Thermostatic Controls - VisionPro IAQ with new Trane Install

Hi,

I've been reading through many of the useful posts here in regards to the VisionPro IAQ setup and Trane systems. I didn't see my particular setup and was wondering if I could receive some insight into how I should configure my system.

This is the setup being installed. Still waiting for the furnace install to be competed, only have AC for now.

Trane XV95 Gas Furnace; TUH2B080A9V3VAB
Trane XR15 Air Conditioner; 4TTR5036E1000AA
Trane Coil; 4TXCB042BC3HCA

From what I've read, I believe the following should be wired:

EIM Furnace
---- --------
W W1
W2 W2
R R
G G
Y Y
B/C C
DHM2 BK

I should also:
1. Jumper on EIM R to DHM1
2. Cut jumper on air handler W14 (between R and BK)
3. Jumper on air handler Y to O
4. Set dip swich on air handler 5 & 6 to on for Comfort-R
5. Connect EIM DHM2 to air handler BK

I have four wires running from my air handler to the thermostat. I actually have two thermostats. One on my second floor controlling AC and the other on the first floor controlling the heat. I plan on just one thermostat on the first floor (VisionPro) to controlling both going forward. Not sure if this is ideal or not.

I also plan on buying a whole house humidifier which will be connected to HUM1 and HUM2.

If the above looks right then I have one other question. I'm at a total loss as to the VisionPro IAQ setup. Does anyone have recommendations on the settings for this?

My installer doesn't have experience setting up the VisionPro IAQ so I want to give him exact instructions on to hookup the system.

Thanks in advance for any assistance you maybe able to provide.

As long your got the air flow set right on the furnace you should be ok. How big is your home?

You have any returns upstairs?

What brand/style of humidifier are you getting?

Here is what I suggest. And if there's "E"/Auto Discover shown in set up, change it to a number value as I suggest below.

110 to 160 should be able to figure it out.
172-1
174-1
176-2
180-0
220-2
240-2
250-3
280-1
300- up to you.

340-0
342- have outdoor sensor?

370-1
372-3 (if you have outdoor sensor)
374-2
379-1
383-3
384-0

400-do you have fresh air damper or air exchanger?

Ask if you have any questions on the rest..

What are you doing for air filter?

Thanks for the quick reply Jay.

My house is about 2000 sq ft with a finished basement of about 600 sq ft.

Each room in the house and all the hallways have a return on every floor. The returns on the second floor are up high and the returns on the second floor are down low. I guess this is standard practice?

I plan to get the Honeywell HE265B1005 humidifier. I need a bypass model because I don't have enough clearence over the new air handler. It's replacing an older Aprilaire 760 which was ontop the hot air return of the old (shorter) system we had.

I have the outdoor sensor so I'll be sure to set this correctly.

I don't have an ERV as of yet. I'd love to get one but I just don't have the $$ at this point. Any suggestions on a good model that works well?

Ask if you have any questions on the rest..

I'm using a standard 1 inch filter at this time. I think the ultra allergine filtrete model from 3M.

Thanks

Did you mean the return on the main floor is low? What's in the basement? Also is it a living space down there? Age of the home?

I think both Honeywell's and Lifebreath are good brands.

Those are the worst filter to use, if you want good air filter, ask the dealer to put in a Honeywell media filter like F200 or F100, or Aprilarie's.

Did you mean the return on the main floor is low? What's in the basement? Also is it a living space down there? Age of the home?

On the main floor I have about 4 returns each one about one foot off the floor. i.e. one in the dining room, one in the living room, and two in the hallways.

The basement is finished wall to wall with carpeting except utility room with laundry, sump, furnace, etc. It's used as a TV room and game room for the kids. We have an electronic radon detector and also ran the manual lab tests prior to purchasing the home to ensure we didn't have an issue with radon. We spend maybe 4-5 hours a day in the basement.

The house is about 16 years old. Pretty well sealed all around, insulated and put down plywood flooring in the attic as well.

I should mention I'm a little concerned with negative air pressure in the house tough. I have two dual speed bathroom exhaust fans which run continuously and pull 30-80 CFM each into the attic exhaust and a range hood which can pull up to 750 CFM exhausting outside. I'm still trying to figue out the best way to ensure a balanced air pressure.

Thanks... I'll need to start looking at these systems.

Yeah, I'd really like to upgrade the filtering. The contrator is due back sometime in the next two weeks to complete the furnace install. I'll need to ask about the possibility of getting one of the systems you mentioned put in at the same time.

Thanks

Is there make up air pipe in the utility room?

Why is this fan on all times? Also, the exhaust from any exhaust fan should go out onto the roof, not in the attic.

If you got something this big, you should have a make up air unit installed.

Do it, cuz if you use the 3M stuff, you going to need to change the filters every month if you ran the fan 24/7 (I do any time the windows are closed expect in cooling mode)

There are no returns in the basement and only one vent. As a result, it's a bit more humid which is problematic. Have that musty basement smell. I suppose I'll need to get a room dehumidifier.

I was looking into the Panasonic passive Inlet Vent - FV-GKF32S1 to equalize air pressure. I'm just concerned it will suck in a lot of cold air into the room during winter. Any suggestion here? Could the inlet be piped into the return duct?

I put in a pair of Panasonic Whisper quiet fans in the bathrooms. They run on the lower CFM constantly then kick into the higher CFM when the motion sensor is triggered. I did this because we had some mold issues on the windows. My wife keeps the bathroom doors closed all the time (an asian thing) so it probably doen't help.

The bathroom fans are in the attic and I have them vent out under the soffits in the attic. This is how the old fans were setup, so I kept it the same way.

I just looked it up... price isn't too bad for the F200. Also looked at the F300 but concerned with some of the ozone reports. I might just go ahead and order the F200 so the contractor can install. I'm assuming I select the size closest to the current filer which is 16x24x1 which would be F200E1029 sized at 16x25.

Thanks

That can help, but I would add a return, and another vent in the family room and utility room, it will give you better comfort in the family room down there.

Looked at the vent, it is not enough. That only allows 15 cfm..... Here is something (http://www.homeenergy.org/archive/hem.dis.anl.gov/eehem/99/990113.html) you could read.

Have you thought about a timer on the fan, or don't think your wife will be good about setting the timer?

Media is the way to go, easy to take care of and filters are sold at Home Depot for Honeywell. Change filter every 6 months.

Is the furnace and return already installed? If not, go with the bigger one like 20x25, you will get a lot of filter area, and it will be easier on the blower.

Where are you out of?

That can help, but I would add a return, and another vent in the family room and utility room, it will give you better comfort in the family room down there.
I definitly agree there's not enough air circulation in the finished basement. I'll have to see if I can tap into the existing return... tought to tell where it is since the ceiling was drywalled. Would have been better if the previous owners put ina drop ceiling.

Thanks for the article. A very eye opening read... I'll have to stop into Home Deopt or Lowes and pickup a motion activated switch with timer to run the bathroom fan from. This way I can set it to stop after 20 minutes past the last motion activation.

Not sure what I'll do with the range hood fan yet. Since it has six speeds I suppose we could make sure we run it on a slower speed to reduce the effects.

I took your advice and ordered the Honeywell F200 media filter. Seems like a great way to get better filtration without constantly changing filters. I went with the 16x25 since my furnace is already in place and I don't have much room to play with.

Once I get the VisionPro AIQ installed I plan to have the fan run in circulation mode. Not sure if I'll run it 24x7 yet...

I'm sure I'll have many more questions to come. This is a great forum... your assistance / insight has been greatly appreciated!

Is the duct exposed in the utility room? You may be able to tap into that and run it to the wall between the utility room and family room.

Yeah, low is enough for most cooking, unless you guys do a lot of high temp cooking that leads to lot of smoke/grease into the air.

Run it in ON mode much as you can.. You'll get a much better comfort results with this, and get a full use of your air cleaner.

We have a split level home, and both upper and lower floors are +/-1˚ from one another with the fan on. The only time I don't run it is in the summer with the A/C.. It adds more humidity into the air when the A/C shuts off.

Has the dealer done a Manual-J (Load Calc.) on your home? My guts say it may be oversized.
