WR-7  Weather Reach Receiver

The WR-7 was our first smart control device, introduced over 10 years ago in 2002.  The WR-7 set a new standard for smart control.  From its foundation, many smart control products have been born; Rain Bird ET Manager, ET Manager Cartridge, Weather Reach WR-1 and now Controller Link.

WR-7 is still in use today and is popular with Toro Sentinel controllers because the WR-7 delivers hourly ET and rain to Sentinel controllers.  


A Weather Reach™ Receiver uses data from highly accurate, local weather stations to calculate the irrigation needs of your landscape. Weather Reach™ brings Evapotranspiration (ETo) based control to any standard irrigation controller to help maintain a healthier landscape while conserving water and saving money.

Four control methods makes the WR-7 a very versitle controller add-on device.

  • ET Enable Control - The irrigation requirement is equal to ET minus effective rainfall.  The Weather Reach Receiver maintains a moisture balance by accumulating the irrigation requirement.  The “common” output of a controller is interrupted until the moisture balance reaches a programmed threshold. Watering only occurs when soil moisture is depleted to an allowable level.  The controller is programmed to apply the amount of water needed to refill the soil reservoir.  Irrigation frequency is controlled based on ET.  Rainfall values measured by an on-site rain gauge or from the local weather station are used to calculate the irrigation requirement.  Irrigation is interrupted based on the amount of rainfall.  Excessive rain is ignored; the Weather Reach Receiver determines effective rain based on user settings.
  • ET-Pulse – The Weather Reach Receiver creates a switch contact for every 0.01” of ET for compatible ET-based irrigation controllers.
  • Rain-Pulse - The Weather Reach Receiver creates a switch contact for every 0.01” of rain measured at the weather station for compatible irrigation controllers.
  • ET- Trigger – When an ET threshold is reached; the Weather Reach Receiver creates a switch contact to signal a compatible irrigation controller that irrigation is needed.
  • RS-232 – ET and weather data can be directly accessed from the Weather Reach Receiver serial port by compatible irrigation controllers.
