Converting from Jandy RS4(PDA) to Circupool RJ-60 - advice needed.

[ladsjohn]

Hi,
My Jandy system is over 12 years old and has been temperamental in the past few years.
My latest problem mirrors what's described in this thread:

Jandy 1400 Power Transformer Burned...And?

where the molex connnector between the transformer and power board has melted. In the hopes of a quick fix; I replaced the power board but I'm still having issues. I believe the pins in the molex are the problem. I'm going to pursue fixing that for now (pigtails form the back of the PCB or a new/used transformer) but in the longer term, some on that thread suggested moving off Jandy altogether. I'd gladly do it .
If I were to move to the Circupool RJ-60 for Cl generation; can I continue to use my Jandy RS4 to control my Jandy VSP (which is still running strong)?
I'd imagine I just 'disable' the SWG on the PDA as if it never existed? If you've done something similar - would appreciate any advice.

I'm hoping to DIY it.

Thanks

Yes. Once you remove the RS-485 cables it should disconnect the Jandy SWCG.
You should however, put the power supply for the Circupool SWCG to the Filter Pump relay such that the relay will cut power to the SWCG when the pump is off.
If you have any questions, post photo of the relays on the RS-4 Aqualink box so we can see what is connected to what relay.

Great. Thanks. I've just been reading a few similar threads here so it looks like I'm not alone in this adventure.
So removing the RS-485 cables would be enough for the Aqualink to determine there's no longer a Jandy SWG attached? It's not going to generate errors because it's still enabled in some software menu hidden deep in the bowels of the PDA?

Thanks!

Correct - but I cannot guarantee that Jandy does not have some weird firmware.
I would remove the RS-485 cable and also remove the power cable if that is separate on your system.
Maybe show a picture of how it is set up now.
My SWCG transformer is in a separate cabinet from the main Aqualink cabinet so mine has both the power and RS-485 cables running between the two cabinets.
