System 22: Solar system with store loading in layers and east-/west collectors
The controller compares the temperatures at the collector sensors S1 and S5
to the store temperature at sensors S2 and S3. If one of the measured temper-
ature differences is higher than the adjusted switch-on temperature difference,
the corresponding pump (R1 and/or R2) will be activated and the corresponding
store zone will be loaded up to the adjusted store maximum or set temperature
respectively via the valve (R3). The priority logic effects prior loading of the upper
zone of the store.
