The Irritrol RD1200-INT-R Rain Dial-R is a twelve-station indoor irrigation controller for larger residential and light-commercial systems installed in a garage, utility room, equipment room, or another dry location. It provides the highest station count in the standard Rain Dial-R family while retaining familiar local programming and support for optional Irritrol weather, remote-control, and connected-management accessories.
Three independent programs allow turf, shrubs, drip irrigation, and specialty plantings to use different watering days, start times, and station assignments. Each program supports three daily start times for up to nine total starts. Station run time can be set from 1 to 59 minutes in one-minute increments or from 1.0 to 5.9 hours in six-minute increments. Water budgeting, monthly percentage presets, odd/even scheduling, skip-day intervals, excluded days, station delay, test-all-stations operation, and assignable pump/master-valve control support complex properties without requiring a commercial central-control platform.
The controller includes a rain-sensor input and is compatible with optional Climate Logic weather sensing, SMRT Logic remote access, and CRR handheld remotes. These accessories are sold separately. A 9-volt alkaline battery, also not included, supports armchair programming and maintains time and date during power interruptions.
