Hi, I just got my new Circupool rj+ in last night and would like to install it myself. Could someone please check that I'm wiring this up correctly? I've attached a picture of my jandy aqualink with the cover off. I've shut off power and double checked with a multimeter. That relay in the top left with the two blue wires is for the filter pump. It looks like the black and white wires connected with them are going to the heater. Is this as easy as undoing those two screws and sticking in the black and white wires from the Circupool and running the ground to that block at the bottom? The jandy epump manual lists them as 230v and the Circupool says it's 220v.
My other question is what do I need to get the wire into the box without water getting in? I measured the knockout holes at around 7/8" and the wire at around 5/16".
Thanks so much for the help!
 
You will need to purchase one of those electrical conduit connectors that fits to those knockout holes. Knock out the tab, feed the wire through the connector and screw the connector in the hole.
Do you have a VS pump or a single speed pump?
When looking at the power relay, the 4 connections are Line 1, Load 1, Line 2, Load 2 from left to right
When you loosen the screw, there should be room to insert wire ends on each side of the screw under that tab. You want to ensure the wire is fully inserted with no strand sticking out.

If you have a VS pump - it is recommended to have the VS pump on constant power, you mention Jandy ePump so you can confirm that.
Line 1 will have 2 wires - the black main power and the blue VS pump
Load 1 will have 2 wires - the heater and the SWCG
Line 2 will have 2 wires - the black main power and the blue VS pump
Load 2 will have 2 wires - the heater and the SWCG

The pump will operate per your schedule on the iAquaLink program.
When it turns off, power will also be turned off at the relay (load side) to cut power to your Heater and your SWCG

Dont forget to connect the ground wires.
Also, switch off your circuit breaker to the whole system when wiring.

You may want to tidy up some of your wiring - lots of exposed wire that should be inserted properly behind each screw.

Edit - you need to also link your bond wire to your controller. CircuPool has a lug on the side. So get the proper sized wire and link it from either your pump or heater bond wire connection to the controller.

Edit - if you do have an Jandy ePump, you may want to review its manual. I remember reading that they may have a place to hook up a SWCG directly to the pump - where the wires attach to the pump motor. That may be easier for you. Not sure if that applies to all ePumps.
Edit - I looked at the manual for ePump and it was unclear if you could make the SWCG connection. It does have extra knock out tabs in the high voltage side of the pump electrical connection but no details on what can be connected to it.

I have a Pentair VS pump and how I indicated above is how I plan to hook up my SWCG in future.

Look for something like this, referred to as a "strain relief" cord connector/fitting. Find one that'll accommodate the width of your cord. I would install it in one of the bottom knockouts.

www.homedepot.com

Halex 1/2 in. ACC Non-Metallic Strain Relief Cord Connector 27693

The Halex 1/2 in. ACC Non-Metallic Strain Relief Cord Connector is intended for indoor and outdoor applications and is UL and CSA safety listed. This standard-fitting is made of plastic and is for use

Thanks! Got it. I do have a variable speed pump and I saw where it mentioned to connect it to constant power but I feel like it would be safer to only have the SWG on when the pump is on instead of relying on the flow switch. At least that's the advice I keep seeing anyway, to have an extra power disconnect in case the flow switch fails.
Thanks for the help!

I think you have a misunderstanding. The pump is connected to the LINE side of both connections. This provides constant power to the VS pump which is recommended. How the pump turns the HP relay on and off is done through the program of schedules.
The SWCG and heater are connected to the LOAD side of the HP relay. It only gets power if the schedule states to turn on the pump.
Then you have the flow switch as a secondary safety.

Definitely confused now! Those two blue wires on the load side are going to my pump. The two black wires on the line side are going underground somewhere. Does that mean it's wired incorrectly? It definitely works and follows the schedule

The 2 black wires are your main power to the pump. It is most likely coming from a breaker (is that nearby or in your garage? - it should be a subpanel for all pool equipment).
The 2 blue wires are for the pump per the original info you provided.
Right now you have the pump wired to LOAD 1 and LOAD 2. It works because when your schedule dictates "pump on", the relay activates and powers the pump and the RS 485 connection says - turn on pump to whatever speed you have set.

For power - you need 1 wire to Line 1 and the other wire to Line 2. This provides the power to that HP relay. If you throw the Circuit Breaker to off for the pump - no power will go to the Line side.

If you had a SINGLE SPEED pump, you have to have it wired to the LOAD 1 and LOAD 2 because it is basically an on/off switch. There is no control for speed, etc. If you put those wires on the Line side the pump would always be on because you removed the "switch".

VS pumps work differently -
For VS Pumps it is recommended to move those wires from LOAD 1 and LOAD 2 to Line 1 and Line 2. In this set up, the VS pump will have power but it will only turn on (or off) based on your schedule you have programed as it communicates through the RS 485 cable.

So with your heater and SWCG now on the LOAD 1 and LOAD 2 , when the schedule says "turn on", the HP relay activates and powers up the heater and SWCG. The SWCG will operate when the flow switch is activated. Also the schedule for the pump will turn on the pump. Your SWCG is only powered when the schedules says to turn on pump and flow is detected. When the schedules shuts down the pump, the HP relay is turned off, thus cutting power to the SWCG.

Okay got it! So I think I have it correct now, right? I also moved the wiring for the waterfall jandy vs epump below it as well. Thank you!
