The controller compares the temperatures at the collector sensors S1 and S5 to
the store temperature at sensor S2. If one of the measured temperature difference
is higher than the adusted switch-on temperature difference, the corresponding
pump (R1 and / or R2) will be switched on, thus loading the store until either the
switch-off temperature difference or the store maximum temperature is reached.
