Fair enough, the furnace isn't necessarily oversized for the house, just the duct system. That of course is if it doesn't have any of the other possible issues you mentioned.Originally Posted by RoBoTeq

Fair EnoughYou know it's one thing to want to learn the trade, and just humble yourself and sit back and watch and listen, but when your argument is not fact, and you don't just stop for a moment to research something before you post, you not going to appear to be the brightest bulb in the house. It's like me going on a TV repair forum and and telling all the pro's there how a TV works or is wired.

That would be DIY training which is not allowed.

Do you really think I'm doing these thermostats as some sort of DIY project?
Professional Member*
I never said anything about your installation of thermostats, just that you don't know what you are talking about when it comes to furnace operations. What is the model number of one of the furnaces that schematic you posted is from?

On a Lennox G8, which uses the honeywell/trade line fan&limit combo.
The primary side of the transformer is wire to the "limit" side of the fan switch, which opens of temp rise, but keeps blower running.
Therefore, when the limit setting is reached, the whole 24v control circuit is dead.... Gas valve and t-stat.
Many old furnaces use this configuration.

It's from a carrier.

The York D1NA048N09006C gas pack breaks power to the R terminal when the limit, aux. limit, or rollout opens.

I know what old furnaces use, but there aren't that many furnaces out there that are that old any longer. We are discussing current systems and why oversizing new furnaces is a problem.

I got that. Which Carrier model? This does not seem to be a very popular board.

We are discussing new residential furnaces. If we were discussing cars, we would not be concerned with having to deal with crank starters, now would we?

I have already mentioned it once, if you don't want the stat to cut out during an open limit on that particular board, wire it to the red on the secondary side of the transformer on the primary side of the limits, there is no danger since the gas valve is protected by a high limit, jeeeezzz! how simple!

Ok maybe a stupid question here, but why would anyone sell or even buy "today" a stat that is dependent on the system transformer to power it? that is really old school. I sell the Honeywell 5000....6000 and all of them use batteries, stat never goes blank, well unless the batteries run down.

Because old people and dumb people forget that there is batteries in the stat. Then I get no heat calls at 2am to change batteries.Ok maybe a stupid question here, but why would anyone sell or even buy "today" a stat that is dependent on the system transformer to power it? that is really old school.

You don't like making money from service calls or having reasons to go to your customer's homes for potential upsells?

Changing batteries on a 3 year old system because our installers failed to explain there were batteries, or the customer forgot at 2am is not a good opportunity for "up-selling".
I don't make commission and make plenty of money of legitimate repairs during regular time.
Man, you are an extraordinarily frustrating person.

Only if you let him be, he don't frustrate me at all, matter fact I wished I knew half of what he knows about this business, I could be setting on a beach in Tahiti, drinking margaritas with all the girls on the beach....ask Robin, I am like a chick magnet, and a pretty darn good dancer to, even at 61.
