Trying to see if it's possible in iAqualink to set solar priority to turn on solar heat when air temp is higher than pool temp AND ALSO increase pool pump speed with solar heat is on.

Currently my schedule is set to 10am - 7pm to turn pump on, and is set to regular speed (2000rpm). I was trying to run the pump at 24/7 at a lower rpm but was struggling to get reliable flow on my Jandy Truclear SWG (I know it's not a great model but it's what I have and i'll use it until it fails). So currently just have it set for 9 hours during the day which seems to be enough. The issue I'm now trying to figure out it, I want to set Solar Heat to turn on when the temp is higher than the pool temp (as opposed to just scheduling specific hours to turn it on then off).

How can I set this in iAqualink? Also, is it possible to trigger a VSP Speed Adjustment based on if Solar Heat is enabled? If my Solar valve is open, 2000rpm isn't enough to send the water to the roof and still get good flow out of my returns, so I usually bump it up like 2700/2800 for Solar.
 
Show us your VSP Speed Setup page.

I think there is an entry for Solar on the newer Rev versions.

@MSchutzer @PoolGate may know.

If you have DIP switch 2 off (default) for Solar Heat, and you have a temperature sensor connected to the solar sensor terminals then you should have a Solar Heat function show up that you can enable and disable. When Solar heat is used it is hard coded to VSP speed 7. As Allen said, show us your VSP speed table. What does speed 7 say, it should be named Solar heat unless you have changed it, regardless the pump will go to speed step 7 if, 1- you have a temp sensor across the solar terminals, 2 - you have solar heat enabled, 3 - the pool is calling for heat, 4 - the solar temp sensor is at least 5 degrees above the pool temp, and lastly 5 - if speed step 7 is set to a faster speed then your regular 2000 rpm.

With the aqualink system the fastest active speed always takes presidency. If speed step 7 is set to less than 2000 rpm then nothing will happen when the solar activates as you are already going faster than speed step 7.

Please show us the VSP speed setting screen as Allen displayed so that we can figure out what is going on. For example here is that screen from my system.

Here you can see that speed 7 is setup for Solar Heat (the default name) and it's set to be faster than the default pool speed of 2100 RPM.
