The controller calculates the temperature difference between
collector sensor S1 and tank sensor S2. If the difference is
larger than or identical to the adjusted switch-on temperature
difference (DT O), the solar pump will be operated by relay 1,
and the tank will be loaded until the switch-off temperature
difference (DT F) or the maximum tank temperature (S MX)
is reached.

Heat exchange from tank 1 to tank 2 will be operated by relay
2, if the temperature difference between sensors S3 and S4 is
larger than or identical to the adjusted switch-on temperature
difference (DT3O), until the adjusted minimum (MN3O) and
maximum (MX3O) temperature thresholds of the respective
tanks are reached.
