Central air conditioning is a converter application to save operating costs, the best way to improve the life, power-saving results in 30% of a 60%。

　　First, the application characteristics of the inverter：

　　● Sound input and output functions, analog multi-volume, the volume switch input and output for a variety of control。

　　● S485 has a Japanese communications interface can be configured integrated control system, computer network management control。

　　● Perfect protection, over-voltage, under voltage, over-current, overload, and short-circuit protection and other features to ensure safe operation。

　　● Built-in PID functionality, the use of a closed-loop temperature control, the system can detect ambient temperature, automatic air conditioning, with the weather, changes in heat load automatically, small changes in temperature, adjust quickly。

　　● Lower maintenance costs and improve service life of equipment, equipment used to extend the deadline。

　　Second, the scope of application. Apply to the air-conditioning, heating system fan, water pump, refrigerator, and other control devices, and similar to the fluid control system。
