and radiant. It can control:
• Heating: one, two, and three stages (W1, W2, W3)
• Cooling: one and two stages (Y1, Y2)
• Heat pump: with auxiliary and emergency heat (O/B, AUX, E)
• Fan (G)
• Power (C, RH, RC)
• Humidifier or dehumidifier (HUM, DEHUM)
The Nest Thermostat’s
W3, E, HUM or DEHUM.
The Nest Thermostat is designed to work even if your home doesn’t have a common (C) wire.
Rarely, installing a new C wire may be required.
Professional installation recommended for:
• Dual fuel systems (heat pump with furnace)

old thermostat
to help you
remember.
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.
Snap the base and trim plate together,
then screw them to the wall.
You’ll find the trim plate in the bottom
of the box.
6. Disconnect wires and
remove base
After removing the
base, we recommend
gently wrapping the
wires around a pen or
pencil to ensure they
don’t fall back into
the hole in the wall.
Remember, the power to your
HVAC system must be off to avoid
blowing a fuse in your equipment.

Use the bubble level to make sure the
Nest Thermostat is level.
Optional in most homes
Mounting 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 screws into the long slots
on the steel plate.
Use the other two short screws to attach the
Nest base and trim plate to the steel plate.

FCC Regulatory Statement
This device complies with part 15 of the FCC rules. Operation is subject to the
following two conditions: (1) This Device may not cause harmful interference; and
(2) this Device must accept any interference received, including interference that
may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This Device generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this Device does
cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
This equipment complies with FCC radiation exposure limits set fourth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance of 20 cm from all persons.
IC Regulatory Statement
This device complies with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:
(1) this device may not cause interference, and
