I Have a 07 CalSpa Not sure what Balboa Pack it is.
But i Do belive it has the port on the board for a Aux Control.
What I Want to do is Get another topside panel that has the same options as the main unit IE- Temp and Readings
Is that possible to have two top side panels with temp controls.
If so im gonna wire the 2nd unit in to a cabinet in my kitchen so i can turn the heat up and down :-)
