What is Pro Setup?

Pro Setup is an advanced Nest Learning Thermostat setting to enable installation professionals to set up complex systems, including dual fuel systems, humidifiers and dehumidifiers.

What is Pro Setup?

Pro Setup is required to set up dual fuel systems (e.g. heat pump with furnace) as well as humidifiers and dehumidifiers. It is available to installation professionals during and after installation and allows them to set which wire has power and what kind of equipment it controls, including fuel type for each stage of a dual fuel system.

Who should use Pro Setup?

Pro Setup is only required if you are setting up a complex system like a dual fuel system, a humidifier or a dehumidifier. The vast majority of home systems compatible with the Nest Learning Thermostat do not require Pro Setup and are handled through the normal setup flow and the Equipment setting.

Since making mistakes to the advanced options available in Pro Setup can result in malfunction of your HVAC system, Nest strongly advises that only trained installation professionals use Pro Setup.
