-heat sink).
