Installation overview
What’s different about installing Nest
No jumper wires needed
Discard any jumper wires on the old thermostat. Nest won’t need them.
System Match
Nest senses what wires are connected and asks you a few questions so it can offer different features
specifically for your customer’s heating and cooling system.
Pro Setup
Pro Setup is an advanced setting to enable you to set up complex systems, including dual fuel systems
humidifiers and dehumidifiers.
Silent relays
Nest uses solid state switching instead of relays so there’s no noise when Nest switches on or off.
Press connectors
Just press and insert the wires from the heating and cooling system into Nest, just like speaker wire
connectors.
Installation check-list
✓
Briefly test the HVAC system with existing thermostat.
Make sure everything works before you install Nest. You’ll be able to identify any HVAC issues and
it’ll help you isolate the appropriate circuit breaker for turning the HVAC system off.
✓
Turn of HVAC power at the furnace or circuit breaker.
Turning off the power to the system while replacing the thermostat protects both you and the
equipment.
✓
Determine wiring compatibility before opening Nest packaging.
Just a simple test: would all the wires on the current thermostat have a home on Nest’s base?
Take off the cover of the old thermostat and look at the wires. Check them against the list of
available connectors on the box or visit nest.com/works.
✓
Take a photo of the old thermostat wiring.
If you can, take a quick picture of the old thermostat wiring. A reference photo can be handy when
checking Nest’s wiring.
✓
Offer the customer installation finishing options.
Nest can be installed directly on the wall or with the optional trim kit. Talk to your customer about
what they prefer.
✓
Trim and re-strip the wires.
Most thermostats have the HVAC wiring wrapped around terminals, leaving wires bent and
difficult to insert into Nest’s press connectors. A quick trim and strip will make life much easier.
✓
Walk through the setup interview with your customer.
Most of Nest’s setup questions are easy for a professional to answer, but some answers, like a Wi-
Fi password, only the customer can provide.
