System layout 2

The controller calculates the temperature difference bet-

ween collector sensor S1 and tank sensor S2. If the diffe-

rence 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.
