Irrigation Controller Greenmill 4-Station Model GB6964C

The Greenmill 4-Station Irrigation Controller GB6964C is a compact timer designed to automate watering for residential gardens, lawns and small landscape areas. It provides scheduled control for up to four valves or zones and supports programmable run times and multiple start times to suit different plant and soil needs. The unit is intended for surface or sheltered installations where straightforward zoned irrigation management is required.

Advantages

This controller offers simplified programming for four independent zones, enabling precise control of run durations and start times. Its compact design makes installation and wiring straightforward, while the scheduling flexibility allows users to create different watering cycles for lawns, flower beds and drip systems. The controller reduces manual intervention by automating routine irrigation, helping maintain consistent moisture levels across small to medium outdoor setups.

Suitable for

• Residential lawn irrigation
• Small garden and flower bed watering
• Drip irrigation lines for shrubs and planters
• Simple sprinkler systems with up to four zones

Key specifications

• Number of zones: 4 independent station outputs
• Programming: programmable run times and multiple start times per day
• Compatibility: designed for standard 24VAC solenoid valves used in residential irrigation
• Mounting: surface or sheltered wall installation
• Power: mains-powered with internal transformer (follow local wiring requirements)

How to use

Install the controller in a dry, accessible location close to the valve manifold and power supply. Connect each valve solenoid to the corresponding station output and ensure common wiring is correct. Set the current time and program each station with desired run time and start times according to plant water needs and local watering restrictions. Test each zone to confirm valve operation and adjust schedules seasonally for efficient water use.

Usage recommendations

For reliable performance, protect the controller from direct exposure to rain and extreme temperatures. Use quality valve solenoids rated for irrigation systems and verify that wiring connections are secure. Adjust watering durations based on soil type, plant species and weather conditions, and consider pausing or reducing schedules during rainy periods.
