The Hunter PSR22 is built to work with standard irrigation controllers, providing a rugged, easy-to-wire interface between 24V control signals and 120\/230 VAC pumps. Its compact footprint and flying wire leads make installation straightforward whether you are retrofitting an existing system or adding a new pump start capability.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the PSR22 integrate with my irrigation controller?\u003c\/h3\u003e\n\u003cp\u003eThe PSR22 accepts the 24VAC control signal commonly used by irrigation controllers and switches the higher-voltage pump circuit. It mounts near the pump or inside a controller enclosure and uses flying leads for fast connections. Designed as a double-pole, single-throw device, it isolates both hot conductors of the pump circuit for safe operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConnects to standard 24VAC valve output from most irrigation controllers\u003c\/li\u003e\n  \u003cli\u003eFlying wire leads simplify hook-up without extra terminal blocks\u003c\/li\u003e\n  \u003cli\u003eDouble-pole switching isolates both live conductors for safety\u003c\/li\u003e\n  \u003cli\u003eCompatible with typical controller programming and run schedules\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat pump sizes and voltages can PSR22 handle?\u003c\/h3\u003e\n\u003cp\u003eThe PSR22 is rated to control 120 VAC pumps up to 2 HP and 230 VAC pumps up to 5 HP, covering the most common residential and light-commercial booster pumps. Choose the correct model based on your pump voltage and motor size to ensure reliable starting.
