Well, I had a natural sea powerhead controller go bad on me. I guess thats what happens when it takes a bath in salt water while plugged in. Anyway, one night at work one of the line techs decided he needed to change out a lube spray timer. I told him it didn't need it. Of course he didn't want to listen to me ( yeah ok I have only been doing my job now for 12 years ) So, while he was gone I cleaned the mounting block up and he got back with the new timer and plugged it in.
He threw the old one in the trash can. Well, I knew it was good so I snatched it.
I brought it home and cleaned it up and did some research. I found a mode that would work. Then I built this.
This powerhead controller is programmable from .1 sec ( pointless ) to 9999 hours (way to long). I wired the switch output to a duplex outlet with the bridges disconnected. Works like a champ. Now I can program my modded powerheads to switch every 6 minutes.
The natural sea would only do 3 minutes.
Here are some pics.
Front of the timer
As you can see it has analog buttons to set the time and a digital display to show how long in the countdown cycle is left. The timer is an Omron H3CA
I used regular blue plastic outlet boxes to mount everything in.
I took 2 of the boxes and epoxied them together side to side slightly staggered. Then drilled a hole in the wall ajoining the 2. this way I could pass wires from the timer to the plug in.
It works very well. I told the line techs if they need to change anymore please save them for me. SO they will be saving them to test to see if any are good.
Hope you like it.
