System 14: Solar system with 1 collector field, swimming pool heating
Description:
The controller calculates the temperature difference between collector sensor T1 and
swimming pool sensor T2. If the difference is larger than or identical to the adjusted
switch-on temperature difference, then solar circulation pump (R1) will be switched on, and
swimming pool will be loaded until the switch-off temperature difference or the maximum
swimming pool temperature is reached.
