A very easy-to-use device that has not set the time. Irrigation timing to provide the duration of the programming time to a watering point. Example: Programmed is set at 16:15 clock, the time until the irrigation is over 4 hours. Then, each time watered at 20:15 clock. The watering frequency is relatively inflexible, when you want to repeatedly irrigate daily, then one inevitably to the "sunshine" (indoors is of course not critical). The device is functionally reliable and can (almost) be operated without operating instructions. For sophisticated irrigation methods or for professional use, the device is not suitable!
