I have to do a recommissioning project on system that has JCI FXVMAs and other FX controllers.

Does anyone have the FX Compro BACnet VAV balancing template they can send me?

According to the...

The zero cut off is not the correct property to zero the transmitter. It's just a property to trick the display value as mentioned. It will actually make the box control even worse as in my case...

Can you explain what that variable specifically does. I saw that variable and it is set to some different values dependent on each particular unit.

I read that variable to be a calibration...

I have a building I was asked to review that has a bunch of Alerton VAV-SD controllers in it. From what I'm seeing basically every VAV in the different air handler systems have air flow sensor...

The controller I was using was a 517 but assume the 520 would be the same.

I have although it's been about 8 years.

That was pretty helpful.


The TU pc id is based upon hardware and MAC addresses. This being said one of your MAC addresses is probably changing. There are two instances I've come across...

I don't know what happened but can tell you that just because the computer has an IP address there would be no reason to change the connections to BACnet ip. As long as the network remained the same...

Supposed to be V17 and atleast SP9 to support windows 7.

You can auto save them as a text file instead of .rpt . You can open them on any machine in that format.

Take a look at the KMC Flex Stat. With our multiplier I think they are slightly cheaper than a Viconics and make the Viconics seem like a toy in comparison.

There is a time out feature in the boiler that is adjustable but can't be disabled. Adjust it up and set your modbus points tuning policy to rewrite faster than the time out interval

Are you sure the dampers are functional?
What is reported as far as damper position from the controller?

The answers to those two question might point out where you should look. I would look...

I thought it was the worst one yet and if it weren't for the fact that Niagara 4 is coming out prior to the next one this would have been my last. It seemed to me all they were doing is playing...

Is this a lochinvar? It sounds like a lochinvar intellifin and they have an integration guide for it. The controllers are and aren't Honeywell. They have their own secret sauce running on it. ...

Some one have them all set the same?

I suspect you are adding a regular folder and not a point folder,there is a difference.

The one with the little round icon would be a point folder. Without would be a regular folder. You can add...

Yes, you use the custom report generator and set it to pull data from the trends. You can then schedule it for up to three times a day and set it to deposit the files in a folder on the computer. ...

I haven't done tons of integration with the SC but I have pulled in both 3rd party devices on both BACnet IP and MSTP and it worked fine. I haven't done any third party Lon devices so I can't speak...

Well all I can say is I work in the automation field and my #1 and #2 stat choices were the ecobee and a radio thermostat ct80. Number 3 was a Honeywell with their wireless communication offering. ...

I haven't heard of any one doing modbus and doubt any one has worked on it with the Vera. I don't think there is the need. What device in a house would be modbus? I can't think of any home...

Ecobee also has another model stat that doesn't have touch screen. It will still do more than a nest but not as much as the other ecobee. Once you finish setting up you never really have to touch...

Yes

I would compare it to an Johnson NAE before a jace.


You do need Trane software to program it but most basic setup is done with just a browser. Trane software is only needed for custom graphics...

Just busted out my spread sheet, only have $1431 in it

I didn't buy a kit. I started with the controller and a door knob to control and monitor a dog walker we had to hire. I think I'm in it for about $1500-$1800 at the moment.

I don't know the function of your delay but suspect this would work out to be a delay on stop not an enforced min on/off time.

Why don't you rewrite your heating and cooling logic to call for a "FanRequest" for turning on the fan for unoccupied temperature control. The reason I say this is you are applying a deadband in...

I've never wrote Lua script before but the logic is easy enough to follow and I have programmed controllers with controller specific programing based on C++ and Basic.

Don't know if your problem is going to come back but you should think about upgrading that Jace to atleast 3.5.

They make a Lon card for a microtel voyager as well but it's only available with a certain firmware revision of the main control board so you may have to replace it as well for that route.

That equipment doesn't have an unoccupied mode. You have to do any unoccupied sequence in logic in your controller. That's the way it is with older voyagers.

I haven't dealt with it on a professional level but am currently taking courses on it at the local community college. It's been relatively straight forward to deal with.

Why wouldn't you just use a label with static text.

You didn't mention whether you meant a program object or a wire sheet program. Check your messages. There might be something there you like.

Do X and or Y have to be an adjustable variable or only the X(amount)?

When I was 16 I knew everything.

That feeling lasted until my early to mid 20s.

I'm now 38 and realize I don't know anything.

I was thinking that Valence was a brand. Either way the Peco stat will do auto change over and can be gotten without the fan switch with just up down stpt keys.

Peco makes a cheap stat capable of this. Viconics is another option but it a little fancier. The Peco is suited for this application if student because it has a no frills slide switch for fan speed...

You have to buy TU but there is a free BACnet setup tool from trane that allows you to set up the device. http://trane.com/Commercial/DesignAnalysis/DownloadCenter.aspx?i=909&p=18
