(The priority setting of operation mode means the sub wired controller can only set the specified mode after the main
controller sets operation mode, and refer to the table below for the setting mode. The priority setting of operation mode
and setting temperature means that the sub wired controller can only set the specified mode after the main controller sets
operation mode. After the main controller sets the temperature, the sub wired controller will automatically synchronize to
the same temperature.)

The wired controller with high priority is the main controller, which can limit the operation mode of the sub
wired controller and determine the setting temperature of the sub wired controller. The user can set the main
and sub wired controller freely by changing the priority of the wired controller.
If there is no main controller in a system, the system will automatically specify a main
controller after power on, but the priority will not be set up. If users want to set up a main
controller with high priority, the setting can be made based on the following method:
1. Set [Time ON]
2. Set [Time OFF]
3. [Timing Query]
1. Alarm Query
2. Alarm deletion
TIPS：
● If TIME ON and TIME OFF are both set, then the operation interface will display ON and OFF upon successful settings.
If only TIME ON is set, the operation interface will display ON upon successful setting. If only TIME OFF is set, then the
operation interface will display OFF upon successful settings.
TIPS：
● 30 alarm messages can be recorded at most in the wired controller alarm query.
TIPS：
● After starting the lock, any keypad in the keypad area is invalid
(except for lock hot key), and only the backlight can be lit.

TIPS：
● The priority settings are only performed when operation is stopped.
● The priority settings are dependent on the indoor unit model, and the main-sub settings are not supported in
individual cases. Please consult the local distributor for more details.
If there are other main controllers inside the system already, users can set up according to the
method below if want to assign a new main controller:
