1. Will that generally save oil? (I realize if I program it to 80 degrees 24 hours a day it won't, but in general, do people tend to save money because of the greater accuracy and flexibility?)
2. My oil furnace serviceman was against them -- he said they can mess up oil furnaces. I'm suspicious -- his company also sells me oil, so perhaps he's steering me away from greater oil efficiency?
3. As to brand - I heard good things about the Honeywell Chronotherm thermostats. Are they the one to buy?
