It's been a long time, but if I remember correctly, these were part of a satellite system. If they have no day or hour wheel, they were given a start signal by the central. I vaguely recall that you might possibly be able to replicate this with a simple timer, like a Intermatic brand timer, but I am not sure where the start impulse needs to connect to. Hopefully someone with more info can chime in, or you might contact someone like Boardtronics for the info at [url]boardtronics.com[/url]
Good luck.
