We are quoting a building that has 8 Trane rooftops and are adding 6 more. The owners are looking for a management system, trane is what the spec calls for but they are only asking for the touch screen display. This will not give them full access to the system, I assume, we are going to offer an alternitive lon system. Do the new trane rooftops have lon capability and can we just daisey chain them together into a front end. Our company sells tridium but I have access to honeywell also. What is better and probably more important less expensive or is there a better way to do the building. I put in a Reliable controls system a few years ago in a similar building on some Lennox units and the customer ( same company but different plant) seem to be happy with it. That system only did set back control and supply and return temps. If I can tie into the trane units without a controller that would be very nice.
