Outputs
T1…. Flow solar loop
A1…. Primary solar pump
T2…. Tank TK1
A2…. Solar pump TK1
T3…. Tank TK2
A3…. Solar pump TK2
T4…. Tank Tk3

Program C0:
Function according to diagram.
The primary and the secondary side are sepa-
rated hydraulically. The secondary pumps are switched separated from the primary pumps.
