(9) CCM Lock
♦
If receiving CCM Lock information from PC, the air-conditioners can only be central
controlled by PC. The NIM will not transfer and distinguish all remote control signals, but reject
directly. And the remote control signal from remote controller and wire controller can’t control
the running state of air-conditioners.
♦
For operation by manual switch and forced button of air-conditioner that don’t pass the
passage of remote controller, the CCM Lock is invalid.
♦
When receiving CCM Unlock information from PC, the NIM will restore to deal with and
transfer the remote control signal.
(10) Operation and State Indication of NIM Address Setting
It must be set address before using NIM. Every air-conditioner in CCM has only one CCM
address to distinguish each other. Address code of air-conditioner in CCM is set by code switch
S1 port on PCB, and the set range is 0-63.
