Wiring Example
Example of Control Wiring
• Be sure to connect the wiring of the centralized control equipment to control wiring between outdoor units.
When wiring connections are made between indoor and outdoor units, there may be cases where control over normal systems may
become impossible if one of the connected systems should happen to fail.
• Be sure to prevent the connection of three wires on the same terminal.

The advantages when the centralized control equipment are connected to A.
• If the centralized control equipment are connected to A, it is still possible to have a centralized control, even if the power supply of
other circuit connected to the centralized control equipment is shut off. (even if the power is shut off due to long vacation etc.)
Caution:
★
1. It is not recommended to connect the centralized control equipment on (a1), (a2), (a3), as there is a risk to loose control over all
systems.
Ex.; If intelligent Touch Manager (iTM) is connected on (a1), and System1 shut down, control over System2 and System3 units is lost.
• When all the centralized control
equipment is located at one place.
