Google Nest Learning Thermostat T3050US
Compatibility
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.

INSTALLATION
- 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.
- Remove cover
Some covers pop off, while others need to be unscrewed.
- 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.
CAUTION: Do not connect Nest to high-voltage wires. - 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.
- 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?

Tip: Take a picture of the wires on your old thermostat to help you remember. - Disconnect wires and remove the base
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.
- Attach base

After all the wires are connected, make sure they’re flush with the wall.

Nest Labs, Inc. Limited Warranty Learning Thermostat
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.
- 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.
