The WCI devices communicate BACnet Zigbee back to the Tracer SC's WCI. I believe the hardwired communication protocol from the WCI to the SC is some form of IMC communication (proprietary to Trane)....

I have a copy of it that I can send you. I am not sure of the exact date that Trane stopped producing these controllers, but I will say that you stopped seeing them installed around 2008. The MP580...

I have a job site that has a old 1993 HydroTherm S-8 control panel that is used to stage multiple boilers. I was wondering whether anyone has a manual for one of these? I can't seem to find one...

I have successfully integrated a new Trane Centaurus Prime gateway into the NAE sitting under a Johnson Controls Metasys system. I was on site performing some testing today and I noticed that...

Remind me of the Cylon software you're using? Is it called Command Centre? If so, it isn't something that was used in America and I am not very familiar with it. If you're working in Unitron...

Thank you for this information! Is MCT built into SCT? Or is it a totally separate application?

I believe the customer has SCT running on the ADS server. I will look into using that tool later this week. Thank you for your reply!

I have been tasked with integrating a Trane RTU Gateway into a NAE on a older Johnson Controls Metasys system. I have worked around Metasys for awhile, but have never had to add multiple devices and...

Thank you everybody for all of the feedback.

I will say that drawing provided by the mechanical engineer isn't 100% accurate. There was really no work performed on the condenser side of the...

Since we're talking about bypass valves. I was wondering if anyone has seen a bypass valve installed like the one on the drawing below? On every single job that I have been a part of the bypass...

The chillers are Daikin WME (magnetic bearing). The chiller struggles with getting the lift pressure up after the transition.

I am already doing that for a set amount of time. The customer doesn't want the chilled water temperature to get too high when transitioning, so I have some limitations. I will keep pushing them to...

The piping on this system is very large, so it isn't cheap to get the bypass valves installed. That is the reason why they are asking me to do things that aren't normal. Trust me, I have mentioned...

I have a customer who isn't wanting to spend the money to install a bypass valve on their condenser water loop/ cooling tower right now. The system in question has a plate and frame heat exchanger...

We have a customer who has Reliable Controls. They have been having a ongoing issue on a application with pneumatic VAV boxes. They're using the Reliable Controls MPA 33 VAV controller to send a...

Thank you for your reply! Very helpful information!

I can look into the Lonworks option. Just to make sure that I have all of my bases covered, I want to make sure that I have the right hardware...

I have a customer with a Tracer Summit system that communicates to some Trane Intellipak RTUs (TCI) and some Trane VAV boxes (UCM) over Comm4. This particular customer wants to replace their RTUs...

I have a customer with a TAC Vista system that used to email them alerts/ alarms, but doesn't seem to be working any longer. I started to look into the issue and I found the "Alarm Receivers" for...

That is what I was afraid of. Thank you for your feedback!

I have a job site that has some Trane ZN517 controllers installed on some fan coil units (hot water and chilled water). I reviewed the manual for this controller and it indicates that a humidity...

You can utilize polygons and setup mouseovers by adding/ configuring the properties of the polygons. A polygon will allow you to plot points over your floorplan irregularly until you complete the...

I was sent the files to convert the RTU Open from VAV to CV (opposite of what you have going on). We reviewed all of the options with the general contractor, engineer, and Carrier. In our case, we...

I have a building that has (2) Trane Intellipak RTUs that were installed about 3 years ago that will randomly send "Diagnostic - Invalid Unit Configuration" down to the Tracer SC+/ Synchrony system. ...

If you can send over the files that may be helpful. Based on Balibe's response it sounds like there is quite a bit of work involved with this conversion (outside of the programming requirements). ...

Thank you for this information. These are some of the things that I fear. We have been working with Carrier on this. I just received word from Carrier that they are going to provide us with...

This residential zone damper system is designed to operate at .5" w.c. They ordered this RTU with a high static fan rated at 1.5" w.c. These residential zone dampers have cheap low torque actuators...

It isn’t a VAV system. It is a low pressure Honeywell residential zone damper system with standard thermostatic control. Right now the unit can’t take in commands from a system like this. The...

I have been brought into a project gone wrong and I had a few questions in regards to some Carrier RTUs with a RTU Open Boards.

There were some existing RTUs with standard thermostatic control...

Thank you for the information. This is very helpful!

This ended up working out for us on certain units. Is there a way to do this on the PremierLink RTUs? Can a centralized SNAP program be stored in one of the controllers and we simply reference it...

I have a customer who has (4) large pressurization fans for their smoke management system. The fans are used for the stairwells and hoist ways for some elevators. The installing contractor didn't...

Thank you for all of the replies! This site does have Lonmaker installed and I reviewed all of the different Visio files that show all of the SNVTs/ references and nothing shows how they're getting...

I have a site with a TAC Vista system. I am trying to track down a outside air temperature reference and I am having a hard time figuring out what all it goes to and in some cases where it is coming...

What kind of i-VAV controllers are you dealing with? Are they TSC iVAV controllers or TLC iVAV controllers? This is very important to know because a TSC iVAV controller isn't BACnet visible. In...

I have a lot of experience with Teletrol eBuilding systems. I have integrated certain portions of Teletrol eBuilding into a Tridium N4 system before. What all are you trying to do? Are there...

No unfortunately not. You will need Tracer TU to get TGE to edit graphics.

Oh okay. I will look into that with the startup technician.

We only have one bypass valve output but we have two chillers. Which chiller takes priority control over the bypass valve/ cooling tower VFD speed? It makes sense to ramp the chillers together, but...

I am working on a project with two Daikin WME Magnitude chillers with a common condenser header, a single bypass valve, and two cooling towers with VFDs. The Daikin startup technician, the Daikin...

Thanks for the information. Yeah, I have more experience with the BCU as well. Setting up LON devices under Tracer SC is still pretty new to me. I have replaced devices like VV550 controllers and...

I believe the protonode has a way for me to input the DSN through its field server interface. I do wonder how to determine what domain the SC is looking for. Does the Rover tool in active mode show...

Thank you for your reply! I do have a copy of the Rover service tool. I have always wondered when I would need to utilize active mode. I have only used passive mode. I don't have NlUtil and...

I have a building with a Tracer SC that has a Lonworks protonode with three Paterson Kelley boilers connected to it. The customer just had one of their boilers changed out with a newer Patterson...

I doubt that these credentials will work. Most contractors don’t use default credentials.

I saw you tried to email me as well.

I have a lot of documentation. However, most of my training documentation is in large lab books. I would have to check on what I have over electronic. I...

Yes, you’re correct. Integra is just a ABB branded JACE. It is very similar to Distech. The Distech JACE uses a BCP network with built in tuning policies and functionality for their controllers...

When your setpoints aren't matching what you're sending it is almost always a scaling issue. Even though a GBAS module may be rated for 0-5 VDC (as an example) you may have to have your scale set at...

I have included product data sheets for the Matrix, Nexus, and Enterprise below so you can compare certain specifications.

The Nexus and Matrix are Aspect's version of a JACE. The only difference between the two controllers is the type of devices they can integrate and the amount of project resources they can handle. A...

We you go to setpoint source selections, do you see the discharge air cooling setpoint? If so, what does it say next to it? (Human Interface)? When you use the + and - buttons what options do you...
