This feature allows up to 16 units to be connected.
The system is completely controlled by the Master unit.
Each connected module is identified by an address, from 0 to 15:
the Master unit is identified as 0.
The TW leaving water temperature control probe, the flow switch
and the auxiliary electric heater must be controlled by the master
unit.
All units must be electrically connected to each other via the X-Y-
E BUS.
Each module can be equipped with an inertial system storage
tank.
Each unit with DHW option must have its own DHW storage.
An external pumping unit sized for the entire capacity of the
modular system must be provided (by the Customer). The pumping
unit will be managed by the Master unit through a potential-free
contact and 0-10V signal.
The TW probe must be installed on the supply line of the unit, as
far away as possible.
