1. Central Control Monitor can realize
the central control and data query to
outdoor units. One outdoor CCM can
connect max 8 refrigerant system by
NIM, so each outdoor CCM can connect
max 8 systems are multiplied by max
4 sets outdoor units per system equals
max 32 outdoor units. And it adopts
wire-connecting method communication
to realize central control to the outdoor
units in the same network. .
2. CCM can communicate with PC
through RS485/RS232 converter.
One PC can connect max. 16 outdoor
CCM and 16 indoor CCM. And PC can
realize central control to outdoor units,
central control to indoor units, central
control to indoor units and outdoor units,
management, status query and so on.
