I would recommend the new Honeywell Vision Pro series, our company likes to promote only thermostats that offer the features you are looking for. The Vision pro I believe offers 3 versions 1) 1heat/1cool,3heat/2cool and 3heat/2cool with humidity control. They have battery back up feature that in most cases does not require a independent "common" terminal (you don't have to run new wires), they also have daylight savings feature that most programable stats do not feature. Best of all is the cool touch screen and easy programming. Our customers love them, we have installed aprx. 50 with no problems to date.
