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.
