My new apartment has two wall unit ACs/heaters. The one in the living room is very simple: it has two knobs. One for fan speed, with three speeds each for heating and cooling. The other is a temp control like you'd find in a car, where you can turn it from "red" to "blue."
I've found that even at the lowest heat fan speed, with the temp cranked all the way to blue, it still gets way too hot in the apartment (I've seen it hit 75 deep in the room with my own thermometer before I cut it off).
I'm not really sure how this type of device works. Is it just blowing air at the selected temp continuously or is there possibly a hidden thermostat? If the former, is there any way to modulate the air temperature associated with a given temp setting, and if the latter, how can I access the thermostat? The bedroom one is a little different, and I feel like I've heard something switch off and on. Regardless, the bedroom one can keep it much more temperate. A
I wish I had brand info but I just thought of asking at work. I'm hoping someone sorta knows in general how they work...
