I used mind for the first time this weekend, and I just set my temps and went with it, nothing too complicated. It could blink all day if it wanted to, as long as it holds my temperature (which it did).I just rcv’d my DigiQ3. I am not happy with the small 3 character display, it makes it difficult to program. Anyone else agree? Also, who counts the number of blinks to determine the blower speed? That is cheesy.
