System 14: Solar system with store loading in layers and return preheating
The controller compares the temperature at sensor S1 to the temperatures at
sensors S2 and S3. If the measured temperature differences are higher than the
adjusted switch-on temperature differences, the pump (R1) 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.
With another temperature differential function (S5 heat source / S4 heat sink) re-
turn preheating (heating circuit backup) is possible via another valve (R2).
