Bear Toe Posted March 31, 2018 Report Share Posted March 31, 2018 Hi. I've got a 2012 Caldera Kauai. I had to remove the electrical service cable to install tub. I accidently removed the heater wires from the control box terminal block. Does anyone know where the correct positions are for the white and black heater wires?

Jersey Hot Tub Repair Posted April 6, 2018 Report Share Posted April 6, 2018 If it's got a Watkins control pack, the heater would be connected to the mini circuit board on the left side of the pack. If it's a 230VAC installation, Black generally goes to H1 and White to H2, however both lines are carrying 115VAC so it's doesn't matter which color is connected to which terminal.
