This indoor-mounted timer is so easy to use you can forget the instructions. Its intuitive zone-by-zone scheduling allows you to set watering times differently for each area of the yard, providing greener results with less water. By turning the dial to each zone, you can easily set more or less watering for full sun and shaded areas, or water slopes and clay soils in short intervals to allow water to soak in, avoiding runoff. You can also set different timing and frequency of pop-up sprays vs. rotor zones and customize watering of trees and landscaped areas in Drip zones. Each zone’s setting can be reviewed easily in one view with a turn of the dial.

  • Controls up to 9 valves
  • Simple zone-by-zone setting allows you to customize watering schedules for each area of your yard
  • No complex programming – just turn the dial to a zone, then choose start time, watering duration and days of week
  • Large easy-to-read screen and lighted buttons allow you to review settings at a glance
  • One-touch seasonal adjustments allow you to increase watering in hot, dry months and reduce it in rainy periods

  • Color coded terminals make it easy to connect zone wires as well as master valves, pump start relays or a rain sensor
  • Includes timer, transformer with 6-ft cord plus installation guide

Rated 4.2 out of 5 by 41 reviewers.
Rated 4.0 out of 5.0 by A few tricks to make programming even easier Very easy to install and program, but the manual isn't clear on a few things. 1) You should set all the zones to start at the same time if you want them to run in sequence. This way you can easily use the seasonal adjustment to run longer or shorter. 2) If you want to run twice per day, you DO have some control over the interval. Current options are +1, +2, +3, +4, +6, +9, +12. You just push the 2 times per day button to cycle through the options. There isn't a battery backup, but the unit holds its programming during a power failure, although the clock will need resetting. May 7, 2014
Rated 5.0 out of 5.0 by Simple and Easy It was just as easy as the information about the product said to setup and use. With my old unit I was having problems with it consistently working. The Rainbird does it all and has been flawless. I'm happy that I bought it and it was easy to hook up by myself. April 14, 2015
Rated 5.0 out of 5.0 by Rain Bird9-Station SST900i Indoor I'd buy it again, easy install, easy programing with many programing options. May 19, 2015
Rated 5.0 out of 5.0 by Great Simple Irrigation Timer Replaced a mechanical timer with this electronic version. The wiring was simple and straight forward. Once installed setup and testing was again as simple as it could be. This Timer allows many different ways to set irrigation times with multiple on same day, alternating days, or any single or multiple days in a week. Timer has been installed and working about three weeks and there have not been any issues. June 30, 2015
Rated 4.0 out of 5.0 by Very nice improvements. Some good thought went into the engineering of this unit. The settings have not only been expanded, they are certainly simpler overall, and the progression of steps involved are much more logical and easy to remember. I almost never give the maximum rating possible, but the only thing that stopped me this time is, I wish it had a cover to make it look a little more refined for outdoor, in the weather usage. After several weeks of use and modifying settings, I have only good experiences. June 19, 2015
Rated 5.0 out of 5.0 by Makes Programmed Watering Easy Very simple to install and program. Provides full flexibility for each zone. Price and quality are top notch. June 30, 2015
Rated 5.0 out of 5.0 by Plug and Play - Works Beautifylly! The product was easy to use. Required minimal experience to install and works as expected. June 30, 2015
Rated 5.0 out of 5.0 by Easy install and programing With new water restrictions I need to replace my 20 year old controller. I can only water on Tuesday Thursday Saturday. The new controller was easy to install and program. Was able to have it up and running in less than an hour June 6, 2015
