Okay I misunderstood what this circuit did. I thought it would go back and forth over and over, 24/7, until I chose to turn it off.
What I need is for a paludarium (terrarium with half land, half water to simulate a riverbank, with plants, reptiles and fish). Its 6 feet tall, 5 feet wide. Plants need more intense light than flourescents can provide, so I'm using a HID lamp, and instead of having two lamps, one on each side, I'll use a light mover to convey the lamp back and forth on a track, all day long. I would like it to pause around 15 to 30 minutes on each end before going the other way, because the largest plants are on each side and they need to get the most intense light. Everything needs to be automatic. The lamp and mover will be on a timer so they come on at 8 am and go off at 10 pm.
I'm attaching a diagram of the quickest way that I thought would work, but I didn't realize the timer I had with two output plug-ins turn off and on at the same time, not independently of each other. So I figured that I would have to build a circuit from scratch, which brought me to you.
Apologies for the confusion.
Can we modify your circuit to be automatic?
I guess I could use 2 of the Brinks' timers instead, but I was worried they would eventually fall out of sequence with each other. The instructions says they may lose or gain up to 2 minutes a month.
