1. Gathering Your Supplies and Preparing for Installation

Before you begin, gather the necessary tools and materials:

Your new Ecobee Premium thermostat: Make sure you have the correct model.
Screwdriver (likely Phillips head): To remove the old thermostat and secure the new one.
Wire strippers/cutters (optional): In case you need to adjust wire lengths.
Voltage tester (highly recommended): To ensure power is off before working with wiring. Safety first!
Pencil or marker: For labeling wires.
Camera (optional): To take photos of your wiring before disconnecting. This is crucial for accurate reconnection.
Level: To ensure your new thermostat is mounted straight.

2. Safely Disconnecting Your Honeywell HZ311 Thermostat

Safety is paramount. Turn off the power to your HVAC system at the breaker box. Use the voltage tester to confirm power is off at the thermostat wires.

Remove the thermostat cover: Gently pry off the cover of your HZ311 using a flathead screwdriver, if necessary.
Take photos: Take clear pictures of the wiring connections. Note the location of each wire on the thermostat base. Label each wire with a pencil if you prefer. This step is incredibly important for easy reconnection later.
Disconnect the wires: Carefully unscrew the wire nuts connecting the wires to your HZ311 thermostat. Keep track of which wire goes where.

3. Preparing the Ecobee Premium for Installation

Unpack the Ecobee: Carefully remove the Ecobee Premium from its packaging. Examine all components.
Review the Ecobee instructions: Familiarize yourself with the Ecobee's installation guide.
Mount the baseplate (if necessary): Some installations may require mounting a baseplate first. Follow the Ecobee's instructions for this step.

4. Connecting the Wires to Your Ecobee Premium

This is where your photos from step 2 come in handy! Carefully connect the wires from your HZ311 to the corresponding terminals on your Ecobee Premium. Refer to the wiring diagram in your Ecobee manual. It should be very similar to the HZ311, though some wire colors might differ.

Common Wire Connections:

R (Red): Power
G (Green): Fan
Y (Yellow): Cooling
W (White): Heating
C (Blue/Light Blue): Common (essential for most smart thermostats)

Important Note: If you have any additional wires (like O/B for heat pump systems), refer to both your old thermostat's wiring diagram and the Ecobee's instructions. Incorrect connections can damage your HVAC system.

5. Mounting and Testing Your Ecobee Premium

Mount the thermostat: Securely mount the Ecobee Premium to the wall using the provided mounting hardware. Ensure it is level.
Turn on the power: Turn the power back on at the breaker box.
Power up your Ecobee: Follow the on-screen instructions to complete the Ecobee Premium setup. This includes connecting to your Wi-Fi network and creating an account.
Test the system: Verify that heating and cooling functions work correctly. Check the fan and adjust the temperature to test the responsiveness of the system.

Troubleshooting Common Issues

No power: Double-check the breaker and your wiring connections.
Incorrect heating/cooling: Verify your wire connections again. Consult the Ecobee's wiring diagram for assistance.
Wi-Fi connection problems: Ensure your router is close enough and your Wi-Fi password is correct.
