heat pump thermostat question

Posted by ONJ on December 3, 2007, 4:06 pm

I bought a house that has a newly installed Trane air heat pump and an
electric furnace emergency backup.

As far as I'm concerned I don't want the HVAC company that installed it to
look at it as they want to charge me for an incompetent setup.

The way its set up is the heat pump runs whenever the stat is calling for
heat...even down below temps in the teens and colder when the heat pump is
obviously useless...it still runs along with the electric furnace. This is
a horrible waste of electricity and I figure is costing me about 30% more on
my electric bill when the outside temp is that cold.

Anyone know of a thermostat that I can install that is inexpensive as
possible that will lock the heat pump out when the electric furnace kicks
on? Or one that I can install an outside sensor and the heat pump kicks off
at a certain temp and tells the backup to run?

Thanks

Wrong.

You figure wrong.

Ask your HVAC company.

Uh, it was the HVAC company that set it up this way....sorry man, heat pump
is no longer putting out heat, it is a waste of electricity. I know you
want to think that all hvac techs know what they are doing...but it just
aint so.

Yep. And they set it up correctly.

>...sorry man, heat pump
>is no longer putting out heat,

Yes it is. You don't know how to measure it properly to
understand it.

> it is a waste of electricity.

Nope.

        What you don't know is that I worked on heat pumps ( and lots
of other HVAC/R ) for 15 years, plus owning several, including one
now, and I know how they work, plus I hold 5 Statewide Masters
licenses in the trade, whereas you don't.

        Now, if you want to argue the point - go argue it somewhere
else, because NONE I repeat NONE of the techs here ( and most of the
regulars are ), with 10 - 20 - + years background each, agree with
you. Maybe you know more about heat pumps than all of us combined.
Good for you. Go ahead and argue against 200 + years of combined
experience here working on heat pumps, see how far it gets you.

        Then again, if you did, you wouldn't be asking your question,
would you ?

Wow...and you still don't have a clue about common sense.

Let me ask you something, do your customers know you think so lowly of them?

And you can still have licenses and be a hack.

LOL...the question was if anyone knew of the lowest cost thermostat that
would accomplish my task...not knowledge on heat pumps....what a moron.
