Whats the difference? WeatherSense Rain Delay vs Rain Sensor

WeatherSense technology works with the Smart Watering program, which monitors the forecast and manual weather thresholds, to place the timer in an automatic weather delay when the forecast and weather thresholds are met or exceeded.

The WeatherSense program will suspend watering when one of three weather delays are activated.  WeatherSense has thresholds relating to rain forecast, wind speed forecast, and possible freeze warning.  These thresholds are adjustable by the user and can be accessed in the app on the device details screen.

The rain sensor feature on the timer works with a physical rain sensor that is placed on or near your home, which activates a rain delay when it senses moisture.  When the rain sensor detects moisture, the programs will be automatically suspended until the rain sensor dries, and allows the timer to be activated to run programs.  During an active rain sensor, the term RAIN SENS will be on the display of the timer, as well as, a rain sensor hold will be displayed on the phone application.

If a physical rain sensor is not being actively used with the timer, a jumper wire between the two sensor ports may be placed to close the sensor circuit.  If a jumper wire is not used, the timer will sense an open circuit and will place the timer in a rain delay.

In lieu of a jumper wire, the rain sensor can be turned off by pressing the RAIN DELAY button on the timer for 5 seconds until SENS OFF flashes on the display.  This will turn off the function to the rain sensor ports.  To activate the rain sensor on the timer, press the RAIN DELAY button on the timer for 5 seconds until SENS ON flashes on the display.
