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.

WARNING

Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.

WARNING

To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete.
