I didn't have the time at work to look at this, plus it had already been sent out and we were told it was BER. Turns out you can get a TikTok person to fix it. The MD found him, I am too old to be a youth and too young to be creepy enough for it.

Does anyone know how to adjust the temp as it's a degree or so out at the moment?
