WM10 low loss header module

The WM10 low loss header module regulates the
hydraulic separation between the boiler and the
consumer circuits. This hydraulic separation can be
achieved with a low loss header or via a heat exchanger.
In addition, the WM10 low loss header module can
actuate the secondary pump for the heating circuit
without mixer (heating circuit 1) (system
examples page 70 f.). Furthermore, the WM10 low
loss header module offers the option of heating DHW via
a cylinder primary pump. When actuating a cylinder
primary pump, heating operation with one heating circuit
with mixer is possible parallel to DHW heating (system
example page 71).
In systems with Logamax plus GB162 gas condensing
boilers, hydraulic separation is generally required if two
heating circuits are to be connected with individual
pumps.
