Hi @vaqua55, good morning. Great question!
This is super simple to setup on the Iro. I'd recommend installing the pool valve to zone 1 or 16 on the wall mount. Then, when you go to setup your watering times, just make sure to exclude this zone from the list of zone options. You could even setup an on-demand watering time for just the pool valve that you could run at your leisure.
If you wanted to automate the valve in the future to turn on at set temperatures or trigger to activate pending a float valve, we have the ability to do so using third party software and/or hardware.
Hope this helps! Once you get the Iro installed, if you still need help, feel free to post here or email our support team [firstname.lastname@example.org].
