Configuring N2 communications
N2-capable controllers support the full range of
possible N2 device addresses provided by the N2
protocol standard (1-254).
To configure a controller to communicate using the
N2 protocol, complete the following steps:
1. Disconnect the 24 VAC supply from the
controller.
2. Set the address switches to the desired N2
address. For details about setting a device
address, see Setting the device address.
3. Reconnect the 24 VAC supply to the controller.
4. Using an SA bus connection, download the
firmware and controller application file
configured for N2 to the controller.
