Explain Better. What do you need it to preset for? Are you needing a Timer or a Time keeping Clock with 24 hour readout? What is the application? Turn on sprinklers at 5pm and off at 6pm? What exactly do you need ? Does it need to keep time on a display? Or just a long time delay to turn on one thing. How many presets? Now I just confused myself. Hmmm I just need it as a timer. A clock with a 24 hour readout where you can preset the hour, minute and second. Thanks...
