Google Nest Learning Thermostat (4th gen) Installation Guide
Installation Overview - Step-By-Step
1.
Confirm system compatibility
a.
Before opening the Nest Learning Thermostat package, check all the wires connected to the
current thermostat against the list of available connectors in this guide, or use the Compatibility
Checker to quickly verify if the system is compatible. Note that the compatibility checker may
suggest checking with a pro. In that case, this guide is the best reference to determine
compatibility.
2.
Briefly test the HVAC system
a.
Test the heating, cooling, fan, and other system features with the current thermostat before
installing the Nest Learning Thermostat so you can address any existing issues.
b.
At times, outdoor weather conditions may prohibit testing of heating or cooling. In those cases,
inform the customer that you cannot test and ask the customer about the system’s operation
and performance.
3.
Turn off power to the HVAC system
a.
Turn off the power to the system to protect yourself and the equipment. Locate the circuit box and
check to see if the circuits are labeled or if there is a circuit directory. Turn off all HVAC system
circuits.
b.
If you cannot determine which circuits belong to the HVAC system, turn off the main circuit
breaker aſter obtaining permission from your customer. Confirm the power is off by aꢀempting
to activate the HVAC system using the existing thermostat.
4.
5.
Remove the old thermostat
a.
Before removing the old thermostat, take a quick picture of the wiring with your phone in case you
need it for reference. Disconnect the wiring and remove the old thermostat. Use the wire labels
included in Nest Thermostat Installation Guide if needed. Be sure to leave the original thermostat,
hardware, and any jumper wires with the customer. Remember that jumper wires are not needed on
Nest thermostats.
Offer the customer installation finishing options
a.
You may need to cover up holes, old paint, or marks leſt by the old thermostat. Ask your customer if
they prefer to repair the wall themselves or if they want to have the Nest trim plate installed.
the customer know that the trim plate can be painted to match the wall.
