This versatile control timer is the perfect accessory for your in-ground sprinkler system and will give you a sense of control over how much and how often you're watering your private or small commercial lawn. This particular unit is made to fit 4 base stations but if your grass is thirsty for more, expand the control timer all the way up to 22 with the help of 3 or 6 station modules. Settings on the front of the watering accessory make programming the timer simple, you're getting the most from your sprinkler with minimal effort. The 1-touch system lets you delay your watering for up to 14-days, which is particularly useful for when you and your family leave for a summer vacation or you have a work trip you simply can't miss. The controller also allows you to adjust the amount of water you're using depending on the season, the temperature outside and has advanced functions like syncing up the model with WIFI, giving you the ability to operate your sprinkler system and settings right from your cell phone or WIFI capable device. This smart device will also alert you of any potential program or electrical issues, so any power outages or unpredictable weather won't knock out the controller's memory or program settings you selected. If you're a meticulous planner, you'll love how specific you can be when selecting the day your lawn is watered and the frequency with which the sprinkler system operates. All the challenges of watering your lawn dissipate thanks to the manual, programmable features on this clever device.
