Wow! I am thoroughly impressed with the quick response!

In a quick look online, I'm only seeing the RS remotes (744X part numbers). Do you happen to know of a source for the Ji series?

Hmmm...I had sent a message to Jandy service at the same time I posted my original question about the remotes and they responded that nothing has changed on the spa-side remotes so a new one should work.

Either way, I'm thinking that these things have to be pretty simple. There's six connections on the box. My guess is PWR, GND, and one for each of the four buttons and that pressing the button simply shorts the button wires to either PWR or GND. I just don't understand why that costs $150 at a minimum (I know, I know...it's because they can).

I'm wondering if I could just repair the existing or make my own
