ITC-308 alarm keeps going off

I bought an ITC-308 to operate a fan in my greenhouse. I set it up last year, no problem. This year, the alarm goes off all the time and drives my dogs crazy! Is there a way to shut it off completely? Or a way to program it so it very rarely goes off? I have another WIFI unit that lets me monitor the temperature and alerts me on my phone so I really don’t need an alarm on my Inkbird…

Please check if the reading of ITC-308 is correct?
Does it display the alarm code when the alarm goes off? For example AL/ or AH?
