Take full control of your pump-fed irrigation system with the Orbit® 1-2 HP Pump Start Relay, engineered to automatically synchronize your irrigation pump with your sprinkler controller for reliable, hands-free watering. Whether your water source is a well, pond, or bore hole, this relay bridges your controller and pump so both operate in perfect coordination every time a watering cycle begins.

The relay supports 120 VAC pumps up to 1 HP and 240 VAC pumps up to 2 HP, with a 25A contact rating at 240V, making it suitable for a wide range of residential and light commercial pump installations. A 24 VAC coil connects the relay to the pump or master valve terminal on your sprinkler controller using standard AWG 16-24 sprinkler wire. The water-resistant ABS enclosure is built for outdoor durability and features conduit knockout plugs for clean, code-compliant wiring runs.

Installation is straightforward — mount the relay box at least 5 feet from your controller using the included mounting template and No. 8 hardware, connect your AC power wires (AWG 12 recommended), and wire the 24V leads to your controller's pump terminal. The relay is compatible with Orbit, Hydro-Rain, B-hyve, and Husqvarna Automatic Irrigation Controllers. UL and CUL approved for safe installation. For outdoor irrigation use with cold water only.
