1. Switch off power
This protects you and avoids blowing a fuse. Adjust the temperature on your old thermostat to make sure your system is off.
Breaker Box Switch
2. Remove cover
Some covers pop off, while others need to be unscrewed.
3. Check your system
If your old thermostat is labeled 110V or 220V or has thick wires with wire nuts, your system is high voltage. Not sure? Contact support.
CAUTION: Do not connect Nest to high voltage wires.
4. Remove any jumper wires
Jumper wires are short wires between two connectors. Nest doesn’t need them. An R wire can go into either Rc or Rh.
5. Label wires
Peel off the blue labels and attach them to your wires.
Tip: Take a picture of the wires on your old thermostat to help you remember.
6. Disconnect wires and remove base
Tip: Wrap the wires around a pencil to keep them from falling into the wall.
7. Mark where screws will go
Use the bubble level to make sure Nest is level.
Optional in most homes
Use trim plate if needed
You can cover up holes or marks left by your old thermostat with the optional trim plate.
Place the trim plate on the wall and put the base on top so they snap together, then screw them both to the wall.
The trim plate can be found in the bottom of the Nest box.
Optional in most homes
Mounting Nest on an electrical box
Electrical boxes aren’t common, but if you have one, secure the steel plate to the electrical box with two of the short steel plate screws. Insert the steel plate screws into the long slots on the steel plate.
Use the other two short steel screws to attach the Nest base and trim plate to the steel plate.
8. Attach base
9. Connect wires
After all wires are connected, make sure they’re flush with the wall.
