Taking a guess here. IN suffix is Inductive Load and without the IN the relay would be for a Resistive Load...

It can be powered either by 120v or 240v, but if I'm powering the relay from the pump relay, since I don't have a neutral on that I would need to power it 240v?

Is the acid feeder powered by 120 or 240?

Awesome thank you @JamesW !

Last question. Digikey is out of stock. On Amazon there is a G7L-2A-BUBJ-CB- AC24 (without the "IN" suffix). What does the "IN" indicate and would this be a suitable alternative?

Each JVA requires .75 amps at 24V AC

The coil amperage is 0.071 amps, which is 9.5% of the rated load.

Perfect! And adding that relay won't put too much load on that JVA port?

No, the relay is only 71 milliamps.

The relay coil will be powered when the actuator is moving the return valve to Pool Position.

Just measure if the voltage is Black and Red or Black and White when the Pool Return is open.

You can power the Relay Line In from the Pool Pump Relay Load out terminals to make sure that the Pump is on when the acid dosing is on.

The valve actuator sends 24 VAC to Black and Red or Black and White depending on the actuator position.

Power the relay coil in parallel to the Black and Red or Black and White depending on which is powered for the return actuator to point to the Pool Return.

• Black - Common
• Red - Switch Leg
• White - Switch Leg

The relay is the same as the other relays except it is 24 VAC instead of 24 VDC.

So for the actuator that controls the flow from pool/spa on the pressure side, would I splice in the relay to that same connection?

On a new pool, having each main drain plumbed separately back to the pad and being individually controlled by its own Jandy valve may not be code or VGB compliant.

Having each skimmer plumbed separately back to the pad is much better as you can adjust each skimmer separately to maximize skimming.

I'm thinking I could connect a relay to AUX 7 which I have the skimmer JVA assigned to it. When the skimmer is open, the AUX could be powered and then power the PH doser. Since the skimmer is open the major of the day (except when the cleaner is running) it would give it enough time to run. I would just have to make sure to turn the skimmer off when using the spa to shut down the doser. Not sure if I could automate that?

What is your pump daily runtime?

Thanks for the reply and I'll check the schedule in the morning. I fooled around with the schedule and set it up for flow rates since the heat pump is running and I'm trying to keep it at 93 degrees F. (until I get my first electric bill )

I was able to get the Paramount PV3 Floor Cleaning system up and running. (8 pop-ups and a water valve module.) Now I'm seeing lots of debris in the water. Seems like white scale and sand.

I'll be shopping for chemicals tomorrow.

I love this idea. Would simplify everything. Yes I have a suction cleaner which is automated by a JVA on Aux 1.

I do not have a relay attached to aux 1 but I have an extra relay I could attach.

My dip switch has cleaner OFF. Previously I had it on, but I discovered a bug years ago that Jandy failed to acknowledge was an issue. When the cleaner dip switch was on, I would randomly get an error in iAqualink when I wanted to turn on the spillover, saying the cleaner was running when it wasn't. (Or maybe it was the opposite, where the spillover was not on but the cleaner thout it was). I had since disabled the spillover dip switch and just have the JVA for that assigned to the AUX 3. It would happen once every couple weeks. It was not within the cool down period either and doing a "Cancel Delay" wouldn't help either. The only way to recover from this would be to reboot the entire panel. Additionally, the solar AUX is connected to a Jandy SMARTJVA that I want to be able to operate when the cleaner is running, so setting the dip switch to Cleaner would prevent this from getting power. Unfortunately I'm using all AUXs either through a JVA assignment or a relay.

I'll have to go back and review how I programmed everything and figure out if I can make adjustments.

Do you have a cleaner?

What is on AUX 1?

With an IC40 as the signature shows something is off. There's lots of FC power.

Power from Aux 1 and make it "Cleaner" by moving DIP Switch to ON.

That way, no power when water going to the Spa.
