Operation and function
2.4 System: 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 (DT O), the solar pump will be activated by the
relay, and the store will be loaded until the switch-off temperature difference (DT F)
or the maximum store temperature (S MX) is reached.
Sensor S3 can optionally be connected for measurement purposes.
If heat quantity measurement (OHQM) is activated, S3 is to be used as the return
sensor.
