Reliable battery-powered irrigation control for valve boxes and remote sites. The HydroRain HRC 990 4-station controller delivers tool-free, wire-free operation for small residential and light commercial systems where AC power or trenching isn't practical. Its intuitive dial programming and plug-in valve connections speed installation and reduce service time.

  • Battery operation: runs on three AAA batteries (included) for quick, wire-free installs and low maintenance.
  • Expandable modular design: base unit includes one 13V DC latching solenoid and accepts up to four DC solenoid modules for up to 4 stations.
  • Advanced scheduling: two independent programs (A/B) with up to four start times per program, plus odd/even, interval, and weekly scheduling options.
  • Water-saving features: programmable rain delay (24/48/72 hours) and seasonal water budgeting from 10% to 200% without changing individual run times.
  • Durable and waterproof: IP68-rated submersible design works properly submerged up to 3' (1.2 m) and operates from 32°F to 167°F (0°C to 75°C).
  • Sensor and solar-ready: add the moisture sensor module or solar power module to enable sensor-driven or solar-charged operation; programming remains stored during brief battery changes.

Compact, plug-and-play wiring and broad valve compatibility make the HRC 990 simple to install and service in valve boxes, manifolds, or remote locations. Backed by a multi-year warranty, this controller offers a durable, flexible solution when burying wire or using mains power is not an option.
