This device is one of the lowest cost units on the market yet has some features that make it stand out, specifically the three status LEDs which show incoming and outgoing data activity. A yellow Error LED indicates wiring faults in the network. It lights up when nodes have reversed 24VAC polarity.<\/p>\n

Sharing a transformer across devices is common in building automation, making consistent 24VAC difficult. The LED quickly identifies issues, simplifying troubleshooting and debugging.<\/p>\n
