RS485 COMMUNICATION (SYSTEM SERIAL)
This is the communication bus between the various elements that will make up the VMF system. The communication is supported by Standard RS485 via the RTU standard
ModBus communication protocol (8N2).
The network has a single master (VMF-RCC Panel) and a variable number of slaves:
— Max 10 master fan coils with VMF-E1/E18/FCL/T-TOUCH controls
— Max 3 MZC
— VMF-DHW domestic hot water power board
— A heat pump (with Modu_Control, GR3, pCO5+ control board) or the MULTICONTROL system
— Max 4 VMF-CRP expansions (Boiler/Recovery units and Circulator pumps)
— Max 3 VMF-REB expansions for radiant head control
The maximum length of the physical connection will be identified as follows:
— 1000 m with transmission speed equal to 19200 bit/s
