Functions
If only one air conditioner is used, the controller provides logic control of components in
the air conditioner to meet temperature and humidity requirements.
By integrating a compressor frequency-converting drive, the controller adjusts the
frequency of the DC frequency-converting compressor to adapt to load changes and
enables you to query the settings and status of the compressor.
The LCD on the controller allows you to set the parameters for the air conditioner and
query its status.
If multiple air conditioners are used, the controller optimally distributes the heat load to
reduce power consumption and provides backup to improve reliability.
Features
The controller provides a touchscreen with a user-friendly interface.
The controller controls the air conditioner precisely and responds quickly.
The multi-level password protection prevents misoperations.
The controller protects the air conditioner against overvoltage, undervoltage, abnormal
power failure, and water leaks, which ensures air conditioner reliability.
The LCD on the controller displays the operating status and duration of the air
conditioner components in real time.
The fault diagnosis system automatically displays the information of the current fault,
which facilitates the maintenance.
The air conditioner provides abundant external ports such as RS232 ports, RS485 ports,
fast Ethernet (FE) ports, and USB ports that are protected by a security mechanism.
2.3.2 Monitoring System
The monitoring system provides logic control, data collection, control delivering, alarm
reporting, data storage, user right management, and group control. The air conditioner can be
connected to the monitoring system over a northbound port (RS485 or RS232) for remote
management.
