When a blockage occurs in the main drain or skimmer a sudden rise in vacuum will cause to shut down pump operation and activate an audible alarm. The pump will remain off with the alarm sounding until manually reset. It act as pool controller with programmable timer, or as stand alone SVRS working in conjunction with existing pool controller. Newest state-of-art NEC microprocessor technology guaranteed reliability and performance. Vacuum monitored 128 times per second rapid response and accurate readings. Power monitored 50/60 times per second insures continuous power detection.
Can act as a pool and spa controller - with fully programmable 24 hour timer, or as stand alone SVRS working in conjunction with existing pool and spa controller. Integrates with existing timer box for easy retrofit. Low vacuum sensing prevents cavitation's or running the pump dry, eliminating costly equipment failure. 30 minute maintenance override. Accessible extra dry contact auxiliary equipment can be added. Power back-up insures settings and reading will be saved (30 minute rapid recharge). Display error readout (prevents guessing during troubleshooting). Works on all size pumps. Easy and trouble free installation - (no pipes to cut or glue). Turns off pump in milliseconds upon detecting sudden vacuum change. Multiple audible alarm capabilities allows for quicker alert to harmful situations.
