Introduction to Thermostat and Communicating  
System  
The system consists of a premium indoor furnace or air handler, an outdoor AC  
condensing unit or heat pump and touchscreen thermostat that is the HVAC command  
center. All these devices are linked together and communicate using ClimateTalk  
language protocol. The benefits of ClimateTalk are auto-configuration 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.
