Multiple inverter basic protection functions;Water pump exclusive protection function(water shortage protection,high and low pressure protection,leakage protection,anti-freeze embroidery protection, sensor disconnection protection).
1. The pressure of the pipe network is detected by the host and sent to the auxiliary machine. When the pressure is not enough, the auxiliary machine starts and runs according to the set frequency, and the main machine performs constant pressure PID adjustment.
2. The main and auxiliary machines altemately run in sequence at regular intervals to realize the uniform use of the water pump and extend the life of the water pump.
Perfectly drive a variety of water pump motors such as asynchronous, permanent magnet synchronous, synchronous reluctance, etc.
