I have a Jandy Aqualink controller with a Jandy SWG and a Hotspot pool heater that's setup like Solar in Aqualink. In order for the heating to kick on, I need to leave the pump running all the time. I'd like to idle it at the lowest possible speed - 600 rpm, and just let it kick up to a higher speed when heating. But at 600 rpm there's not enough water flow for the SWG, which requires 20 gpm (I presume for safety reasons). Is there a way to disable the SWG when the pump speed is low?
Turn off SWG when pump running on low speed

Thanks. My Jandy SWG does include a flow sensor but the manual includes a warning that it's meant to be used as a backup only and shouldn't be the sole source of flow detection.
It may be possible to have the SWG operate on a timed schedule. Don't know if you're powering it by means of a relay. If so, just time the on to coincide with higher run speeds.

Do you have an unused relay in your Aqualink?
If you do you can wire the power to your SWG through a relay and then program the times the SWG should be on to coincide with the pump higher speed times.

I do have a free relay. In my case the higher pump speed is whenever the solar heater is on. So with that idea, I'd want to be able to turn the SWG on whenever the solar heater is on.

The concern is when the SWG is running and the pump is off. Hydrogen gas can build up in the cell and explode. If the pump is running low and the flow switch fails to turn off the SWG, the water flow through the system should still prevent hydrogen buildup in the cell.
Thanks. From a quick look at my panel it seems like the SWG is hard wired into the filter pump's relay. I could probably hardwire it to a different relay for the solar, but then I'd be stuck without SWG in the winter when solar is off.
I'll probably suck it up and just run the pump at the minimum speed for the SWG 24/7. For my pool that's around 1100 rpm. Not too bad.
If that is the case, it is being controlled by the schedule that operates the filter-pump relay. I believe it energizes at the scheduled "on" time of the filter pump and de-energizes at the "off" time. The pump should not be wired through the relay, requiring power at all times, whether running or not. You would probably find that running the pump at 600 rpm would not actually be enough to get water to flow through the filter if it got a little dirty. I've never seen a system running less than 9-1100 rpm be able to move water very well. At our (SMUD) rates 1100 rpm, 24/7 would only cost a few pennies a day.

You could add a current sensing relay to your SWCG. It is adjustable based on the current. I think this could give you what you want. Some threads with the content.

Was pretty easy to implement, and I love mine. @laprjns likely, and I, are certainly happy to help if you go this route. Just set the current setting above your 600 rpm low setting and just below your high speed setting. Also want to make sure that the setting is at or above the flow switch for your SWCG. The setting on the CSR is such that you will likely be able to accomplish all 3 parameters.
I'm trying to decide if I can fit this into my Aqualink panel box or if I'll need a separate external box. Do you think the CSR would work if there are other hot wires nearby, so long as only the one hot wire in question actually goes through the current sensor hole?
