Immaculate unit. Looks good. Held not complicated, but nevertheless easily guidance (for people who grasp the operation is not intuitive). This switching between ON, AUTO, OFF and AUTO you just realize that you not define intervals at which power is required, but merely switching times to which one of the power on or off. Is the clock as a changeover ON or OFF, and not on AUTO, so is simply not connected, but it remains off or just to.
