1 Your system requires advanced configuration and wiring. If you have one of these systems, Contact a Local Pro.
Important: Professional installation is recommended for some systems since their wiring and setup can be complicated. These include:
• Dual fuel systems (heat pump with furnace)
• Dual transformer systems (systems that have more than one R wire)
• Whole-home humidifiers and dehumidifiers (compatible with Nest Learning Thermostat only)
2 Nest thermostats can only support one of these systems at a time.
