Configuring Nest with Pro Setup
How to use Pro Setup
When you set up the Nest Thermostat for the first time, you'll be asked if you're a professional installer. If you
answer "PRO," you'll receive Pro Setup options. Pro Setup can also be accessed at any time after the Nest
Thermostat is installed through the SETTINGS menu. To enter Pro Setup on the Nest Thermostat after the
initial setup go to SETTINGS > EQUIPMENT > CONTINUE > CONTINUE > PRO SETUP. In both cases you will
need to enter your Pro ID which can be found next to your username on the
Nest Pro website.
Pro Setup lets you configure how the Nest Thermostat controls each
wire connected to it. When you first enter Pro Setup, you’ll see an image
of the connectors on the Nest base. Connectors with wires will be
highlighted in green or yellow. Green indicates that the wire has only one
setting. Connectors highlighted yellow have multiple options. The Nest
Thermostat selects default settings for these connectors, but you’ll want
to verify or modify these settings to make sure it is controlling each wire
appropriately.
To configure a wire, just turn the thermostat ring to highlight a connector
and press to select it. Each wire will show Type, which describes the function of that wire. In most cases the
Type cannot be changed - it’s dictated by the wiring configuration and by whether or not the system is dual
fuel. The Type for the Star connector is always customizable.
Connectors that control a heating or cooling function will also have a Source setting (to identify the type of
fuel used to heat or cool), a Delivery setting (to describe how heating or cooling is distributed throughout the
home) and a Fan setting (to activate the fan if required). Depending on the wire configuration, the Source or
Delivery settings may have only one default option.
The Fan default is Don’t activate. This means that the Nest Thermostat will rely on the system to activate the
fan when the furnace (W1) is running. If you test the furnace and notice that the fan is not activating, change
this option to Activate. The Fan setting will only change fan activation when the furnace (W1) is running, the
fan will continue to activate normally during other functions.
Source options:
• Gas
• Electric
• Oil
• Propane (LP)
• Geothermal
Delivery options:
• Forced air
• In-floor radiant
• Radiators
• Electric baseboard
(electric source only)
Fan options:

• Don’t activate
It's recommended that all connectors highlighted in yellow be reviewed to ensure that the options chosen are
right for that system. After selecting the yellow-highlighted connector, any fields needing attention will be
outlined in blue. Press the Thermostat face to enter that field (the entire field will turn blue). Then turn the ring
to select the correct option for your installation. You must complete this process for every yellow-highlighted
connector and every field outlined in blue within those connectors. If there are no connectors highlighted in
yellow you can turn the ring and select DONE at any time to exit Pro Setup.
