Two separate communication channels are available
Local eBUS interface:
eBUS local interface (Y1)
Allows communication with the UNICAL acquisition
and control equipment installed:
• BMM: “Burner module manager”, controls the
single Heat source: Burner or Boiler
• SHC: “Slave heating controller”, manage the
Heating circuits: CH, DHW and the auxiliary
resource: Relay and Solar application
• HCM: “Heating control manager”, coordinates the
SHC requests and manage the heat request from
a single burner or a cascade system, the HCM
device can also offers a function similar to the SHC
Modbus remote interface (Y2)
Through the
Modbus
interface is possible the access
to all the Ufly P functions.
• Acquisition of operating information of all
connected devices.
• Setting parameters and the thermoregulation
control programs of HSCP
• Diagnostic Management: Acquisition and Reset
of Alarms.
• Gateway: allows the protocol conversion of
Modbus/eBUS to access all resources connected
to the local eBUS.
Temperature sensors (Y2)
Two inputs for external temperature and ambient tem
-
perature sensors are provided: one can be used to pro
-
vide the outside temperature of the system, the other
for the implementation of the room thermostat function.
