Helo;
I just came across a discussion on this board, mentioning the A-1, and if I understood what I read correctly, seemed to be an interesting alternative to get better performance from my existing furnace, instead of going the very expensive route of replacing it altogether.

I wanted to post my questions right there, but could not, as the discussion seemed to be closed. This is the link where I read about it:

https://www.askmehelpdesk.com/heating-air-conditioning/aircycler-fr-compatibility-air-handler-239195.html

So, hopefully this will do... Here are my questions:
- Is that device usable with single stage furnaces (air handlers)?
- if the answer to the first question is yes, what is the cost of that device?
- further, I checked the manufacturer's site and it doesn't appear to sell it directly? Is there a place selling it on the Internet?

Thank you,
Hg

1. Yes
2,3 I found various models on the website and prices. $100+. Generally it's used in conjunction with a thermostat. There was a model that combined it with a stat. I think, but not sure, some of the Honeywell Vision Pro 800 models have this capability, just not as extensive.

The only thing that will cause you a little grief is if your thermostat lacks a common terminal (C) or a free wire that can be used. Common has been a recent addition due to the fact of needing to have a constant power source to some thermostats. Common exists at the furnace. It just may not be labeled.

The Tstat uses R or (Rc and Rh). This is connected to one side of the 24 VAC transformer. The other side of 24 volt secondary is the Common terminal.

Hello

Thanks so much for the quick follow-up.
I guess I have not checked carefully the manufacturer's site, since I have not found where I can order one of these devices. Can you send me the link?

Re: thermostat - I have an electronic, 5+2 programmable thermostat (could very well be Honeywell, I guess). Not sure where the grief may be... If only what you said, I will figure out the ground. No problem. I won't change the thermostat, if I can still use it.

Thanks again.

It's right in front of your nose. It's the SHOP link at the top of the page that you referenced.

The link is here: AirCycler Product Line (http://aircycler.stores.yahoo.net/)

There is hookup info as well on the website.

Sorry. I guess I wasn't clear enough, and we talk about two different things.

The link I've posted initially was about AirCycler, but later on in the same thread, a different device is brought up by one of the participants... :

"... One of the best ones we found was the A-1 unit which I have enclosed a bit of information on. [... ] This unit was tested at the university under all weather conditions in our weather chamber and so far has been the best to date for overall energy eficiency and comfort.I would like to add that Carrier Corporation(you know the biggest HVAC manufacturer in the country) has been using this device for 4 years on there fan coils systems with no complaints. I have three in my main home. One for each zone running back to the master computer that controls it all. Yep my home is not the usual cracker box to say the least. Variable speed CAC Constant Air Control is the only way to to. On and off time delays are really old fashion... etc."

Anyway thanks for taking the time to answer!

I posted that info and yes they are in business and still building the A-1 unit. They were tested by the university and also in my home.

I will post some info here.

Thanks very much for the extensive documentation. Can you also advise on how is this sold? I didn't find any on-line store carrying them.

They are usually sold to professionals. They are actually simple to hook up and come with full documentation..

You might try contacting them direct. (315) 858-1002

You might mention that customer I.D. (JCL) advised you of the A-1 quality and recommended there use to you.
I believe the retail is $450.00 but well worth it.

NOTE: If that is a bit expensive for you try the link below. It does the same basic thing but uses a different control system.
