Stuff to keep in mind:
If the BCU is a model BMTW you will need to install a Lon/comm5 card in the BCU. If it's a model BMTS you cannot use Lon and must replace the BCU. Also the Intellipak must be a certain software version to support the Lon option (see below). The Intellipak Lon cards make it a SCC or DAC, even in Summit. Summit converts the Peak database NVs to Bacnet Objects and Properties. You will not be able to see the NV or do any bindings in Summit. Summmit does the conversion by using group bindings to the pre-selected NVs that Trane wants to use. If you want to use all the NVs in Summit then make yourself an XIF file (or DL at lonmark.org) and create a Summit GLD. You can create your own I/O property bindings to the NVs you want. Summit will not let you do any Lon bindings from one controller to the next. Rover will but it has to be done after Summit has formatted the network.
Most all our jobs are entirely Lon now. Mostly Trane equipment but we do a lot of Lon to kw meters, flow meters, lighting, pressure sensors, VFDs, etc. All these come into Summit as GLDs (Generic Lon Devices). Summit currently only supports SCC, DAC and Chiller profiles, everything else in considered a GLD. Only times I really run into problems is when the Lon controller is a piece of crap engineering. Like TSI, real junk!
LCI Backward Compatibility
This information applies to: INTELLIPAK ROOFTOP 20-130
To install a LCI in an existing unit:
Intellipak Rooftop Units or Air Handlers must have the following software versions for proper LCI-I operation:
RTM Version 20.05 or greater
HI Version 26.04 or greater
VOM Version 2.0 or greater (this is an optional module)
To verify software versions, press the CONFIGURATION button on the human interface, then press the NEXT
button until the software revision screens are displayed. If the version displayed is the same or higher than the
version listed above, then the unit is compatible. If the version number is lower, some unit functionality may be
lost and module change(s) are required. Units with design sequence “5” (20-75 ton) or “X” (90-130 ton) or
greater are shipped with compatible modules. The design sequence is the 10th digit of the model number.
