Setting Up the Hive Hub

The Hive Hub acts as the central link between your thermostat, receiver, and smartphone app. Follow these steps to get it connected:

  1. Locate a Suitable Power Socket and Router Port: Ensure you have access to both a spare power socket and an available Ethernet port on your Wi-Fi router.

  2. Connect the Hub to the Router: Use the provided data cable to link the hub to your router. Plug one end into the hub and the other into the Ethernet port on the router.

  3. Power Up the Hub: Connect the power cable to the hub and plug it into the socket. Turn on the socket to power the hub.

  4. Wait for the Hub to Update: When powered, the hub will begin updating its software. This process can take up to 15 minutes. During this time:

    • The green light will flash to indicate activity.

    • Wait for the green light to become solid and the amber light to flash, signalling the hub is ready to pair.

By setting up the hub first, you allow it to complete updates while you work on the rest of the installation.


Replacing the Existing Programmer

The Hive receiver replaces your existing heating and hot water programmer. Here’s how to make the switch:

  1. Turn Off Power: Confirm the heating system is off at the mains and use a voltage tester to double-check.

  2. Remove the Current Programmer: Unscrew the programmer from the wall. Carefully pull it away to expose the wiring baseplate.

  3. Check Compatibility: Some Hive receivers are compatible with existing programmer baseplates. If it fits, you can leave the baseplate in place. If not, proceed to replace it.

  4. Install the Hive Receiver Baseplate: Remove the existing baseplate and install the Hive baseplate. Ensure the wiring matches the labels on the new receiver for heating and hot water.

  5. Secure the Receiver Unit: Attach the Hive receiver to the baseplate, tighten the screws underneath, and ensure it clicks into place securely.

Replacing the programmer with the Hive receiver is straightforward as the wiring connections usually follow the same format.

Installing the Hive Receiver

Connecting the Hive receiver involves proper wiring. Here’s how to do it safely and correctly:

  1. Examine the Existing Wiring: Identify and label the wires connected to your current programmer. Typical labels include:

    • Heating on/off

    • Hot water on/off

    • Neutral

    • Live

  2. Connect the Wires to the Hive Receiver: Match the labelled wires to the corresponding terminals on the Hive receiver baseplate. Follow the installation guide to ensure accurate connections.

  3. Secure the Wires: Tighten the screws for each terminal to secure the wires in place, ensuring there’s no loose or exposed wiring.

  4. Mount the Receiver Unit: Attach the Hive receiver to the baseplate. It should click into place firmly. Tighten the bottom screws to keep it secure.

With the wiring complete, the receiver is ready to control your heating and hot water.



Testing the Receiver

Before pairing the system, confirm the Hive receiver is functioning correctly:

  1. Turn On the Power: Restore power to the heating system and ensure the Hive receiver’s indicator lights up.

  2. Manual Operation Test:
