V5 X VRF 50/60Hz
1.2.3 Addressing mode setting
The V5 X supports two addressing modes, auto addressing and manual addressing:
 If an indoor centralized controller (CCM03, CCM09 or CCM30) is connected directly to the master outdoor unit's X Y E
terminals, the master unit must be set to auto addressing mode. If the installation situation requires that the indoor
unit addresses are set manually, first set the master unit to manual addressing mode then use a remote or wired
controller to set the indoor units' addresses one by one, and then change the master unit to auto addressing mode.
(Changing to auto addressing mode will not affect indoor unit addresses that have already been set manually).
