System 2: 4 modular generators with hot water production
Application
Direct delivery heating with at most 4 modular generators with hot water production via
diverter valve.
Key:
C1 - C2 - C3 - C4 = Modular generators
V1 - V2 - V3 - V4 = 3-way valves
B = Boiler
VD = Diverter valve
T3 = External sensor
When the system is producing water for domestic use the sequence governor will always
control just one generator for this function, which in the diagrams of Fig. 12a - 12b is C1
