tems, the difference between the temperatures measured at storage sensor SF2 and the sen-
sor at the solar collector VF3 is determined. The 'Solar circuit pump ON' parameter deter-
mines the minimum temperature difference between sensors VF3 and SF2 required to acti-
vate the solar circuit pump. If the temperature difference falls below the value of 'Solar circuit
pump OFF', the solar circuit pump is switched off. Basically, the solar circuit pump is also
