Yes it makes sense. I was hoping to just use the Jandy controller via the existing filter pump relay or its driver to start the main slower filter cycle based on the Jandy real time clock I can set in the house. Then when the solar relay 24VDC comes on, I kick it into the next step and it speeds...

My pump output will show both flow rates since its flow is optionally routed via the solar loop based on the Jandy solar JVC. So I'll install the flow meter on the pipe stretch I have to move that already has the water temperature sensor in it. Then I can check the rate of flow through the...

Got it. My thinking was if I need to raise the pump output pipe so the Vgreen control box has room, I would just put the flow meter in that new pipe stretch. That's where my Jandy pool temperature probe is located. That way I can monitor flow in both JVAC solar and no solar positions. I...

I'm so convinced, I just ordered it with a seal kit. thanks again...

My pump is a Pentair Sta-Rite P6EA6F-206L Max-E-Pro Energy Efficient Single Speed Up Rated Pool and Spa Pump, 1-1/2-Horsepower Pumps, 16/8-full load amperes, 115/230-Volt, 1.10-SF, 1.65-SFHP. Measures 30-1/2-inch length by 17-inch height by 13-1/4-inch width. It appears the ECM16SQU has the...

Got it. Looks pretty good. seems pretty straightforward. It even says its compatible with my Sta-Rite Max E Pro so I presume its just unbolting the Sta-Rite motor, bolting on the V Green, hooking up permanent 240VAC, building my Jandy output to Vgreen circuit for the solar JVA signal, determine...

Thanks! That sounds promising. I'll investigate. I should have no difficulty providing whatever signal it needs and derive it from the "solar pump" control 24VAC output that's not used. I believe this corresponds to the JVA on solar. The Sta_Rite pump itself is in good shape as it was replaced...

I have 3 Tesla Powerwalls 2s and will program them to charge during the day and discharge during the evening peak. I believe this does provide some advantage but I'll investigate. I bought the Powerwalls so I could power my house during the PG&E fire danger outages but they also provide time...

My Jandy Aqualink RS is programmed in the Spring through fall to switch the JVA when there is adequate heat available at the panels by measurement by the pool temperature sensor and solar panel rooftop sensor. As the seasons move through April to October, there are foggy mornings and evenings...

It says "Customizable for all situations" but how would the pump know when the solar JVA is routing water via the panels? My thinking was to install a flow meter inline with my panels and based on panel sizes and number of panels, try and determine where the heat transfer curve flattens out at...

Well its not totally moot since my existing system works just fine and I have 15KW of solar so I don't actually pay for the electric since the solar has paid itself off years ago. I actually get about $1000 back from PG&E each year. But I prefer not to waste power so was looking into upgrading...

I looked over the Github documents ( thanks) and at first glance it appears one must take over the whole control panel function and it doesn't appear possible to just interject a change flow rate message or return to internal operation. What I was hoping was there was some way using the RS485...

Its the second box at the pool with all the relays etc... One was not enough for all the "stuff" controlled.

Can the Jandy RS16 panel be upgraded from an old 5/2000 (7201 Rev I) to a newer one without changing the pool control boxes? Or are they somehow tied together? Can a new Aqualink RS talk with my 2 control boards ( main and remote) at the pool?

Somehow some text was overwritten by the 2 photos I attached. I am able to create my own RS485 signal of any rate and format. If any good VS pumps would allow my add on Arduino RS485 controller I would design to talk to the pump, I could in theory, tell it to go to a higher flow rate when my...

Thanks, My Aqualink RS16 diagnostics shows a 7201 Rev I. It appears from the Jandy revisions chart that this is a 5/2000 revision so obviously does not support anything but a 2 speed pump. So my options seem to upgrade to a new system or figure out how to arrange things another way. Option 1...

I have a 20,000 gallon inground pool with a large rooftop solar run by a Jandy Aqualink RS16 system and am investigating upgrading my pool pump from single speed to variable speed. But my understanding is lowering the flow rate by lowering the speed to save power also reduces the solar...

I have a 20,000 gallon pool run on a fixed rate pump and an old Jandy Aqualink RS16, 2" PVC pipe, with a propane heater, Spa, Triple cartridge filter and a large rooftop solar about 20 ft above the pump. I want to change out the pump for a variable speed pump but it seems I must know a few...
