Google Nest Learning Thermostat (4th gen) Installation Guide

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 Seꢀings  
Pro Setup lets Nest Pros configure advanced seꢀings to set up complex systems, including dual-fuel systems,  
humidifiers/dehumidifiers, multi-speed fans, and ventilation systems. It also allows you to adjust seꢀings like  
compressor run times, droop, and the maintenance band. Some of these seꢀings are only available during the  
Pro Setup process and cannot be adjusted by the user aſter installation.  
Silent Relays  
The Nest Learning Thermostat 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.  
Baseplate 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.
