14 Modular configuration units
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 of the master unit must be reinstalled on the common
supply line from all units, as far away as possible.
