Separate Spa & Pool Light on Jandy System

[xeonman13]

Hi All,
MY pool builder installed my Jandy Pool System last year.
Part of that was 3 Jandy Watercolor Nichless lights. 1 in the spa and 2 in the pool. They are all controlled by the same aux port.
I want the ability to set my SPA light and POOL lights to a different color.
The pool builder told me i need another relay, which is fine and I can install that.
And I also understand how to change it in the app.
The part that confuses me is do i need a separate 12V transformer?

There is also an intermatic black box, not sure what that does. Pics of both attached.

Yes, you need a Intermatic PX100 transformer for every independently controlled light group.

The black box is your pool light junction box.

13,

For each light or group of lights that you want to independently control, you need a separate relay and a separate transformer.

Thanks,
