Heating circuit pump HC1 Q2
The connected pump serves as a circulating pump for heating circuit 1.
Heat circuit pump HC2 Q6
The connected pump serves as a circulating pump for heating circuit 2.
DHW controlling element Q3
Depending on the hydraulic system in use, output Q3 serves for control of a
connected DHW charging pump or diverting valve.
Suppl source control K32.
Control K32 is used together with release relay K27 to control the supplementary
source (see line 3690-3755).
