of the centralized controller is turned on, all air conditioners in the network of the centralized
controller will start up compulsorily. By default, they will run in the cooling mood. The startup
and shutdown operations of the centralized controller and computer and all functional
modules will be disabled (only the command of startup is sent to the air conditioner without
affecting operation of the remote controller after startup) until the forced-on switch is turned
off.
If the foregoing two switches are turned on concurrently the emergent stop switch
shall have preference.
2.3.4 All kinds of locking states
1. Centralized controller locking
The centralized controller locking state will be recorded when powered off, re-power on it
will recover, unless receiving the unlocking order.
1) Effect
1. When the centralized controller is under locking state, it can not change the air
conditioner’s operating state through the centralized controller (such as ON/OFF the unit,
setting mode, change the setting temperature, change the fan speed, unlock the exiting
locking state etc), but it can do the query operation, until unlocking and then recover to
normal.
2. When the centralized controller is under locking state, all the air conditioners in the
centralized controller network will be locked.
2) Operation
1. Locking
Locking the centralized controller only through the computer.
2. Unlocking
a) Under the centralized controller and computer communicate normally
Only use computer to unlock the centralized controller. When unlacing the centralized
controller, the controller will send order to unlock all the controllers of all the air conditioners.
b) Under the centralized controller and computer communicate abnormally
When the centralized controller is under locking state, press “ ”key and hold
on, then press “ ”to unlock the controller (it need to re-power on the controller or press
“ ”in one minute).
The locking state of the air conditioner’s remote controller will be remained.
2. Remote controller locking
1) Effect
1. When the air conditioner is under remote controller locking state, it will not receive the
remote signals from remote controller or wire controller, until unlocking.
2. No operation for the centralized controller, it can operate the air conditioner through
the centralized controller.
2) Operation
1. Can lock or unlock through the computer.
2. Can operate by centralized controller.
In the centralized controller setting interface, press “ ” to lock or unlock. If the current state
is remote controller locking, press the key to unlock.
If no remote controller locking, press the key to lock.
3. Mode locking function
1) Effect
Under mode locking state, through centralized controller to operate the air conditioner,
