The loading of the tanks is authorized if the temperature
difference "dt" between the collector (T1) and the tanks
(T2, T3) is sufficient.

3.2.4 System 4.
System with 1 tank, 1 pump, 1 valve, 2 collector arrays
with 2 different cardinal direction (ie. East / West) and

The loading of the tank1 is authorized if the temperature
difference "dt" between collector (T1, T4) and the tank1
(T2) is sufficient. The valve direction (P2) is done by the
warmer collector.
3.2.5 System 5.
System with 1 collector array, 1 solar tank, 2 pump. With
this system you can not add an extra function.
T1

This system allows warming the hot water by solar tank 1
or by two additional boilers. The P2 and P3 contacts are
used to do this function. You will have the possibility to
adjust different levels for loading priority.
