1) LOCK: In the mode setting mode, press the lock key, and the remote controller of the
currently selected air conditioner will be locked or unlocked. The operation mode is: If the
single-machine setting is selected, the operation is performed for the air conditioner of the
current address only. If the remote controller of the air conditioner is locked currently, issue
the lock command; otherwise, send the lock command. If the single-machine mode is not
selected, and the remote controller of one or more currently selected air conditioners is
locked, issue the unlock command; if the remote controllers of all currently selected air
conditioners are in the non-locked status, issue the remote controller lock command.
When the remote controller of the air conditioner is locked, the air conditioner does not
receive remote control signals from the remote controller or wired controller until the remote
controller is unlocked. Press THE QUERY key and then press the LOCK key, and the keys
of the centralized controller will be locked or unlocked. If the keys are currently locked,
press the LOCK and keys concurrently again, and the keys will be unlocked; if the keys
are currently unlocked, press the LOCK and keys concurrently, and the keys will be
locked. If the keys are locked, pressing any key will be ineffective, except unlock operation.
In the unified setting page, press the key and the LOCK key concurrently to lock all air
conditioner modules in the network. The mode locking is cancelled when the key is pressed
again.
Note: When locking or cancelling lock, the corresponding icon indication appears or disappears
only after all the attached air conditioners are set completely, so it takes a time period. When there
are many attached air conditioners, please wait patiently.
