I've searched and read several threads but don't have a "definitive" answer. I also know that from reading this forum, there is a LOT of information needed to make a reasonable estimate on settings. However, I'm hoping someone here can provide some perspective on how I should have the furnace and HP lockout temps set on my system and perhaps provide some approximate ranges.
My issue is this: I have a dual zone hybrid Carrier system which has a HP lockout temperature and a furnace lockout temperature. Currently, my builder/installer has them both set to NONE, which means either can run at any temperature. Is this the right way for it to be set? Until today, I have not seen the furnace ever turn on and I hear the HP outside running all the time. My energy bill so far is much less vs. my neighbors so I think it's working, but based on what people say at this forum, it sounds like I should have these set to something other than none?
My other concern is if the HP runs ALL year round, how long will this thing last? Am I just "burning it out" by running it at temps lower than 20F, meaning it's not providing much heat so why bother running it constantly?
-I have a dual zone system (one upstairs, one in basement) with a Comfort series HP (two of them) and an Infinity gas furnace (two of them).
-House is approx 6000 sq. ft.
-Live in Cincinnati, OH
Any advice would be appreciated!
