From the Manufacturer
Add more value, versatility and convenience to your automatic underground watering system with a Rain Bird SST Series Automatic Sprinkler Timer. Customize watering schedules tailored to your unique landscape needs, while dramatically conserving water and improving lawn and plant health. The Simple To Set Sprinkler Timer offers maximum versatility and efficient watering with water-conscious features like Automatic Rain Shut-off to stop operation during rain. It can even be easily linked to existing drip watering systems. Just dial each zone and see every setting clearly displayed Because you set this timer by zones, you control the irrigation system exactly the way it is laid out. With this advanced timer, watering schedules can be fine-tuned for each lawn area as well as the flow rates of each sprinkler type. Zone-by-zone setting convenience. Because you set each watering zone independently, it's easy to schedule watering perfectly for each area: grass, shrubs, trees and flower beds. Features and benefits: All-in-one view. All displayed in plain language as you turn the dial to each zone. Loaded with user-friendly features to manage any residential or light commercial irrigation system. Rain delay command suspends watering manually, resets automatically on next cycle. One-touch seasonal adjustments to increase water in hot, dry months and reduce it in rainy seasons. Built-in trouble shooting of valves and wiring. If a short is detected, the timer suspends watering to that zone and displays a warning message. Superior surge protection guards against damage from nearby lightning strikes and power surges. Sealed from the environment to protect against moisture, insects, dust and grime. No need to reprogram after a power outage. All timer settings are stored indefinitely in memory. No backup battery needed! Simple wiring connections color-coded terminals with separately marked positions for master valves and pump start relays.

Multiple Common Wire Connections
This unit can accommodate two common wires (see photo) so you can consolidate two separate systems into one (for example, one system for the back yard and one for the front).
Water One and Water All
There seems to be some confusion about this as a number of older reviews state that you cannot water a single station easily or water all stations. This feature has been added to the unit (see photograph). For water all, you just hit the Water All Now button. For watering a single station manually, you dial the station and then hit the Water One Zone Now button.
Display next watering time
When the unit is set to Auto, it will not only display the current time, but it displays the date and time of the next zone to be watered (see photo) - a nice touch.
Watering a zone multiple times per day
It is true that you cannot directly control the additional watering times when you set a zone to water more than once a day. If you need this function, you will need to look elsewhere. For areas where it is not important to you exactly what time the second, third, or fourth watering per day is, the interface is pretty clear on when the zone will be watered (see photo).
The overall interface is very clear and easy to use. When programming a zone, you dial the zone you want, press the days that you want to water and set the time you want the zone to be watered. It all shows up very clearly, so there is no guessing if you set it correctly (see photo)
As a previous owner of a Rain Bird 4-zone system very similar to this, I decided to stick with Rain Bird and get this unit for the new house, which had a total of 8 zones.
The unit is completely silent and about 1/4 the size of the old one.
Installation was incredibly simple and straightforward. Most of the time you simply hook the wires up in the same order you took the old ones off. I recommend taking a picture or two of your current wiring before doing anything. This will allow you to reference back to what color wire controlled what zone and at least put everything back the way it way should you find yourself over your head.
Programming is also very simple. It also is pretty fool proof... for example, if you leave the start time for every zone at 8am, with each zone set to run for 5 minutes, then it will automatically start Zone 1 at 8am for 5 minutes, then Zone 2 for 5, then Zone 3, etc. This way, you can easily change the duration for each zone without having to ensure the start times for each zone do not overlap. It makes scheduling and updating very easy!
* Display next watering time: For some reason, it just says one zone instead of the all the zones we set up. It seems to water all of them but not sure it just says, zone 6, for example.
* No way to hold zone information/reminder card - in our old unit, the housing box actually was in a "box" so we were able to close it. Sometimes I just want to water our flower beds for a few minutes and forget which zone it is. Having somewhere to store that would've been helpful.
Other than that, so far a great unit!
Programming is the easiest of any controller I've ever seen. A 3rd grader could do it.
I was impressed.
