I searched Goolge for "Pentair Relay 520106". See Link...

Here is a link that might be useful: Relay Part

I may be wrong but I think the control chip with the programming for the Easy4 and Easy8 are different. I don't think you can just add the relays.

Thanks, your googling worked a lot better than mine!

Hi Repiar Guy,

I discovered this as there is not any DC voltage to the pins 4-8 on the board when switches 4-8 are enabled, (pin sets 1-4 receive 26VDC when enabled). Since my board has these pins and my controller box has the places for the relays I can only assume that there is something in the software that shuts the extra pins off. Have you ever heard of an upgrade from the 4 relay system to the 8? Could this be done by a software upgrade or would I have to buy a complete new controller board?

Concretehole, you would need to purchase an EasyTouch 8 circuit board. repair guy is correct - AUX EXTRA is one of the better kept secrets about EasyTouch. It basically turns an ET4 into an ET5 and an ET8 into an ET9 (assuming you don't need Solar).

Just as a follow up to anyone going down this same path. I was able to get the extra relay, 520106, from www.americanbestpoolsupply.com with tax and shipping for $42.50. Some companies wanted as much as $80. It came with all the screws and the wire harness for connecting to the solar pins on the circuit board.

You can only add a single relay to the solar as the other 4-8 pin sets are not enabled. Also, I would recommend having a pro do this as one slip or crossed wire can fry a $400 circuit board or worse you.

Glad you got it concrete. We've seen a lot of toasted boards lately form guys trying to install IntelliFlo's and not knowing what they're doing. you've basically got 1/16th of an inch between the prongs on the board and as soon as they touch, BAM, new board.

Hi everyone.
First post here, I wanted to revive this tread to perhaps help us out. We have a new pool with a Pentair 8. I read that we have extra relays and wanted to know where there might be a diagram or instructions on how to connect up the extra relays? The isntruction manual really isnt clear. There are relays in the board with the small Low Volt wires connected and we wanted to run some lights up in the trees (120V) off the remote. We currently have them wired to a 15A GFI breaker we added in the panel. I assume we can just run the Hot (BL) in and out of the relay, then program it to the remote?
Any help VERY much appreciated, we've done quite a few exaustive searches to no avail as yet.
Thanks and cheers
Watts
