System 12: Solar system with store loading in layers and thermostatic afterheating
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 (R2). The priority logic effects prior
loading of the upper zone of the store.
Afterheating (R3 and R4) can be carried out with a thermostat function (S5). If the
value at S5 reaches the switch-on temperature for the afterheating, the relay is
switched on. If the value exceeds the switch-off temperature for the afterheating,
the relay is switched off again.
