Based on this display, you would think the cooler would turn on because the current temp is greater than than the allowed range. No. It wont turn on until i lower the cool setting from 71 to 70. Based on that you might expect that it would turn off again when the temp dropped to 71. No again. It will stay on until it reaches 69. If i want the room temp at 71 i have to keep changing it from 72 to 70 every few minutes.
