The ATH1 features an electronic LCD display with touch screen controls for easy ooperation. Precisely maintains set temperature using Automatic Climate Control. Sturdy base, remote control, 2 speed settings, and advanced safety features. Can operate in fan only setting for year round use. 5 year warranty.
