Notes
Intended to run with the Implenia Tunnel Fan Control driver. If configured as a master (leave the three master addresses zero or blank), the driver controls the outputs and fan directly. If configured as a slave (one or more master addresses set - use the last octet of the IP address of the master ezeio), the driver will control the fan speed based on the master setting.
