You're better off without the fuckin' thing; the way they made that lil' bastard, the card is right in your way anytime you want to change the handle, and you have to hold your hand in an awkward position to change the temp unless it's up on the shelf.
If I'd been arsed to hack the stupid thing on mine, I might have discovered whatever fault it had BEFORE it died in a blazing fireball of toxic smoke.
BTW, welcome to semi-civilized soldering iron country; let me know when you get tired of the mentally-defective firmware on that thing and want to convert to a nice user-friendly OLED T12 controller.
