Forget all that, you only set the power the tip is rated for, and the heater resistance.
This is not for the PSU, but to protect the tip, if you could run 200W into a T12 it would burn in seconds.
The FW does this automatically based on the PSU voltage reading, so it doesn't mater if you're feeeding 18, 24 or 30V, the applied power will be the same.
I doubt C210 can hadle 160W continuously (More like 70-80W) without burning or greatly reducing the heater lifespan, though JBC "kicks" it with high power for short time to compensate temperature drop and/or heat up faster.
But this behaviour will be probably be limited and controlled in the firmware to prevent overloading it.
C245 is a lot more powerful and shoudl take 160W without a blink, still no way it can take 280W continuously.
Using 12V might cause the mosfet to conduct poorly, overheat and burn.
Following this request, I made some changes to the button handling.

Feedback will be appreciated, but don't enter frenzy request mode, I really can't spend much time there.
Oh, so input voltage into the controller doesn't matter and the current is adjusted automatically. That's good to know.
I understand that I may have been over complicating things, but it's mainly because I'm trying to decide chassis size, and PSU specs. A part of me thinks that it might be better to start a DIY thread, but also a lot of this does relate to the firmware. In terms of what the options can be.
I'm exploring the possibility of using two irons at once from the same chassis. Keep in mind, similar to yourself, I don't solder that often but for specs, it might be nice to have for those rare times where I want two different tips for example. And having one enclosure and mains cable instead of two makes it easier. For example a heavy tip with higher power to solder a larger electrolytic cap, and a smaller iron with a smaller tip for fine PCB work.
Option A, a larger chassis than the standard size.. enough headroom in the PSU that it never reaches the limit (200W). Restricting power levels in the firmware doesn't matter much in this case.
Option B, the standard size chassis (maybe 160mm long instead of 130mm).. but with only 140W power capability. This should be enough power for C245 to work ok. Using C245 with a Pinecil/TS101 would not be an option. But T12 and C210 could work quite well in combination with external 24V port. The PSU has 3 X 24V outputs. For example, one for controller board, one for buck converter and one for rear output. But if the two combined are nearing the wattage of 140W, could I power limit T12 to 60W for example, or C210 to 40W if a situation required it? The way the irons draw current for a few seconds after wakeup, this is probably a non issue but I like to always have a little bit of extra headroom for long term reliability.
C245 140W
T12 80W
C210 60W
Those are the wattages I would like to use, but with the ability to set the T12 to 60W or 40W. And the C210 to 40W. Just wondering if this is possible. For example.. using T12 at 80W. Plug a second iron in the back for 5 mins.. set the T12 to 40W. Use the second iron for a few mins and then unplug it. Set the T12 back to 80W. I'm not really looking to request a bunch of firmware features, I understand that this is frustrating to have too many requests, but more to understand what it is already capable of. Also, sometimes simplicity is better than having a menu with 100 options. But this new feature does seem useful.
A vote here for ENC Wake, but it's a preference thing and all 3 are ok. There is only one button, so BTN Wake works. If I were in your position, I'd name it one thing and see how many people care. If it's the majority change it, if it's just one or two people.. leave it as is.
