Weather-based Watering – the Baseline Way
You can conserve water by operating your Baseline irrigation controller in a "smart" mode rather than in a timed mode. Unlike traditional irrigation controllers that operate on a timed schedule, a smart controller actively adjusts its watering schedule based on input from sensors. Smart controllers save water by applying the least amount of water possible to keep the soil moisture content in the root zone at the appropriate levels.
WeatherAccess™ applies real-time weather data from a weather station in your area (available in Weather Underground's weather station network), and configurable zone properties to a standardized evapotranspiration (ET) equation. This calculation estimates the loss of moisture from the root zone, and then the irrigation controller uses the calculated value to adjust the runtime in order to apply just enough water to replace that lost moisture.
When operated in conjunction with BaseManager™ Plus and WeatherAccess™, the BaseStation 1000™ and BaseStation 3200™ irrigation controllers meet the EPA WaterSense program's water-efficiency and performance criteria. The BaseStation irrigation controllers combine Baseline’s soil moisture sensor-based intelligent watering technology with the industry’s best practices for weather-based irrigation into a single user interface.
In WeatherAccess mode, Baseline irrigation controllers attempt to calculate the loss of moisture from the root zone and adjust the watering schedule accordingly. The controller's ability to accurately adjust runtimes depends on the quality of the weather data and how accurately the following properties are configured for each hydrozone in your landscape:
Having a good working knowledge of horticulture, water management, and an understanding of the science behind weather-based watering will help you be successful with WeatherAccess.
IMPORTANT! In order to connect to a weather station and access the configuration fields for weather-based watering, the BaseStation 1000 and BaseStation 3200 irrigation controller must be connected to Baseline's BaseManager central control platform, and you must have a BaseManager Plus account set up.
To get started, review the steps in the WeatherAccess User Manual.
