Function Description

1 Startup and loading

Upon powering on, the device displays a boot screen before loading the main interface. The loading process, managed by the Android system, may take some time. The System Configuration interface is accessed after loading is complete.

2 System Configuration interface

Upon entering the System Configuration interface, you will be prompted to input an account and password. The default credentials for service personnel are "admin" and "8699". The language selected here will determine the initial naming of the device.

The interface allows users to specify the city, district, address, contact person, service call number, and service email for the device's location. After inputting this information, click 'Next' to proceed to the Indoor and Outdoor Unit Search interface.

The system then initiates a search for all connected Outdoor Units (ODU) and Indoor Units (IDU). The interface displays the search progress, indicating the number of matched external and internal machines and the percentage of the search (e.g., 0%).

After the search is completed, verify that the number of indoor and outdoor units detected is correct. If the information is accurate, click 'Next/Finish' to navigate to the Home page. If the information is incorrect, click 'Search Again' on the Outdoor Unit Information interface. If you are currently in the Indoor Unit Information interface, click 'Back' (◀️) to return to the Outdoor Unit Information interface.

The interface will then prompt you to confirm the ODU and IDU information. If the details are not correct, it is recommended to check the wire connections and system settings. Click 'Next' to proceed.

Subsequently, the interface displays the confirmed IDU number and information, listing units such as Indoor Unit0, Indoor Unit1, Indoor Unit11, and Indoor Unit12. Click 'Complete' once you are satisfied with the information.

3 Indoor Unit Master Control interface

The main interface presents a list of all connected Indoor Units, displaying their names, set temperatures, fault conditions, on/off status, operating modes, and fan speeds. The current date and time are shown in the upper right corner of the centralized controller display.

By clicking on any individual Indoor Unit, you can access its specific control interface to view and adjust its set states.

Within the Master Control interface for a selected Indoor Unit, the name of that unit (or room) can be freely edited in the upper right corner.

The interface provides controls for:

• Auxiliary Function: Access to additional settings.
• Temperature setting: Adjustments using '+' and '-' buttons.
• Fan speed setting: Options include Low, Mid, High, and Auto.
• Mode setting: Choices include Cool, Heat, Dry, Fan, and Auto.
• On/off setting: Controls for turning the unit on or off (e.g., 'Opened' or 'Closed' status).

Fan Speed Selection: Users can select fan speeds such as High, Medium, Low, or Auto by interacting with the fan speed setting control.

Mode Selection: Users can choose the operating mode, including Cooling, Heating, Dehumidification, Fan, or Auto mode. It is noted that for VRF systems, the Auto mode functions as Cooling. The fan speed cannot be adjusted when the unit is in Dehumidification mode, and the setting temperature cannot be changed when the unit is in Fan mode.

4 Other functions

Clicking the circular graphic element on the main interface will reveal a setting interface, allowing access to other functions.

After selecting 'Auxiliary Function', the Auxiliary Function interface is displayed. This interface allows users to configure various settings, including:

• Lighting (?)
• Horizontal winging

• Economy Operation
• Mode Lock (?)
• Remote Lock
• Electric Auxiliary heater

Note: The availability of these advanced functions may vary depending on the specific model. Economy operation and electric auxiliary heater controls are currently reserved functions for VRF systems. Mode Lock is exclusively available on VRF systems and can lock cooling and heating modes. The system will determine whether to lock the cooling mode based on whether it is currently in a non-heating mode.

5 Zone function

The Zone function enables grouping of Indoor Units, allowing for simultaneous control of multiple units with a single action after they have been grouped. Navigating to the main Zone Function interface is done by clicking 'Zone'.

The Zone interface provides the following capabilities:

• Unfold: To display the current states of the Indoor Units within a selected Zone.
• Long press Zone name: To edit the Zone name.
• Set all Indoor Units in the Zone: To apply settings to all units in the group.
• Copy the Zone (?): To duplicate an existing Zone.
• Delete the Zone (?️): To remove a Zone.

• Create a new Zone: To establish a new group and assign it a name.
• Add Indoor Units: To include units into a Zone.
• Carry out the setting on the Zone: To apply the configured settings to the Zone.

A Zone can accommodate up to ten Indoor Units. The Zone Name can be edited by long-pressing it. The states of Indoor Units within a Zone can be expanded for viewing by clicking the '+' icon.

The editing interface is accessed by clicking a specific icon (e.g., 'edit'). Here, users can select Indoor Units from the left-hand list to add or remove them from the Zone. All Indoor Units can be added with a single click using the middle '>' button, and similarly, they can be deleted with a single click using the middle '<' button.

The Zone Setting interface allows for uniform configuration of the operation mode, fan speed, and temperature for all Indoor Units within a Zone. These settings are applied immediately by clicking 'Carry Out' after returning to the Zone Function interface.

A Zone can be copied (?) or deleted (?️) using dedicated icons.

6 Scene function

The Scene function permits the creation of up to 10 distinct scenes. Within each scene, users can define time switches, operating modes, fan speeds, and temperatures for the associated Indoor Units.

A new scene can be created and named by clicking 'Add Scene' in the upper right corner. A time switcher can be added by clicking the '+' icon on the left side.

Scenes can be configured with specific boot and shutdown times. After setting the desired times, users can click 'Choose Equipment' to add Indoor Units to the scene.

The mode, fan speed, and temperature for each time node within a scene can be adjusted by clicking the corresponding icons for Time setting, Mode setting, Fan speed setting, and Temperature setting.

Additional time nodes (up to a maximum of three) can be added by clicking the '+' icon located between the power on and off icons on the right side.

The repeat schedule for a scene can be set by clicking 'Repeat' on the right, allowing selection of specific days of the week (Mon, Tue, Wed, Thu, Fri, Sat, Sun).
