Does Nest Work with Trane?

Nest thermostats are compatible with Trane HVAC systems, including both standard residential units and some specialized commercial equipment. To ensure compatibility, it is essential to check the wiring setup of your existing Trane thermostat. Nest thermostats typically require a six-wire setup, and some Trane thermostats may use proprietary gear that might not be immediately compatible.

Replacing a Trane Thermostat with a Nest Model

When replacing a Trane thermostat with a Nest model, it is crucial to follow the recommended wiring configurations. For instance, in a system with two zones and a heat pump, the wiring should be as follows:

Top Picture Wiring Configuration

Wire Color Trane Thermostat Terminal Nest Thermostat Terminal
White W1 W2 or W (set as Aux heat)
Red R Rc or R (jumper not needed)
Orange O OB or */OB
Yellow Y Y1 or Y
Green G G
Black B C

Bottom Picture Wiring Configuration

Wire Color Trane Thermostat Terminal Nest Thermostat Terminal
Red R Rc or R (jumper to RC not needed)
Orange O OB or */OB
Yellow Y Y1 or Y
Green G G
Blue B C

The “or” in the wiring configurations refers to the Google Nest Thermostat Wiring.

It is also important to note that the jumper between the R and RC terminals is not needed with any Nest thermostat, as it will automatically jump the terminals together if needed. Ensuring all wires have a bright, shiny appearance and are straight, and keeping the bare length only long enough to properly sit in each terminal, can help avoid potential issues during installation.

Manufacturer Support and Updates

Trane and Nest both provide ongoing support and software updates for their products, ensuring compatibility and optimal performance over time. It is essential to check with both manufacturers to ensure that your specific HVAC system and Nest thermostat model are fully compatible and supported.


In conclusion, Nest thermostats are compatible with Trane HVAC systems, but it is crucial to check the wiring setup and follow the recommended configurations to ensure a successful installation. Nest thermostats offer advanced energy efficiency features and smart home integration, making them a valuable addition to any modern household.
