System 9: Solar system with 1 store and return preheating
The controller calculates the temperature difference between collector sensor S1
and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference, the pump (R1) will be switched on and the store
will be loaded until the switch-off temperature difference or the maximum store
temperature is reached.
With another temperature differential function (S3 heat source/S4 heat sink) return
preheating (heating circuit backup) is possible via another valve (R2).
