Wiring example of centralised control systems
• Be sure to connect the wiring of the central controller to (A) or (B).
(Connect to (B), if it is possible.)
• Be sure to limit the number of indoor units within the limitation for each system.
• Never connect the wire between the controllers, that are connected to different circuits.
• In order to prevent the connection of 3 wires on the same terminal, connect to the terminal unit of (A) or (B), or use the relay terminal
(local supply).
4 • When all centralised control systems are located at one place.
