Jimrahbe- Looks like we have the same equipment, Pentair VS pumps and EZtouch 4 system. I have a very big waterfall in yard with three large ponds, you can swim-in, operated by three Pentair VS pumps. I purchased the EZ Touch 4 system and hired an electrician to wire it up and they miss wired a fried the transformer, maybe the motherboard also? Do you know were I can purchase a new transformer, P/N521082? I found one never my home but they what $220.00. One other question: If the motherboard is bad I may want to replace it with EZ Touch 8? I need to be able to operate 3 pumps and pool lighting, I found that the 4 system may not do all the functions. Thanks.....Dan PS- My Waterfall ponds are also finish in "Tahoe Blue" Pebbletec!!!

hr,

The EasyTouch can only control two IntelliFlo pumps.. If you want to control all three of them, by using the data cable, you will need an IntelliTouch system.

If an electrician fried your transformer, why is he not replacing it???

Not sure you have the correct P/N for just the transformer. See this link Pentair 521233 Transformer for IntelliTouch Load Center

It may make more sense to control two of the pumps with the EasyTouch and one manually... basically just turn the pump on//off with a relay and let it run using its internal control panel.

Thanks,

Jim R.
 
Jim- Thanks for your reply. The electrician said it was a faulty transformer? I contacted Pentair Corporation and they sent someone out that represents there company from Greggs Pool Works. They check the wiring and said there was no need to attach YELLOW from transformer to breaker in box. Should have been wired 120. More than likely the motherboard was fried also. I took the part number of the transformer (521082) and Greggs Pool works had to cross reference the number to the right one. I hate the prices people ask for what I usually find for a lot less. My go to place is Polytec Pools in Las Vegas, not far from El Dorado Hills, Ca. The last two Pentair VS pumps were $879.00 ea., free shipping no tax. PS- I will be going after these people that put the blame on transformer. Thanks...So much for your help. I am glad I ran across your web site.
 
hr,

The transformer can be wired for either 220 or 120 volts... sounds to me like your installer wired it for 120, but connected it to 220.. He should buy you a new one..

Thanks,

Jim R.

Post a pic of the wiring and I can tell for sure, unless it has since been changed...
 
Hey Hotrocks,

Not sure how deep you want to dig into stuff but you can run the board alone with a 12vdc wall wart to see if it's dead (this is how Pentair's powers their intellitouch trainer systems). If you want to try it let me know and I'll whip up a picture or something on how to do it.

Jim- I contacted the people that installed the EZ Touch and they blame it on a faulty transformer??? They would get the unit up and running if I paid for a new transformer.Others I have talked to and saw the way it was wired and do nothing but install pool equipment, said the unit was wired wrong. I would post a picture if I could figure that out. Thanks again....All of you have been more than helpful!!!
 
Dan,

If you look at the top of the reply box you see an envelope... move to the right two place and there is an icon that looks like a box with a tree in it. You can use that to post a pic from your PC or device.

In over 50 years of working on electronic devices and systems, I could count the number of bad transformers I have seen on one hand, even if I had two or three fingers removed... :p

While your electrician is full of it, it may just make sense, money wise, to buy a new transformer and get your system up and running..

Thanks,

Jim R.
 
Hey Dan,
Here's a picture to tell you where to connect the 12VDC to test your board (and I'm assuming your transformer is disconnected from it). More details below...

EasyTouch power.jpg

It may sound strange to connect 12 volts DC to a 10 volt AC input - but the 10VAC input feeds directly into a bridge rectifier which converts it into DC anyway.

If you flip the board over and look at the back of the 10/18/24VAC input connector you'll see two bridge rectifiers (mine are marked DF1502S)... one converts the 10VAC to DC to power the controller/lcd and the other converts the 18VAC into DC to power the relays. The 24VAC input is not converted to DC and is used to power the valve actuators. The DF1502S rectifier is rated for 140Volts RMS input... so if your transformer was connected to 240VAC, then the board probably got 20-30VAC at the 10VAC input (unless one of the coils shorted), which should be well within spec.

Let us know if you have any questions,

Tom

One other question... is the transformer physically damaged or does it smell burned? It may still be fine... like Jim said, they're pretty hardy devices.

Here is mine wired for 120, the yellow is caped! Hope it helps

Felipe- That pretty much explains everything. The yellow wire was not capped, it was on a breaker. When I contacted Pentair they sent out a representative and he removed the yellow wire and capped it!!! You all have been unbelievably HELPFULL!!! Thanks so much.
 
Tom- I watched as the work was done on EZTouch wiring. All three wires from transformer were connected to breakers. When they turn on the power from MAIN electrical box smoke came off the transformer. Plus a few wires in the motherboard looked to have small bubbles on them. Thanks again for the help in this matter! Dan
 
oh nooo... the primaries on these transformers have a tap in the coil (this is why you can connect 120 or 240... emphasis on OR). if he connected all the primary wires to power he basically shorted the primary side, which would have made some heat and smoke. there's a chance it still works, but it should be tested before it's reconnected (you'd have to at least check the primary windings with an ohmmeter and test the primary coil with a much lower voltage)

if they're replacing this stuff for you then you should be all set. if they're not, i'm happy to troubleshoot further... which motherboard traces have bubbles? throw in a picture if you can.
 
Tom,

Once you let the smoke out, it is pretty hard to get it all back in... :p

I would replace the transformer, if for no other reason than future reliability...

How unqualified of an electrician do you have to be to get a license in the Sacramento area???

Thanks again for your help with this one.

Jim R.
 
Jim you are 100% right... a sketchy (at best) transformer is not something you want to try and save a buck with!
 
Tom,

I reread my post...

Oops... I did not realize that you were located anywhere near Sacramento... :uhh:

I was obviously not talking about you when I asked the question about the "unqualified" electrician... :p

Jim R.
 
Ha that's funny... I didn't realize Dan was down the road either!

No worries, I am not an electrician - but it's handy to know that maybe even I could pass for one in Sac! ;)
 
Dan emailed me a couple of photos of his setup, so here they are...

Dan, are the wires I circled in yellow the ones that bubbled, or were you talking about some damage on the actual board itself?

In the next photo you'll notice that the yellow transformer wire is now capped, it was at one point connected to a breaker.
