ZodiacR0466400 120-Volts Transformer Replacement for Select Zodiac AquaLink and AquaSwitch Pool and Spa Control Power Centers

I bought a used Blemished model for half off and then started reading reviews and got worried. But it came quickly and was spotless. I did test it using a line cord and a voltmeter and it worked. Slapped it into my enclosure and it worked fine. My fuse hadn't blown after rats chewed off a valve wire and shorted it out and thankfully my board wasn't fried and the display came back on my Aqualink RS system. Took me a while to figure out that this transformer was tucked in the back behind my Salt system controls and that the big transformer I was seeing on left was for the Salt. Pool repair company still hasn't returned my emergency call of a weeks ago.

I recently replaced this Zodiac/Aqualink R)466400 Transformer in my 120V control panel. For those of you having clock issues with your iAqualink 2.0 System, without a 9V battery, this may be your problem. This transformer is vital for your clock to run on time. As the transformer ages, the clock changes time. My old transformer was about 8 years old, causing my iAqualink 2.0 app clock to run slow. This started about 1 year ago when my clock was slow about 30mins to 60mins/day. Contacted Zodiac and they said the transformer in my 120V Aqualink RS control panel is going out. I figured I'd wait a little longer and change it out then. Recently my clock has been off by 2-3hours/day. So glad I changed my OLD Zodiac transformer out last week (pic 1). Simply plug and play with the new Zodiac transformer (pic 2). Now it's been right on time ever since! Nothing online about fixing this issue, just replace your 9V battery on the older controls. Hope this is helpful for iAqualink 2.0 or higher owners. :)

and priced under $90 when others are selling the same item on Amazon for over $200.00.

More than a few reviews on here have remarked about the same thing, a new product arriving, but that the voltages are either very low or non-existent.I had hoped that I would be a lucky one, but alas no.Thankfully I tested the transformer BEFORE I installed it and much to my dismay, the voltages were totally low and without reason: 2.04VAC and 6.39VAC (they should be 20VAC on both taps).I have returned for a replacement in hopes that the next one arrives in PROPER working condition and I will update my review then.UPDATE June 10 2020Replacement Transformer arrived and it was USED. Clearly has signs of prior use on the connecting wires and on the top of the transformer and, no surprise this one is ALSO DOA/NON FUNCTIONING.The seller/supplier MUST have better quality control.I am going to have to find another resource for this transformer.

The new unit I ordered worked. had before ordered from Amazon a used or open box unit for half the price, but the voltage was less than 24V AC. So returned the open box and ordered a new unit and that shows 24.9 V AC and works with the Jandy Auqualink RS board.However, it was no big deal to return the open box unit not working and teh new transformer while expensive works now like a charm. These transformers normally go very seldom bad. I had a power surge frying RS board and transformer.

No damage to box or unit but after installation the output voltage was only 13.84 VAC. The unit runs the control board but wished for the expensive price that it was the proper 24 VAC output as advertised and labeled.

Recieved ahead of schedule...Before installed i tested it (2 yellow wires)It had 26 volts as per the old one that took a dump(3 volts) also check fuse because when these blow up they tend to surge and pop the fuse.Installed and everything lit up...pool up and running again=)....good product

I like the fact that it was the exact match for my Aqua Rite Pool control panel.
