Take the hassle out of watering the garden. The innovative blue tooth timer works with the Melnor BT Apr to easily set watering schedules directly from your smart device. Choose up to twelve unique watering start times to match your specific lawn and garden needs. If rain is in the forecast, use the watering delay feature to pause the schedule for up to seven days. The regular schedule will resume once the delay is over. If you need to see when the next watering cycle is scheduled or when the current cycle will end, check the app to see what's going on or make a quick change. Switch over to manual mode through the app or directly at the valve to turn on the water whenever you need it.
