How Tado Thermostat Works

Basic Functionality

The Tado thermostat manages your heating by monitoring room temperatures and turning the boiler on or off as needed. It connects to your Wi-Fi network for app-based controls and advanced features like geofencing.

Compatibility with Your Heating System

Tado is compatible with:

  • Combi boilers.

  • Conventional boilers with separate water tanks.

  • Systems with or without a room thermostat. Check your boiler’s manual or the Tado website to confirm compatibility.

Benefits of Using a Smart Thermostat

  1. Energy Savings: Adjust heating schedules and avoid unnecessary heating when no one’s home.

  2. Convenience: Control your heating remotely using the Tado app.

  3. Comfort: Ensure your home is always at the right temperature, no matter the time or season.

  4. Integration: Works seamlessly with smart home systems like Alexa, Google Assistant, and Apple HomeKit.

Preparing for Installation

Removing Old Thermostats

  1. Turn off the mains power to ensure safety.

  2. Remove the cover of your existing thermostat.

  3. Take note of the wiring configuration or photograph it for reference.

  4. Disconnect the wires carefully and remove the unit from the wall.

Checking Boiler Compatibility

  • Refer to your boiler manual to confirm it supports external controllers.

  • Look for terminals labelled for thermostat connections, usually “CH COM” or similar.

  • Ensure there are no conflicts with any existing timer or control systems.

Understanding Wiring Requirements

  • Tado requires connections for live, neutral, and switch live wires.

  • Identify these in your boiler’s terminal block.

  • Remove any pre-installed link wires that bypass the thermostat connection.

Installing the Internet Bridge

Connecting the Bridge to Your Router

  1. Use the supplied Ethernet cable to connect the bridge to an available LAN port on your router.

  2. Plug the micro-USB cable into the bridge and a USB port on the router (or use the included power adaptor).

Ensuring Proper Power Setup

  • The bridge lights should turn on, indicating it’s powered.

  • Wait until all lights stabilise, showing the bridge is connected to the internet.

Checking the Bridge Connection

  • Press and hold the bridge’s pairing button until it starts blinking.

  • Ensure it pairs with the wireless thermostat successfully by observing the connection indicator.

Setting Up the Wireless Thermostat

Activating the Thermostat

  1. Pull out the plastic tab from the thermostat to connect the batteries.

  2. The display will light up, and the device will begin initialisation.

  3. Hold down the thermostat's main button for three seconds until it displays a pairing symbol.

Pairing with the Internet Bridge

  1. Ensure the internet bridge is connected and its lights are stable.

  2. The thermostat will automatically search for the bridge and display a solid connection symbol when paired.

  3. This process may take up to two minutes. If unsuccessful, repeat the pairing steps on both the bridge and thermostat.

Testing the Initial Setup

  1. Adjust the temperature on the thermostat to test communication with the system.

  2. Check that the thermostat responds promptly and shows accurate readings.

  3. Move on to the next step once the connection is confirmed.

Installing the Wireless Receiver

Placing the Receiver

  1. Choose a location near your boiler for easy wiring.

  2. Use the screws and wall plugs provided to mount the receiver securely on the wall.

  3. Ensure the area around the receiver is free from metal obstructions that could interfere with signals.

Wiring Guide for Combi Boilers

  1. Turn off the mains power to the boiler before starting.

  2. Open the boiler’s access panel to locate the wiring terminal block.

  3. Connect the receiver wires as follows:

    • Live (L) and Neutral (N) to the boiler’s corresponding terminals.

    • Switch live (CH NO) to the heating circuit terminal.

    • Remove any link wire connecting the boiler’s thermostat terminals.

  4. Use the Tado manual and your boiler’s instructions to double-check the configuration.

Securing and Testing the Connections

  1. Ensure all wires are tightly secured and no bare wires are exposed.

  2. Replace the boiler panel and turn the mains power back on.

  3. Press the test button on the receiver to check if the heating system activates correctly.

Configuring the System

Selecting the Correct Mode (e.g., Combi Boiler)

  1. Access the receiver configuration by holding down the buttons for five seconds.

  2. Use the heating button to select the appropriate mode:

    • Yellow light for combi boilers.

    • Other colours for different systems (refer to the manual).

  3. Wait for the receiver to confirm the mode with a steady light.

Adjusting the Settings for Your Home

  1. Use the app or thermostat to set your preferred temperatures.

  2. Enable features like scheduling and geofencing to optimise heating times.

  3. Fine-tune the thermostat to match your household’s daily routine.

Troubleshooting Common Issues

  1. Thermostat not pairing: Ensure the internet bridge is connected and repeat the pairing process.

  2. No response from the boiler: Check the wiring connections and the boiler’s power supply.

  3. App issues: Update the app and ensure your phone is connected to the same Wi-Fi network.

Benefits of Smart Thermostats

Saving on Energy Bills

Smart thermostats like Tado help optimise heating by turning the system on only when needed. This prevents wasted energy and can significantly lower your gas bills. Features such as room temperature regulation ensure your boiler isn’t running unnecessarily, saving money over time.

Scheduling Heating Times

With Tado’s app, you can create heating schedules tailored to your lifestyle. For example:

  • Set the heating to turn on just before you wake up.

  • Lower the temperature during the day when no one is home.

  • Warm your home in the evening before bedtime.

This flexibility ensures your heating is always working efficiently, meeting your needs without excess energy use.

Geo-fencing and Other Advanced Features

Tado’s geo-fencing feature detects when you leave or approach home using your phone’s location. It adjusts the heating automatically, ensuring comfort when you’re home and savings when you’re not. Additional features include:

  • Remote control via the app.

  • Integration with smart home systems like Alexa or Google Assistant.

  • Intelligent temperature adjustments based on weather forecasts.

Common Mistakes to Avoid

Skipping Safety Checks

  • Failing to turn off mains power can lead to electrical shocks.

  • Not testing wires with a voltage tester might result in accidents.

Incorrect Wiring

  • Connecting the wrong wires to your boiler or thermostat can damage the system.

  • Always double-check wiring diagrams from both the Tado manual and your boiler’s instructions.

Overlooking Boiler Manuals

  • Boiler manuals provide essential details about compatible thermostats and wiring requirements.

  • Ignoring these instructions can result in faulty connections or voided warranties.

Safety Advice for DIYers

When to Call an Electrician

If you’re unsure about any part of the installation process, especially wiring, it’s best to consult a qualified electrician. Miswiring or improper handling of the system could result in serious harm or damage to your boiler.

Avoiding Risks with 230V Connections

  • Ensure the mains power is off before handling electrical components.

  • Work methodically and use insulated tools to minimise risks.

  • Never attempt installations if you’re uncertain about working with high-voltage systems.

Maintaining Your Tado Thermostat

Regular Updates for the App

Keep the Tado app updated to access the latest features and security improvements. Updates often include enhancements that improve system functionality and energy efficiency.

Cleaning the Device

  • Wipe the thermostat and receiver with a dry or slightly damp cloth.

  • Avoid using harsh chemicals, as they can damage the device.

Checking Connections Periodically

  • Inspect the wiring and connections every few months to ensure everything remains secure.

  • Look for signs of wear or loose cables that could affect performance.
