Timer 4 stations to 22 stations from Rain Bird

Rain Bird temporary more flexible in irrigation industry that supports flow monitoring, and the basic model can be expanded from 4 stations to 22 stations. You can use the same controller in home gardens as well as in smaller commercial applications. Once station units are added, you can expand your irrigation system without needing to remove or even turn off the controller. Expand ESP-ME3 to a smart controller by adding LNK wifi wlan unit (not listed) and WR2 rain sensor (not listed). The LNK unit simplifies programming and monitoring using the advanced Rain Bird app. With flow sensor installation, you can ensure improved water monitoring and increased protection against malfunction in your irrigation system. Wi-Fi connection users can access, operate, and monitor their irrigation system from anywhere simply by connecting Main Bird LNK WiFi Wlan (sold separately). Internet-based weather information is used for automatic daily adjustment of watering times, saving up to 30% of water. Flow monitoring compatible with various sizes and brands of wired flow sensors to monitor flow and adjust to save water and protect the facility from damage. Flexible installation can upgrade up to 22 stations individually and adapt using optional 3- or 6-station units. Powered by components and main housing for indoor or outdoor installation. Simplified rotary knob programming with large lines and symbols making it easy to understand the positions of the color-coded rotary knob. Easy-to-understand display with a large 3-inch screen that is easy to read even in dark garages or garden sheds. Rain sensor bypass for each station can override the rain sensor for stations under a canopy or in a greenhouse, even for watering. Seasonal adjustment for each program allows water saving by adjusting operating times seasonally between 5% and 200% without needing to change them individually. Alarm messages: the red LED light and text messages warn of system issues such as power, programming, and high flow (when using flow sensor). When using the LNK wifi wlan unit and Rain Bird app, these messages are also sent to your mobile phone. Touch-activated watering: when the rotary knob is in auto mode, the current irrigation program can be started simply by pressing and holding the right arrow key. Default Contractor™: the default program can be easily saved, and if the original irrigation schedule is accidentally overwritten, it can be easily restored in just two steps. Programming recommendations: Rain Bird recommends that the maximum cycle time for irrigation zones ends before drainage begins, and a proper soaking time is allowed before starting the next irrigation cycle for the same zone. Operating features: station run times: from minutes up to 6 hours; seasonal adjustment: 5% to 200%; maximum operating temperature: 65°C. Electrical features: required input voltage: 120V ±10%, 60Hz (international models: 230/240V ±10%, 50/60Hz); output: 25.5V 1A Master Valve / Pump Start Relay; operating voltage: 24V ±10%, 50/60Hz; maximum coil inrush current: 11 VA; maximum coil holding current: 5 VA; power consumption / power off: 0.06A at 120V. An uninterruptible power supply is required. The permanent memory permanently stores current programming, and a lithium battery (10-year lifespan) provides date and time settings for the controller in case of power outage.
