We have a CCN that we have had pretty good luck with for the last few years. But now, we have replaced one of the fan coil boards. Since this is a newer version (2.2 to 3.0) we had to blow out the program and manually add everything. The only problem is we can not force any setpoints, we get CCN access denied, but only on this board, all the others still respond correctly. Anybody have any ideas? Thanks.
