11.1.13 Metasys N2 (RS485) + 2 pulse inputs (VA, VB) (67-00-62) (PCB - 5550-1110) The N2 module is used for data transfer from MULTICAL heat and cooling meters to an N2 Master in a Johnson Controls System. The N2 module transfers accumulated energy and volume, current temperatures, flow and power from the heat or cooling meter to an N2 Master. N2 Open from Johnson Controls is a widespread and established field bus protocol used within building automation. The N2 module for MULTICAL ensures simple integration from Kamstrup’s heat and cooling meters to N2 Open based systems. Adress area is 1-255 determined by the last three digits of the meters customer number. Further details about the Metasys N2 module appear from data sheet 5810-925, GB-version.
