1- 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.
2- SAFETY
WARNING
Thermostat installation and all components of
the control system shall conform to Class II
circuits per the NEC/CEC 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.
