Desperate-need Trane LCI help

[incontrol]

Using R2. I have been trying to bring in a LCI board on a Reliatel unit and it is a POS. I can't find any help on the trane or Niagara websites. I linked to NVISetpoint and the NVOEffcitveSetpoint is floating around 50-53 and will not change. There is also a NVOSetpoint that reads 0. I can't see how to set an NCI. How does the thumbwheel work on a network (not wired up now).

I am very disappointed in the valuse available too. There is only Occ & Unocc modes, heat or cool mode-not indicating whether gas or compressors are really on, no seperate alarms-lumps 20 into 1.

I've integrated 2 different models in R2... the first one, there were no shadow fitting the model (I don't have the exact number but I think it was something like a LCI-C CH530...), so I had to use a dynamic device. I've got trouble with that one because all variables found by the dynamic device were named "var_x"... so I had to translate those var_x to the true variable names with the xif file I got from Trane.

The second one (model : LciC80002A5028030408) worked great with the good shadow.

For both models, I used program blocks (TRIPL) that translate the information for the station use (and/or comprehension)

For your device, I would check what I get with a dynamic device... maybe that could help

Concerning nci, for both models I didn't have to modify nci (in fact, the dynamic device never found the nci, and the second one, there was nothing to be changed...)

Finally, I'm not sure I know what you mean by thumbwheel, so I cannot help you with that (sorry)... And those two LCI were connected to chillers, maybe it's totally different from your unit.

Hope I could help a little.

Good luck

You will need the XIF for an LCI-R board and you will need to make sure it is set up with the proper image for DAC or SCC. All files are available on the LONMARK website. It seems that other DDC systems... JCI, TAC and such has problems integrating to the LCI. But remember, it is an Lon device, it follows the protocol set by Echelon. You must make sure you are setting up your heartbeats, send receive times, and if the NVI / NVO are ack response or other. If there is a stat wired to the RTU and you send a NVI Space Temp the NVI has the authority. IF you need more documentation let me know and I may be able to assist.

There are several styles of LCI'S for Trane devices and you must use and set up the proper one.

Some times Trane is a little behind with updating the xif files on the LonMark site. The xif in your device might be a newer model than the one at LonMark. It is always best to 'upload' the configuration from the controller (LCI)

Can you give me an example of the TRPL you spoke of. I'm having to convert all kinds of things. I did a learn and it correctly picked the LCIRV2 shadow.
