2.6 Systems
System 1: Standard solar system with 1 store
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.
