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.

A heating circuit return preheating 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). For this purpose, relay 2 will operate the
3-way-valve.
