Password verification is required upon the first startup to ensure the system security. No
password verification is required for subsequent startup if the first verification succeeds.
The controller provides multiple protection functions, such as abnormal power-off
self-recovery and water leakage detection, ensuring system reliability.
The cooling capacity, air volume, as well as the operating status and time of each
component in the air conditioner are displayed on the LCD in real time.
The controller provides abundant external ports such as RS485 ports, CAN ports, FE
ports, and USB ports that are protected by a security mechanism. These ports flexibly
meet the communication requirements and feature good electrical isolation.
O&M personnel can export fault records in one-click mode, making it easy to operate the
air conditioner and know the running status of the air conditioner.
The air conditioner supports communications protocols such as Modbus RTU, Modbus
TCP, and SNMP, facilitating connection to the network management system.
The controller intelligently identifies abnormal parameter settings (incorrect commands)
and rejects them automatically.
If the indoor temperature fluctuates beyond the normal range, an audible and visible
alarm signal is sent automatically.
