So, I was having problems with my pool equipment, and this technician took out my old jandy aqualink control board and installed a new one that he said was covered under warranty. But when I try to use it with my old PDA, the PDA controls all the functions except it doesn't have a control for programming. So now I can't program the pump and cleaner to run at certain hours with my PDA. I can only turn things on and off. He claims it is the replacement to my old one which he says went bad. Not true, but that's another long story.
Now he's offering me a iaqualink jbox and antenna and telling me I can just install that and just use my phone. I'm a little concerned about him making more of a mess of things. I can't figure out why my PDA is compatible and works with everything except for programming.
