Main Features：
◆ Sleep Function：No water consumption pump decelerates to the lower limit and after a detection then sleep down. Until the pressure below settings, master wake up automatically.
◆ Restarts After Power on：Power off during running, it restarts when power on again
◆ Anti clogging Function：Just designed for single pump, the pump run REV/FWD alternate.
◆ Day-Part Control：Split one day into several day-part to run a private pressure respectively. Considered input side water pressure limit, once input water pressure is less than setting pressure, stop running; while up to setting, recover running.
◆ Terminal Run/Stop：Can be lead to external switch from terminal. When switch on, pump run and maintain a setting constant pressure; when switch off, pump stopped.
◆ Electric contact Control：Two terminals switch on COM instruct the controller to accelerate and decelerate respectively. Can used for realize the pump running in a switch setting pressure range.
◆ Electrical fault protection: When there is an over current, over voltage, under voltage, phase loss, over load etc, the controller will alarm and stop automatically.
