because my husband turned on the air conditioner at some point before he left on monday at 5am. which is why cranking up the temp wasn't working. w.t.f. the low sunday night was 35. i may kill him. he always does irrational shit when he's hot.
let's forget that i forgot to check that until today. in my defense, on our thermostat the temp can be adjusted without opening the compartment thingie with all of the rest of the controls.
