center. All these devices are linked together and communicate using ClimateTalk
language protocol. The benefi ts of ClimateTalk are auto-confi guration of the system,
the ability to share information throughout the system for enhanced diagnostics and
control, and straightforward wiring since communications requires attaching only four
wires. This ensures simple, reliable operation and an accurate installation.
