well I'm gone at least 10 hrs a day during the work week, i usually set it at 70 and forget it. the tech told me that the dial units aren't as sensitive to changes/ temp drop,rise, and cause your furnace to run longer than needed, but i would think being "too sensitive" would cause it to come "on" and "off" more often negating any savings? i don't want it coming on every 1 degree drop in temp,but, if it shuts off earlier it would be a benefit. sounds kinda like "spin" talk from the tech wanting to sell me more products
