Replace PCB for firmware 1.4?

[Felder747]

I'm looking to replace my dead salt cell on an aqua rite control board. The pool is only 8000 gallons, but I've got a Hayward t-15 hooked up to it with software version 1.4. After talking to an agent at Hayward they said I could only replace it with a t-15 because of how old the software is but that the t-15 would "probably last longer" because I wouldn't be demanding the full use of it. Can I replace the PCB to give myself software version 1.5 and allow me to use the generic replacements from pool supply world or even a t-5 or t-3? And is that worth it? What is more cost efficient in the long run?

I can't tell you about the software and PCB but the general rule of thumb for sizing is to go for a 2 x your gallonage or larger
This is so your cell isn't running flat out all the time and you have plenty in reserve. Your T15 could run at 20% most of the time making it last longer

Has anyone found a resolution for this issues? My firmware is 1.4 and I need to upgrade to 1.5 in order to use a generic salt cell. Do I really need to replace the pcb? Seem ridiculous for software update.
