7.3.3 Signal wire of centralized control
Signal wire of centralized control
When centralized control is needed, one CCM03 (central controller of indoor unit) can only control the
indoor units which are in the same refrigerant system
via the port X Y E of outdoor unit.
Outdoor unit
will automatically distribute the address to indoor units without any manual setting. Remote controller
can enquiry and modify every indoor unit address.
The diagram below shows the connection of signal wire in this case:
Besides, CCM03 can also connect indoor units
via the port X Y E of indoor unit
. However, one more
group of wire(X Y E between indoor units) is needed; it is more complex and not suggested. Anyway, the
diagram below shows the connection of signal wire in this case:
