REQUIREMENT
• For the central control line (L1) when U-series outdoor units and outdoor units other than U-series are connected
to the central control device, follow the communication wiring specifi cations for outdoor unit other than U-series.
• Using the same wire type and size, wire each line below.
If the different wire types and sizes are mixed in each line, communication trouble is caused.
• Central control line and wiring between indoors and outdoor units other than SHRM-u and U-series
• Uv line (wiring between indoor and outdoor units) and Uc line (wiring between outdoor and outdoor units) in
SHRM-u and U-series
• Wiring between outdoor and outdoor units other than SHRM-u and U-series
• For communication wiring specifi cations for outdoor unit other than SHRM-u, refer to the Installation Manual
attached to the outdoor unit to be connected.
