General Information
Installation Features
Pro Setup
The Pro Setup process allows a technician to install and configure a Nest Learning Thermostat (4th gen) on their
own phone using the Google Home app even if there is no Wi-Fi available yet. This process is also significantly
faster than the customer install process and allows you to skip through basic instructions. The Pro Setup will
prompt you to enter a Nest Pro ID, which will activate an extended warranty and store company contact
information on the thermostat and in the user's Google Home App. Once you have input your Pro ID with your
Google Home App, it will be automatically filled in on any Nest Learning Thermostats (4th gen) you install in the
future.
Advanced Settings
Pro Setup lets Nest Pros configure advanced settings to set up complex systems, including dual-fuel systems,
humidifiers/dehumidifiers, multi-speed fans, and ventilation systems. It also allows you to adjust settings like
compressor run times, droop, and the maintenance band. Some of these settings are only available during the
Pro Setup process and cannot be adjusted by the user after installation.
Silent Relays
The Nest Learning Thermostats uses solid-state switching instead of relays so there's no noise when it
switches on or off. You will not hear any "clicking" during system testing and activation.
System Match
When you first install the Nest Learning Thermostat, the Google Home App checks to see which wires have been
inserted into the base's connectors and will prompt you for additional information where needed.
Multifunctional Connectors
The Nest Learning Thermostat has two multifunctional terminals, Star(*) and AQ+, that can control several
different applications. When used, the Google Home App will ask you to select the equipment connected to the
terminals. For a list of compatible applications that the multifunctional connectors support, please see the wiring
diagrams below or the Equipment terminal details page above.
Backplate LED
The Nest Learning Thermostat features an LED light on the baseplate that indicates that the thermostat
is receiving power from the equipment. If the LED is illuminated, this indicates that the baseplate is receiving
adequate power from the HVAC system. If the LED remains off, this signifies that the thermostat is not
receiving power.
