ET Manager™

A smarter way to water.

The IQ™ v2.0 Central Control Software with Advanced ET Feature Pack can utilize the Rain Bird® ET Manager™ as a weather source. The ET Manager receives hourly weather information and evapotranspiration (ET) from a nearby weather station. The ETMI ET Manager is located at the central computer connected by the ETMPS Programming Cable. IQ uses the hourly weather data from the ET Manager to adjust the satellite controller programming and station run time to maintain the optimum moisture balance in your soil. The results: significant water savings, deeper root systems and a healthier landscape.

Unsurpassed Accuracy

The ET Manager is the most accurate product of its kind, featuring hourly (not just daily) wireless updates from local precision weather stations. ET Manager technology is based on the Irrigation Association endorsed, ASCE*-standardized ET equation, and includes data from all required climatic variables (solar radiation, temperature, wind, and humidity). An optional onsite rain gauge can further localize the weather data accuracy. With the ET Manager, your irrigation system will always be in tune with the weather.

Healthier Landscapes

Increased watering schedule control means your irrigation system delivers water only when the landscape needs it. Best horticultural practices recommend deep, less-frequent watering. The IQ Advanced ET Feature Pack and ET Manager weather source do just that. Through a process known as “Managed Allowed Depletion,” they allow your soil’s moisture balance to reach a user-set moisture level that increases oxygen and promotes deeper, healthier root systems.

Easy Setup and Installation

Installing the unit is simple: mount it to the wall near your central control terminal and enter the simple site-specific information. A one-page step-by-step installation poster and quick user guide allow for quick, convenient installation and setup. In just minutes, ET Manager is ready to receive hourly weather data from the nearest local precision weather stations. Best of all, you get the benefit of comprehensive weather station data without having to install and maintain one onsite.

Cost-Effective Solution

ET Manager is a cost-effective weather source for the IQ Advanced ET Feature Pack. ET Manager requires a Weather Reach Signal delivered by multiple providers in the U.S. and Canada.
