Learning Thermostat

Installation Guide

ContentsCompatibility

Based on Nest’s online compatibility checker data, the Nest

Thermostat works with most 24V systems, including gas,

electric, oil, forced air, variable speed, heat pump 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 * connector can accept only one

of these wires: 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)

• Whole-home humidifiers and dehumidifiers

Go to nest.com/works to make sure the Nest Thermostat will work

in your home and find out if you need professional installation.

5. Label wires

Peel off the blue labels and attach them to

your wires. Use the white labels if you have a

E, W3, HUM or DEHUM wire. You can connect

only one of these wires to the * connector.

See two labels for each connector?

1. Switch off power

This protects you and avoids blowing a fuse

in your equipment. Adjust the temperature

on your old thermostat to make sure your

system is off.

2. Remove cover

Some covers pop off, while others need

to be unscrewed.

CAUTION: Do not connect Nest to

high voltage wires.

Remember, the power to your

HVAC system must be off to avoid

blowing a fuse in your equipment.

4. Remove any jumper wires

Jumper wires are short wires between two

connectors. You won’t need them. An R wire

can go into either Rc or Rh.

3. Check your system

If your old thermostat is labeled 120V or 240V

or has thick wires with wire nuts, your system

is high voltage. Not sure? Contact support.

6. Disconnect wires and

remove base

7. Mark where screws will go

Use the bubble level to make sure the

Nest Thermostat is level.

Tip: Take a

picture of the

wires on your

old thermostat

to help you

remember.

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.

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.

Optional in most homes
