In one of the buildings we maintain we have 23 wall units that have either Tracer ZN520 or ZN510 boards in them. We have been having trouble with a couple of the units and narrowed the issue down to the boards one a ZN520 and the other a ZN510. We contacted Trane and they said that they have to install the boards and program them on site at a cost of $$$$.
Would it be more feasible/economical for us to purchase the Rover tool and program them ourselves?
Also, we plan on eventually connecting them via LON to our Schnieder Electric DDC. Anyone have good or bad experiences in doing this?
(The building I am talking about use to be a small hospital and the county bought it. Most of the rooms with the fan coil units were patient rooms and are now offices.)
