Arrangement 1: Standard solar system
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 (DT O), the solar pump will be activated by relay 1, and the store will be loaded until the switch-off temperature difference (DT F) or the maximum store temperature (S MX) is reached.
Sensors S3 and S4 can optionally be connected for measurement purposes. S3 can optionally be used as the reference sensor for the store emergency shutdown op-tion (OSEM).
