About the Rainbird ESP4ME

Save on the Rain Bird ESP4ME Outdoor 120V Irrigation Controller (F55110) with the irrigation experts here at PlumbersStock. This is a 4 to 22-station controller and it can be installed outdoors. As Rain Bird puts it, the features are so easy to use that you'll actually use them! This next generation controller is an upgrade over the ESP Modular.

As we've already indicated, easy programming is probably the most important feature with the ESP4ME. The single-controller keeps things simple. Delayed watering is a great option if you've had rain or if you're hosting a party and want dry grass. Conversely, if you have a Rain Sensor, you may not want it to trigger for certain areas of the yard. Say one station is found under cover of a deck or an eve, you can set that particular station to bypass Rain Sensor directives.

Other popular features include seasonal adjustment by program. Another is the Run Time Calculator which will allow you to track usage to comply with water restrictions or to ensure waterings are finished by a specific time. One-Touch Watering allows you to manually run your sprinklers with the quick touch of a button. There are two problem-prevention features: it can self-detect programming errors, and it also has Contractor Default where the original programs that are set up can be recovered if they are overwritten in error.

Because this is the outdoor version of the controller, it requires the electrical Pigtail (sold separately) for connecting to power supply. It's compatible with the Rain Bird LNK WiFi module (also sold separately). With a recent update to the mobile app, you can integrate your Wifi Module with Amazon Alexa for voice-activated control of your timer.
