Special RC-7 constant pressure water supply machine
Product Details
RC-7 constant pressure water supply machine is based on the RC-9 of the underlying hardware, the new development of the motherboard, operation panel and special software. The operation panel can set pressure and display pressure, which is convenient for users to adjust. Sleep and wake-up pressure custom settings, for a slightly leaking water supply system, you can still sleep normally. Using 485 communication to realize multi-machine interconnection, the system wiring is simple, macro parameter setting, convenient debugging, can realize the function of automatic wheel pump, and has water shortage protection, overpressure protection, sensor disconnection protection, overcurrent protection, etc.
