I do not see the firmware file in the link. The file is called out in the one pdf that you linked.

I appreciate the files, but those are the NSTV 2.2 application with associated USB driver. I already have them.

Looking for the USB TO CCN converter firmware to upgrade an old converter. I have...

I have lost the USB to CCN converter firmware file 2.1 and can not find it on hvacpartners.

I have an old converter that I am getting a version error with NSTV 2.2. I think I just need to upgrade...

So another update. Power cycled the heat pump for 20 minutes. Upon restart the target evap was 43 degrees. I let it run for 1.5 hours at the target stayed at 43 degrees.

This is 1 degree off what...

Just a update....I called Bosch tech support today. It seems like for some reason the heat pump did not see my dip switch changes. The unit is operating exactly how it would with the default...

I appreciate the feedback and yes I cycled power after changing dip switch settings.

Let us forget about the zoning. I mentioned it, because it why I choose the Bosch. But at this point the dampers are installed and are sitting wide open.

I am not uses a thermometer. The Bosch...

Are you suggesting that I should close some dampers down and that will lower the target evap temperature of the Bosch Heat Pump?

Not following that theory at all.

Again, with dip switch 4-3 and...

I'm looking at parameter 11. "Tes target of the evaporating temp" is straight from the Bosch manual.

Again, just thought the target could be set for 37 degrees.

As far as the zoning, it is not...

So I finally got around to installing my 3ton Bosch BOVB Heat Pump with a Gas Furnace. I'm also almost done with a new zoning for the system.

Doing research, I know I need to turn off "Adaptive...

Yes it is!

Everything you stated can easily be fixed. What drives me nuts with Windows 11 is the right click on a file. All the good stuff is hidden and you have to go to "Show more options". You have no...

I never seen anything like this. The engineer should be shot.

We switched over to smtp2go.com for our small sites that do no provide a corporate email relays.

It's funny, I only have run across this with Trane. Their high end RTU's utilize Single Zone VAV operation. And they have their issues.

Trane utilizes minimum outside air damper setpoints base on...

Also, verify that the BACnet Space Temp BAS out of service is not True.

I have done many Supervisor both ways. I can tell you doing virtuals is way less labor, if you are doing the work from scratch. So new Jaces going up to a new Supervisor. You just need to get the...

What is ballz accurate? What did you compare it to? I know I have used my Fluke setup and it was within a degree of the commissioning agent's reading. Not sure if that is ballz accurate, but the goal...

I don't mean to hijack the thread, but what is a qualifier. What does it mean to qualify someone else and why is it necessary? It seems like a Florida thing. I have only been doing this for a few...

Maybe I'm too old, but I have been using a Fluke 52-II with 80PK-8 pipe probes for the last 17 years and they are dead accurate. I know I can throw both on one line and they are within a degree of...

Where guys struggle is relativizing the station names. If you are using virtuals it is easy. %componentSpace.rootComponent.stationName% will relativize the station name. What's nice is it will work...

Here is what I use in one of program blocks. This block you can choose between 3 different refrigerants.

/** Calculation shown below obtained by using CurveExpert. 99% accurate regression */

Understood, that was what I was looking at.....the constant torque ECM's. Any issue if for some reason the ECM received a high speed and a medium speed command at the same time? Any damage to the...

I appreciate the responses. I really do not want to bastardize any of the equipment I install. Trying to keep it simple, but achieve the desired results.

So currently I'm thinking the following:...

Not sure what you are asking.

Do you want to see at what priority level a BACnet point is being written at? Or are you asking how to write at different BACnet priority levels at the supervisor...

I'm planning the replacement of my furnace and air conditioning. I want to split the system up with 4 zones. Doing the heat load, the zones are weighted 40%/30%/20%. The forth zone is the...

I was able to guess the password, so I'm good to go. Able to access everything now.

Still would like to know, if there is a way to reset the user and password for the future.

I have a job with 3 TAC R2 UNC's that we are looking to replace. I would like to get into them to document any programming and Lon links. I do not have the host password. Looking at some copies of...

So klrodgers sent some code, which was extremely helpful. But it was not for 410a but 134a. It had instructions to use a Polynomial Regression to the order of 6 inside excel. It proofed to not be...

I have a job that I want to monitor the super heat and sub cooling on a 4 compressor DX cooling unit. I'm not controlling to the superheat and subcooling, just looking to monitor and trend the data....

So I'm a controls guy that just bought a new home and looking to replace the HVAC system.

I would like to utilize a single unitary setup with 3 zones. I preformed a heat load of the zones and...

I only have one customer with a Tekmar 369, but I will try to help.

First off the D070 Tekmar Brochure is just a troubleshooting guide for their 10k Type 2 sensors. That would include there...

Yes you would need Carrier NSTV and Ivu Tools(Field Assistant) to setup and configure router. But even if you went with the Jace CCN Driver, you would still need NSTV to service the controllers.

We do a lot of CCN to Niagara integrations. We have stopped using the Tridium driver. It's limited to only Status, Schedule, and Setpoints tables. Also, be advised it will reset all CCN proxy...

We trend min and max zone temps(numeric) and min and max zone identifiers(string) every 15 minutes for all the units. I would like to generate a report to identify the worst zone max and min temp...

We have a customer that we are trying to set up some daily email reporting for. The report would include minimum and maximum zone temperatures with identified zone names for each associated AHU.
...

So recently, our mechanical has had an issue with a Trane Intellipak locking out. The faults would be for circuit 1 and 2 compressor trip. Every time it would be both circuits. They were never...

Looking at the CCN tables, they are both writable. I would just modify the equipment file in Snap to be writable via BACnet. I have had to do this is the past.

Glad you got it situated. I'm not familiar with Ivu 3.1.

I'm really have a hard time understanding the issue.

"Yes, I have the issue only in supervisor PC. I exanged for an old (3 months ago, when I didn,t have this issue) hard disk, disconecting the...

What is the network setup? Is there an Ivu Link? What version of Ivu?

I will try.

1) Spyder wire sheets are saved at the Jace level. They are not saved in Spyder controller. They are saved under the virtualXL10 file structure as bog files.
2) Any connecting PC (A...

The station copy includes the config.bog and the complete file structure of the station. (If you choose that option, during the copy).

The backup function includes even more. It includes the...

Seems like you have a conflict of addresses on your chillers. You mentioned you readdressed chiller 3.....that can only only be done with network service tool. In network service tool are the...

Program definition missing, is because you have to define the program.

Example: PROGRAM x {name,description,units}

For every IF statement, you need a ENDIF

If you cant sen me the file, I can...

You would also think by default a backup would grab your alarm and history database. You would also think if it is a Supervisor, by default it would grab your provisioning Jace backups.

It...

Again, it comes down to you need to use Tridium's certificate software to either self sign certificates or generate a certificate for a 2nd party to sign.

How successful has everyone been with...

Been working with Tridium on getting a 3rd party signed wild card certificate to work in Tridium. Going on 2 months now. I feel your pain.

Last statement from Tridium:
"I think that I have a...

Thanks that is really helpful.



We don't control the chiller staging. The chiller controls it's own staging. But I can hold off a compressor. The chillers are redundant. We only give a...
