🧰 Tools You’ll Need

• Screwdriver (Phillips & flathead)
• Smartphone with the Honeywell Home app installed
• Access to your home Wi-Fi
• Masking tape or wire labels
• Voltage tester (optional but recommended)
• Drill (only if you’re installing on drywall without a junction box)

⚡ Step 1: Cut Power to Your HVAC System

Before removing your old thermostat, ensure your safety by turning off power at the breaker panel.

To confirm power is off:

• Try adjusting the temperature on your current thermostat.
• If the HVAC doesn’t respond, you’re good to proceed.

🧯 Step 2: Remove the Old Thermostat

1. Gently pop off the thermostat cover.
2. Take a picture of the wire connections for reference.
3. Label the wires (Y, R, C, W, G, etc.) with masking tape or wire labels.
4. Disconnect the wires and unscrew the old mounting plate.

🛑 Important: Do not let the wires fall back into the wall!

🧱 Step 3: Mount the New Thermostat Base

• Use the included wall plate to cover any unpainted areas or holes.
• Feed the wires through the opening.
• Level the plate and screw it into place using the provided anchors.

⚙️ Step 4: Wire the Thermostat

Match each labeled wire with its terminal on the Honeywell Home thermostat:

Wire	Terminal	Description
R or Rh/Rc	R	Power (24V)
C	C	Common wire (required for Wi-Fi)
Y	Y	Cooling
W	W	Heating
G	G	Fan
O/B	O/B	Heat pump (if applicable)

⚠️ If your system doesn’t have a C-Wire, you may need a C-Wire adapter or power extender kit, usually included in the box.

🔌 Step 5: Attach the Thermostat Faceplate

Once wiring is complete, press the faceplate onto the wall mount until it clicks securely into place.

Now, turn your HVAC system power back on at the breaker box.

The thermostat should power on and begin the setup process.

📲 Step 6: Download & Launch the Honeywell Home App

If you haven’t already, download the Honeywell Home App from the App Store or Google Play. This app is your gateway to remote control and energy monitoring.

1. Open the app and create an account or sign in.
2. Tap “Add Device” and select your thermostat model.
3. Follow the on-screen instructions to:
   • Connect to your Wi-Fi
   • Register your thermostat
   • Complete system configuration

The app will automatically detect your thermostat and guide you through the rest of the setup.

🧠 Step 7: Set Schedules and Preferences

Now it’s time to customize your heating and cooling schedule:

• Wake: Set a comfortable temp for mornings
• Away: Lower energy usage while you’re gone
• Return: Pre-heat or cool your space before you’re back
• Sleep: Optimize for nighttime comfort
