Thanks alot for the reply guys

Limited access

I don't. I will have to be in front of the panel. It might show it in the MTIII manual.

There is a setting in the OA setup. If the building pressure goes to low (under set point) the OA will go full open to bring the pressure back up

We have ALC in several of our buildings we service. The local rep is basically worthless. They won't even answer their phone or call us back. They are no support at all. Does anyone know where I can...

I’ll take it if you don’t want it.

…..

Those 300’s are nice

They do have the usb key and really only need the sewer ice tool. Thanks a lot for the information

I have already. The customer doesn’t have the money to do it.

The customer had a laptop with it on it . It crashed . Their new laptop needs reloaded with it.

I actually have a KTM now. I don’t race much. Every now and then

Does anyone know where I can get a copy of Carrier’s Comfortview? I looked on EBay , Amazon etc. I can’t find it anywhere. Thanks

Make sure you have one transducer controlling both drives in one common supply. Make sure both drives are set-up the same. Just my 2c

There's a way to check that unit's diagnostics with your meter. The instructions are on the inside cover. It will atleast guide you a little better. You will know if its locking out on heat or cool.

You really should tie into the system with comfortview..Those pilots can be sensitive sometimes.

I would also put a condenser fan pressure control on the other fan. Your trapping liquid in the condenser.

use your ohm meter. Check each wire for resistance on each end.

When in doubt,google it. Found it.

Does anyone know what the level 4 default password is? We have a building that we do the mechanical and a separate contractor does their Andover system.
They do a very poor job. I need to calibrate...

Did you try Trane.com under software ungrades?

Keeping your supply air around 55 degrees might help. Don't reset it higher. I had that same problem awhile back. That fixed it. Your situation might be differant.

If that was me, I'd install timedelays on each compressor. I wouldn't open that can of worms. just my 2 cent

True. They normally temper the air so that doesn't happen. My point is; the MUA is to maintain positive pressure. They can add DX for summer time too. Theres lots of options to "MAU's" .

The main purpose of a MUA Unit is to keep positive pressure in a building. That's why its called "make up". It needs to replace the air that is being removed. Really isnt meant to be for human...

Ok thanks!

Just got new computer with windows 7. I Have Rover Comm4 7.1 and service pack 9 installed. When I go to open the comm 4 Service Tool a pop up box comes up and says "Failed to open Comm Port" The...

Thank you

I need one for a Model YCAZ88DB3-46PA Serial REFM313AAA

thanks :grin2:

Ebay.

Is it possible to be able to purchase this software? :whistle:

I had that problem once before. I had to replace the tuc board. The input on the board was bad.

I use to think dial-up was bad. Hughes Net is just as bad and costs more. Call them up and they have you do self checks on the equipment. Nothing is ever wrong. They like to blame your computer. I...

ok thanks.. will try that

That pretty much sums it up..

Does anyone else have this service? Is it really that slow? Almost like having dial-up sometimes. I had cable awhile back I liked it alot more. I was thinking maybe my internet was slow because of my...

thanks! I'll drink to that! haha

I stand back and look at it now and see some things I could have done better and neater but in the heat of battle, its a little differant.

No, its one inch pipe. Its even a 12 inch spread(center to center) up at the top where it ties into the secondary piping. Just like the book said to do.
I even kept it one inch going to the pump...

I kinda like the big ol' straw hat..

ok. thanks

My plan was to get a small hot water heater. Set it at 100 degrees. The tankless is set at 115. When the tankless is running, its feeding the little heater with 115. When idle, the water temp will be...

Thanks. I did debate that for the longest time. I was looking at gas savings. If I did it again, I would probably go with the indirect. I'm not too impressed with the tankless. I'm going to add a...

sorry, I don't understand this.

Thanks. All the radiant tubing and headers are made by Watts Radiant. For my application, I could have used two port headers with two 600 foot rolls.
I wasn't aware of that till after I bought...

Thanks!

it needs to be programmed to see the sensor. If you have the sensor wired to the unit.

I was kinda thinking the same.

you probably want to put this in the control section.

here's their site http://aamatrix.com/



or try ebay good luck
