Rain Bird SST400IN Simple-to-Set Indoor Sprinkler/Irrigation System Timer/Controller, 4-Zone/Station (This New/Improved Model Replaces SST400I)

Swapped this out for a very old controller in my garage from 1991. No problems. Easy to hook up. Pretty easy to figure out how to program this one too since it's all buttons and a dial on the front. Some people like the newer style ones with a touch screen and an app that you can put on your phone but I did not care about all that.

I purchased this Rain Bird timer because It is an exact replacement for the one that broke. The install was easy and no modifications. Was glad to see that it was still manufactured. First one lasted approximately 10 years and the controls are easy to work. What I especially like about this controller is that it is not complicated, very straight forward.

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.

I have had this for about 2 weeks now, psyching myself up to install it. I must have watched a dozen videos at this point. Finally, decided to do it today and all in all, it was do-able and it works, which would be 5-star. But the instructions, although clear, made it more difficult. Typically people are replacing an existing system and have a jumble of wires to work with. And so installing the panel on the wall first was actually very difficult for getting the wires to go into numbered spaces. I would recommend people go ahead and get the majority of the wires in first (except for the three above the screw; leave those to be completed last after it’s installed on the wall). I also did plug it in to make sure it worked but did not plug it in for good until after I had the wires all hooked up. So due to the unnecessary difficulty with installing the wires and the fact that it’s only been installed for 3-hours so no experience with functionality, I deducted a star. But I expect it will work out fine and the zone set up was VERY easy. I am pleased that we didn’t pay a contractor to replace it. Even at the height of difficulty, I scoffed at that cost!

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. Amazon delivered the next morning, so happy!

This was used to replace a 20 year old Rain Bird controller which was similar in function. This unit, however, is much simpler to program and meets all the requirements I need for a controller including a rain sensor connection. It also has a 72 - hr delay switch which can be useful for reducing excess watering. It would be nice if it could be activated remotely but probably not cost effective to have a wifi connection for this one function. Looking at all the wifi connected controller reviews seems to indicate many people had problems making them function properly.

The unit arrived as scheduled and was well packed. It was heavier thanI expected, because the power transformer is heavier than expected. You need a sturdy outlet. Unfortunatley, it is an old school 24 VAC transformer, so it is heavy. The unit is nearly a direct replacement for our 30+ year old controller....but with a few new features. I decided not to go with a WiFi enabled unit since they are more expensive, and from the reviews it sounds like the WiFi interface are not robust and connections are often dropped. This unit is easy to wire up, and it worked first time. Some other comments: When reviewing the programming, you can visually see what days each zone is turned on. Nice feature . There is no covering door which makes the control more accessible, but they controls are exposed. (We'll see if the rotary knob get sticky in the garage after a few years.) The solenoid control wires go into the bottom of the unit and aren't well protected. I made a 3D printed housing to channel the wires and keep tem protected. Finally, since there is no cover door, there is not an easy place to put the zone watering schedule. Otherwise, this unit is a good replacement sprinkler controller. A good buy for the price point.

I watched the video a day prior to it arriving and took the old unit off the wall and labeled the zone wires by color. When it arrived it was installed in LESS than a half hour. Could not have been easier to install and program.

Keep track of the wiring to simplify the install and it will be easy to install. Works well and easy to operate.

Not meant for Europe. It is 110 Volt.

When you buy this product to use in India, you should separately purchase 230VAC to 110V AC step-down adaptor (power supply unit) or a 24VAC Power supply unit which can directly connect to the controller . The Controller in put power is 24V AC . This Product comes with 110VAC 60Hz to 24V AC 60Hz stepdown adapter which will suit for US distribution . This controller having self battery back up feature, in case of power failure the settings / date will not change is an advantage from previous version . Easy to set and user friendly controller .
