Will do as soon as I get my war machine, and myself, out of the hands of the civil authorities.

Q: For the secondary winding of your HT01BC116 transformer what is the open circuit voltage and short circuit current?

Carrier's answer:

"
Your dealer is your best source for technical information. They have access to a network of factory service managers, who in turn have direct access to engineering. If you are not familiar with dealers in your area, a list can be obtained from our website.
"

What, Carrier doesn't have "access to engineering"?

Boo and Hiss.

If they spent their time answering all the questions that dealers should be answering. They would have to hire more people. And raise their prices.

Carrier doesn't make their own transformers. And doesn't care about open circuit voltage. And very little about short circuit current.

Transformers are picked by the OEM only to meet the equipment VA.

Amen

I'd rather they tell me that than having me chase wild geese.

They probably figured you really wanted to know. And if a local dealer wants to waste his time. He can.

Their answer is probably politer then you would get from GM, or Ford, if you called or emailed them about their ignition coils.

My answer was

I respectfully request you contact engineering about this matter and have them reply to this e-mail.

We'll see what happens. . .

Why are you wasting their time?

Why don't you call a transformer manufacturer.

They can refer me to whoever manufactures this transformer.
I'm not trying to steal their design secrets.
Let them give somebody else the runaround.

They aren't worried about you stealing their design secrets.

More like your just harassing them. For info that is not needed.

Its a waste of their time. Since they make no money off of you, by answering, or looking up, or referring you to a transformer company.

This is one of the things that causes us(tradesmen) to get a round around when we need to talk to them. They're afraid its another wasted call.

The reps that answer calls, and emails. Don't care about the transformers specs, other then voltage, and VA. Neither do the design engineers.

unless a court order accompanies your request, you might get a "we respectfully request you kiss out collective butts" or simply no answer at all.

They owe you nothing and unless they feel like wasting their time, you are not going to get an answer to your query.

Then the "Contact Us" button on their website should "Don't contact us unless you want to buy more of our stuff." It would save everyone time.

But, they want to maintain the "user friendly" illusion.
They hate DIYers. It's money out of their pocket when a DIYer fixes a $500 control board by replacing only a $10 relay.

Possibly less than half of the corporations I've contacted pass the buck like this.

I don't know how manufacturers view their relationship with tradesmen, but it's probably the same way a car manuf. views repair techs. A necessary evil?
If a repair tech has to call the Honda factory because of some design quirk, that can't be good. Honda probably says "How dare you?" in Japanese.

This attitude used to be called "uppity."

**beenthere** · 07-21-2010, 09:14 PM

The contact us. Is not for questions that are not related to the purchase, or a concern of install quality.

HVAC techs are considered both a necessary evil. And a sales tool.

The days of the friendly old Mayt*g repair guy are over. He never was real (an actor). The new stuff is 25% the quality and the actor is different. LOL.

You can't expect a huge corporation to care about a Popular Science project some geek is working on. Time is money and they allot it to money making calls. Try call Micros*ft and complain about their programming and see how far you get.
