Wasted a couple of hours yesterday and got very frustrated trying to get the gyre flow going and not because of the vortechs limitations to do this but because of programming issues. Here's the back of my tak and how the vt's are mounted:
That's an 8 foot tank and the 2 controllers at the top from outside to outside measures 6'9". The vt's are supposed to have a 10' operating distance and need to be in line of sight. I would think my setup conforms.
Without having to undo all the wires, the controller boxes are velcro mounted, I can get then to within 4'9" of each other to program, again, should be good enough.
I was having serious problems programming them. Followed the directions to the letter as I don't program them very often, I'm a set and forget guy. I kept getting issues with at least one of the controllers flashing an error message when setting the slave. and would have to start all over again. Must have spent an hour trying to program the pulse because of this, but finally got it to go with no errors. Don't ask me how, just lucky more than anything. Kept having to retry by setting different masters/slaves.
After getting it set properly, it just didn't look, sound right. Two of the pumps are a bit noisy and make a whirring sound. Also, two run hot while the other two are quite comfortable to the touch. The controllers being less than 7 feet apart should not have an issue communicating with each other but the ones furthest from the master weren't consistently getting the info packet from it, they weren't getting the packet more often than not.
After all that nonsense I tried to reprogram them back to my original settings with the same issues and frustrations. Wasted about an hour to finally get it back.
I think the only way to get a true gyre would be to have two electronic timers switching two pumps on and two pumps off on a half hourly basis, just not sure if the programming will hold once the power is cut when they come back on or wether it will do damage to the controllers.
Any votech users out there have any suggetsions as to getting a gyre flow without damaging the pumps?
