IQ4NC — network-oriented controller role

Trend IQ4NC is positioned for IQ network/building automation control, so its network-device duties and configured I/O need confirmation rather than assuming it replaces an IQ4E point-for-point. Document supported controller/network protocols, routing, application software and redundancy or communication-loss behavior before a BMS migration. Critical AHU frost/fire safety functions require standalone appropriately approved interlocks, irrespective of the network platform.
