I have spent some time today researching heat pumps and my Honeywell Vision Pro 8000. I live in Texas and this month's electric bill was shocking. I figure we have been keeping the temperature (72 degrees) too high with this heat pump. In my research I learned that heat pumps will go into aux or emergency heat if you raise the temperature more than two degrees. I am trying to determine if this thermostat is smart enough to know that, and thus save money by programming lower temperatures at night. I do have intelligent recovery set to on.
My research has provided mixed opinions on whether or not it is best to lower the temperature at night vs. one constant setting day and night. Can anyone tell me the most efficient way to run a heat pump with electric aux heat?
