I love this unit, it’s very quite and does a great job. My only complaint would be that when it’s in Eco mode, it shuts off and doesn’t sample the room temp.  It only comes back on when the temperature probe get warm enough.  This causes the room temp to spike.  So,I short, it forces you to put it in cool mode (stays running) and this defeats the eco mode savings. Oh well, it’s still a great unit.
