Product Description
The Battery WEM is designed for use with battery powered DC controllers that have a sensor circuit, functioning similarly to our standard WEM used with AC controllers.
Whenever a controller powers a valve, the WEM will either allow or prevent the irrigation based on soil moisture conditions. If the soil moisture is wetter than the setting selected on the WEM dial, an irrigation will be prevented. If the soil moisture is drier than the setting, the irrigation will be allowed.
Depending on the controller being used, either a closed or open switch position will be required to allow irrigation. The Battery WEM can be wired to accommodate either controller requirement, by selecting the appropriate switch connection wire pair.
Shown to the right are a Battery WEM with two Watermark sensors, as well as a wired installation of a Battery WEM on a DC controller.
