2.2.2 Hydraulic module
The hydraulic module makes the connections of sensors and pumps available for the hydraulic components of
the system (buffer tank, DHW tank etc.).
A hydraulic module is included in the delivery as standard (address 0). A further seven modules (addresses 1 to
7) can be retrofitted.
You must ensure that the module address is assigned correctly! Ü "Setting the module address" [}31]
