Humidifiers and Dehumidifiers - Honeywell IAQ

I just read brochure on the IAQ stats. Seems like they have one complete model and then a smaller model that only handles humidity levels. Anyone have experience with these? I saw that the IAQ connects to the Honeywell UV air purifiers which is a very interesting concept to me.

Thanks for any insight...

I am the proud owner of the IAQ t-stat. It can do many things.


As for the UV light...???? Not sure what you saw??

On my IAQ it does these things.

Two stage heating
A/C
Humidity control for both heating and cooling
With cooling humidity control, it can slow down my varable speed blower to help remove humidity.
Outdoor sensor to control humidity level in the winter.
Control fresh air damper.
Reminder when to change Air filter, Humidifer Pad, and UV Light bulb.


The "smaller" model you are talking might be the VisonPro TH8321? if so, that one don't do as much as the IAQ does. The humidity control is only in A/C, and that does not slow down the blower speed.. Just over cools the home up to 3˚ below set point.

I envy that IAQ. When did they come out? When we moved into our new digs a year ago I was searching for a beefy tstat that could handle temp/humidity, etc. I was on the Honeywell website but didn't notice anything about the IAQ so I settled for a Ritetemp 8085c.

Hmmm... Just went to the Honeywell web site. I think I missed it cause they have the tstats divided into a DIY section and Pro-Installed models. I hate their website.


No, the smaller IAQ is called the TrueIAQ and handles all the IAQ functions except for temp ( I guess they want to market this to dummies like me that don't want to rip out a perfectly good Ritetemp 8085c but need the extra features). Here is the spec on it http://customer.honeywell.com/techlit/pdf/PackedLit/69-2072.pdf

As for the UV light.. seems Honeywell just revamped their line of UV air purifiers. The new models - like the UV100E are able to communicate over what they call Enviracom with the IAQ controller. This can allow the bulbs to be turned on only when the blower is running instead of constant use like the old model - saves energy and bulb life.

I envy that IAQ. When did they come out?About a year now.. I got it before it was advisertised I think it was anouced around March.

I would of shown it in the Pro section.

Oh ok, yeah that one a nice set up.

They are OK stat, I wouldn't keep it...

I'll have to read into it more tonight.. Mine just goes on a timer when ti's time to change bulb.

Figures... I was shopping in Feb :wall:

Did you install on the AC coil or in the return ?

Thanks

I was going both ways.... Figured if I put it on the return, I am kinda at risk of the UV light on the humidifer pad, and air filter... Felt the A-coil was best... So I have it above my A-Coil.

Yah, I figure I'll put it below the A coil since I got a reverse flow system.

Down flow system?

You have room for it between the floor and coil?

That's a good question. I'm not sure now. I'm gonna need help figuring this out.

The UV light instructions say it is best to install it where moisture collects so that it can kill mold growth. And logically they say that is over the A coil in an upflow system (since condensate gets blown up).

But since my system is downflow I figure it has to go under the "A". I opened up the air handler today and the only 2 places it'll fit is either in the middle of the "A" or else down below in the supply plenum. I think it'll do the most good up near the coil so I'm leaning toward that.

What do ya think?

Thanks

Not sure what you mean in the middle of the A coil??

Well the coil has the 2 finned plates that almost touch each other on top and then at the base are spread wide apart ( it's more like an upside-down "V" than an "A" I guess.) Well if you are looking from the side at both plates where you actually see the upside-down "V" there is room between the plates (more room as you move toward the bottom of course). And so since I have a downflow system the condensate is going to be sucked downward instead of blown upward. So I suppose it'll be wet under the coil instead of over the coil as in an upflow system. Thats why I was thinking of putting the light in the space between the 2 plates. Probably halfway up from the bottom of the coil. This way it could illuminate the bottom of both plates fully and also the blower underneath since I guess that area gets wet from the condensate as well.
