Rain Bird “The Intelligent Use of Water" Review: Easy to set up and program. - Replaced the previous older version of this controller which had digital push buttons. Had a new lawn installed recently. It was perplexing and difficult to program the auto-runs and two-a-days. Was able to quickly install and program this newer model. Very user friendly! Price was a little higher than I expected. desertcart delivered the next morning, so happy! Review: Great Priced Sprinkler Timer - Very easy to setup and install. The instruction were clear and made it very easy. It’s a simple and modern sprinkler timer in one. The cost of the timer is very good and competitive. The quality of the timer is top notch as in all of Rain Bird products. It connects to all my zones and wires perfectly. The weather monitoring is very good and matches the high end timers. ## Features - This timer is so easy to program you won't need the instructions - Simple zone-by-zone settings allow customized watering schedules for each area of your yard - Designed for indoor installation within a garage, home, or waterproof shed - One-touch seasonal adjust allows increase to watering time in hot, dry months or reduction in cool, rainy periods - Rain Delay suspends watering for up to 72-hours; when delay ends programming automatically resumes - Superior long-lasting durability and built-in surge protection - Sealed case to protect against moisture, insects and grime - New and Improved model SST400IN timer replaces the Obsolete SST400I ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071QWPWY5 | | Best Sellers Rank | #7,636 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #11 in Automatic Irrigation Controllers | | Brand Name | Rain Bird | | Color | Gray/Green | | Customer Reviews | 4.6 4.6 out of 5 stars (4,660) | | Display Type | LCD or LED | | Included Components | Timer, CR2032 lithium ion backup battery, user manual | | Item Dimensions L x W x H | 19.25"L x 19.25"W x 2.5"H | | Item Type Name | Rain Bird SST400IN Simple-to-Set Indoor Sprinkler/Irrigation System Timer/Controller, 4-Zone/Station (This New/Improved Model Replaces SST400I) | | Item Weight | 16 ounces | | Manufacturer | Rain Bird | | Material Type | Plastic | | Model | C50407 | | Operating Temperature | 68 Degrees Fahrenheit | | Part Number | SST400IN | | UPC | 077985004644 | | Unit Count | 1.0 Count | | Voltage | 120 | | Warranty Description | Warranty. | ## Product Details - **Brand:** Rain Bird - **Color:** Gray/Green - **Material:** Plastic - **Product Dimensions:** 19.25"L x 19.25"W x 2.5"H - **Voltage:** 120 ## Images ![SST400IN - Image 1](https://m.media-amazon.com/images/I/81qRZVJ43CL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to set up and program. *by L***A on March 22, 2026* Replaced the previous older version of this controller which had digital push buttons.
