Success! The SmartJVA add-on board will allow Aqualink owners to be able to real-time set the amount their automated valves (JVAs) are open from 0-100% in 5% increments. It requires Rev R or newer. I am on version T.2.
Here is a link to where I got the SmartJVA board from. It was the best price I could find.
Jandy Smart JVA Assembly
Here are instructions for the SmartJVA board. They are not entirely correct.

I am now able to control my JVA's in 5% increments! Furthermore, I don't believe you need the OneTouch controller to get this working. The instructions from Jandy are not correct or more likely simply outdated.
The first picture below shows where the AUX ports are assigned to a JVA. On a running and working system, this is already working properly and does not need to be set/reset. This is what I thought I needed the OneTouch controller for but was incorrect. The OneTouch is not needed for this step. What the instructions do not tell you is that the aux port is ALREADY connected to an electrical relay. This relay connection is not necessary since the JVAs do not require a relay to work. You need to disconnect the relay connection if you have it (it is possible not all systems are wired with relays) (I just left it hanging) and connect the SmartJVA interface 2-wire connection into this relay slot. The SmartJVA comes with a pre-attached connector that fits the aux plug.
No splicing of any wires are necessary to get the SmartJVA board installed and working. It is entirely plug and play!
The second picture shows where the JVA is told it has a SmartJVA board attached to it. Since the aux port for the JVA you want to add SmartJVA functionality plugs directly into the SmartJVA board, when that JVA is activated, the board receives the signal from the aux port.
Once you attach the SmartJVA board to the JVA, it has a new menu when you access it, which is the third picture below. When you press it, it turns the JVA on to where it is preset to percentage-wise, but also gives you "decrease, increase, or save" options. Saving sets where it will default the next time you turn it on.
Everything you need to do is plug and play. You do need to open up your Aqualink panel to install the board. The power connector for the SmartJVA is just long enough to fit but I had no real issues with it. The entire process of adding the SmartJVA can be done in 15 minutes or so.
As an aside, the OneTouch controller is able to set the percent you want the JVA. However, when you turn on the device that is using the JVA in the OneTouch menu, unlike what happens with the computer or phone interface, you do not get an alternate menu to real-time select the percent you want. So if using just the OneTouch controller, you would have to go into the setup again to change the percent where you want it. I doubt I would ever use the OneTouch so this doesn't matter to me. But it is also not able to be set real-time with the PDA controller.
