An air conditioner in our living room is suddenly, as of today, showing goofy numbers in the display that is supposed to be the temperature. I've unplugged it numerous times, no matter what, the display, rather than showing (say) 60-90 or so, is showing like 15-40. The "timer" light is not on (it has been before, but it's off now) so it's not that.

It does blow cold air, so far, but I'm concerned, another unit we had sometime back exhibited similar behavior & it wasn't long before you pretty much couldn't depend on it to function properly.

What could be causing this?

Did it somehow switch from fahrenheit to centigrade?

Good point^^^here is the Celsius (centigrade) number conversion:
20c = 68f
25c = 77f
30c = 86f
35c = 95f
You pr5obably should get a HVAC person out to check your system if it keeps acting up.

The batteries are only there to prevent you from losing your program in the event of a power outage. They have nothing to do with the thermostat's functionality, and even without batteries your thermostat will continue to work, except you will risk losing your program in the event of a power outage.

And what can happen inside if they're left in long enough for battery acid to leak?
