Like I said..It might be just me,,,,.... Didn't mean that what I say goes as law.;-) Maybe I was in a weird mood. But,..I have a Mechanical pencil that is designed for drawing specs for only HVAC drawings. Coming soon will be the eraser that is totally something new.

I am sorry I was probably out of line;-)

    Forced Warm Air Fuel Economizers

    There are new fuel saving controls on the market for residential and commercial hot air heating.
    Visit Intellidyne at: www.intellidynellc.com/

    Go to "Products" and click on the Model FA (residential)
    and Model CFA (commercial)

    These units are for fuel oil, natural gas and propane ducted furnaces only.

    JP Yonelunas, Manager Technical Support, IntellidyneLLC

    The FA model is for furnaces up to 200,000 BTU input, while the CFA model is for commericial furnaces and packaged HVAC units over 200,000 BTU input.

    Team one of these up with one of the air conditioning models, (AC or CAC) and save your customer energy all year.

    Energy usage is reduced by a minimum of 10% which is guaranteed in writing, and come with a 15 year limited warranty.

    Sounds like a great Idea, But

    I gotta tell ya...I kind of hits me the wrong way that you out right plug your CO and it's products on a talk/help forum....Maybe it's me, but darn, put it in an ad and if it's good, It will get around.......We'd probably plug it for you if we like it.;-)

    Just a question where is the line in the sand between this and Burnhams posts. I would hate to see this become an advertising board but then again imformation is imformation.

    So...

    ... basically what we are looking at here is another form of the Beckett heat manager? If I take the literature you publish seriously, then much of the benefit of the -FA unit would be negated if homes did not feature forced-air systems that are 50-100% oversized. Sounds to me like an argument to right-size the heating equipment and/or modulation, not the retrofit of a box that makes the heating controller a little smarter.

    If I understand the description properly, the manager basically "learns" the response of the house to heat input, then adjusts the firing/fan running rate to compensate... Should be fun if the home features zone dampers and thus variable responses... or can your system detect/account for the presence of multiple zones?

    Retrofitting this sort of a controller into a intelligent HVAC system like a Carrier Infinity is sure to provoke some interesting battles between competing logics. I doubt that this control can communicate with the (presumably proprietary) 2-wire bus that carrier uses, or can it?

    So far, I see nothing that a modulating burner+logic can't do better. PID band-aids, are just that, band-aids. They might address the symptom and make the "ouchy" a bit less aggravating, but ultimately they do not address the actual cause of the problem.

    new products

    don't contractor tend to benefit the most from new products?
    easiers installs, better equipmenst makes for happier customers and more work?

    I would think new product bulletins would be welcome here?

    Applications

    Applications would indeed be limited to single stage on/off type equipment as far as I can see. We're starting to see the furnace manufacturers integrate some pretty scooby doo controls into their equipment, ala Carrier's Infinity setup, but by and large, the majority of units out there are still featuring prehistoric control devices. The ubiquitous T-87 Honeywell comes to mind. If people would only take the time to understand what some of the new technology can do for them.......

    That being said, there's a large market for such a device but I would rather see people invest in modern equipment. The return on investment is going to be better in the long run.

    Hmmm, "in the long run" now there's a phrase that seems to have disappeared from the American language.

    ... the long run depends on...

    ... the prices of the fuel choices a consumer has. Raise the price enough and all of a sudden many "long run choices" start to present themselves.

    One thing that I'd like to know is if there is anything to the rumor I've heard that the stack temps on low-fire by condensing furnaces are higher than at high-fire.

    All things being equal

    All things as in a good duct system with a clean filter, I've noticed very little difference in flue temps between high and low fire. Of course, the two stage units we install are Carrier and most of the time are set up with their aformentioned Infinity system control. This control will actually measure and display CFM and duct static pressure during setup so you know what you are dealing with going in.

    I was not trying to say you were out of line just a question in relativity. Apollogy accepted though not needed.
