Product Description

HRC 990 Battery Operated Controller

Once again, Hydro-Rain is setting a new standard in irrigation technology with battery powered controllers. The HRC 990 is designed for difficult situations where buried wires are not possible. This unit is enclosed in a watertight housing making it perfect for valve box installation. The HRC 990 is easily removed from the protective housing for out of the valve box programming. The HRC 990 is compatible with Hydro-Rain® HRB, HRJ, HRV and many other brands with proper adapters. Simply remove the 24VAC solenoid on the valves and install the HRC 990 DC solenoid. Can connect up to four DC valves, moisture sensor and even a solar power module (all sold separately).
