The controller calculates the temperature differences
between collector sensor S1 and tank sensors S2 and S3. If
the differences are larger than or identical to the adjusted
switch-on temperature differences (DT1O / DT2O), the solar
pumps will be operated by relay 1 and / or relay 2, and the
respective tank will be loaded until the switch-off temperature
differences (DT1F / DT2F) or the maximum tank temperatures

loading of the selected tank (PRIO), if possible. Loading both
tanks simultaneously is possible as well (PRIO = 0).
Sensor S4 can optionally be connected for measurement
purposes.
