N2 communications are installed on the Model 8636-N2 room pressure controllers. This document
provides the technical information needed for the host DDC system to communicate with 8636
units. This document assumes the programmer is familiar with the N2 protocol. Further technical
assistance is available from TSI if your question is related to TSI interfacing to a DDC system. If
you need further information regarding N2 programming in general, please contact Johnson
Controls.
