ET Manager™ Cartridge

Outsmart Mother Nature.

The Rain Bird® ET Manager™ Cartridge easily upgrades the ESP-LXD Controller or ESP-LXME Decoder Controller to an ET/Weather-based irrigation smart controller. The ET Manager Cartridge uses the same Weather Reach™ signal as the Rain Bird® ET Manager (ETMi).

The ET Manager Cartridge saves water by making real-time adjustments to the irrigation schedule based on hourly weather information. Additionally, by eliminating the need to travel to controller sites to make adjustments or programming changes, the ET Manager Cartridge contributes to significant labor savings.

The ET Manager Cartridge is ideal for high-end residential and light commercial applications. The ET Manager Cartridge is easily installed in any ESP-LX Series controller with minimal need for tools or wiring.

Water Saving Benefits

  • Wind interrupt prevents overspray during high-wind conditions.
  • Four separate moisture balances are maintained. One for each program or hydrozone to efficiently water varied plant types (example: turf, shrubs, trees, annuals, etc).

Easy Installation

  • ET Manager Cartridge easily mounts in any ESP-LX controller.
  • Antenna mounts on controller or remotely (remote antenna kit required).
  • Setup Wizard walks user through all key setup parameters.

Reduced Liability

Sensors and Accessories

  • ET Manager Cartridge incorporates a rain gauge input, for optional local rainfall measurement. Rain Bird offers the ETM-RG tipping bucket rain gauge as an accessory to the ET Manager Cartridge. The tipping rain gauge is an ideal complement to the ET Manager Cartridge, this electronic gauge accurately measures rain to 1mm per tip, reducing run-off from over-watering and avoiding landscape damage. The rain gauge is durable, weatherproof, and resists UV and extreme temperatures. Measurements per tip are accurate, with a maximum +/- 2% deviation. Each gauge includes a 30’ cable.
  • Rain Bird offers a remote mounting kit, ETMRMK, so that the antenna can be remotely mounted to improve signal reception or remotely locate the antenna to prevent vandalism. The kit contains a 30’ (9,1 m) cable, connector and junction box. The cable must be installed in conduit for outdoor applications.
