Products Features: Dynamic Shape: Streamlined design with intelligent technology it gives Dynamic Shape. Delay Startup: The pressure controller delays to start 3 seconds after the current is switched on to protect the pump and personal safety. Dry running protection: After 3 minutes usages without water, the controller will cut off current source automatically. Automatic restart: Circulate by time, automatically restart to test water flow until water supply going stable. Stop water supply and stop the pump: When stopping water supply, the intelligent control system will inspect automatically and control the pump to slow down and stop operating Flow Control: When the outlet water flow becomes slow, the intelligent control system will inspect automatically and switch to small flow control system to guarantee normal use of the water pump, which infinitely extends the life span of the controller and automatically realize the barrier free operation of water pump. Overload Protection: The intelligent system is equipped with heat overload protector to prevent water pump being overheated and damages under abnormal use.
