Hi,

Just picked up a nice Sundance shell (no guts) and am considering a Balboa VS510S pack. I was wondering if it is possible to have the topside controls on the tub along with a duplicate control panel in the house? They would not have to work simultaneously but one should be able to switch control from one to the other from either by the tub or in the house.

Thanks,
Stan

Most Balboa systems will allow you to run two panels. All you need is a 8-pin 2-1 splitter. Plug the splitter into the board and both panels into the splitter. They will mirror each other.

Try keep the cable short and keep it away from high power wires or it may cause issues.
