The thermostat on the wall was very complicated, options were: Set, Hold, Run, Heat, Cool, Fan Auto, Fan On, arrow up, arrow down. I set it to Auto & set my desired temperature. The screen would display "Temporary." After a few hours, the temperature would change on its own. I was up and down all night readjusting the unit. I got 4 out of a potential 8 hours of sleep. Also the toggle for the bathroom sink stopper was broken. The sink never drained.
