Wiser Electrical Heat Switch

The Wiser Electrical Heat Switch is a versatile addition to Schneider Electric's Wiser 2nd Generation smart  home system, enabling precise control over various electrical heating devices. This article outlines its purpose, functionality, and installation process to assist you in integrating it seamlessly into your smart home setup.

1. For What Purpose?

The Wiser Electrical Heat Switch is designed to provide smart control over electrical
heating appliances, including:

• • Electric Underfloor Heating Systems: Manage and schedule underfloor
  heating to optimize comfort and energy efficiency.
• • Electric Radiators and Towel Rails: Control these devices remotely, ensuring
  rooms are warm when needed and conserving energy when unoccupied.
• • Infrared Panel Heaters: Integrate these heaters into your Wiser system for
  centralized control and scheduling.
  By incorporating the Wiser Electrical Heat Switch, you can achieve:
• • Enhanced Comfort: Ensure your living spaces are heated according to your
  preferences and schedules.
• • Energy Efficiency: Reduce unnecessary energy consumption by automating
  heating based on occupancy and time.
• • Remote Control: Manage your heating devices from anywhere using the Wiser
  Home app.
• 2. How Does It Work?
  The Wiser Electrical Heat Switch operates by:
• • Relay Control: Utilizing a 16A relay to switch electrical heating devices on or off,
  handling significant electrical loads safely.
• • Wireless Communication: Connecting via the Zigbee protocol to the Wiser
  Hub, facilitating seamless integration into the Wiser ecosystem.
• • Temperature Regulation: When paired with a compatible thermostat (sold
  separately), it regulates room temperature by controlling the connected heating
  device based on the desired setpoint. For electric underfloor heating
  applications, a remote floor sensor is required to define high or low-temperature
  limits.
• 3. How to Install It?
  Important: Installation involves working with mains voltage electricity. If you are not
  confident in performing such tasks, please consult a qualified electrician.
  Preparation:
• 1. Power Down: Ensure the mains supply to the circuit where the Heat Switch will
  be installed is switched off to prevent electrical shock.
• 2. Verify Compatibility: Confirm that the heating device's electrical load does not
  exceed the 16A rating of the Heat Switch.
  Installation Steps:
• 1. Mounting the Heat Switch:
• a. Location Selection: Choose a suitable location near the heating device,
  ensuring it is accessible for wiring and within range of the Wiser Hub for
  reliable communication.
• b. Surface Preparation: Prepare the mounting surface, ensuring it is clean
  and dry.
• c. Cable Entry: Pierce the rubber grommets to allow cable entry,
  maintaining the IP44 ingress protection rating.
• 2. Wiring Connections:
• a. Cable Insertion: Insert the appropriate cables through the grommets into
  the Heat Switch enclosure.
• b. Secure Connections: Connect the live (L) and neutral (N) wires to the
  corresponding terminals, ensuring all connections are securely
  tightened.
• c. Earth Continuity: If required, use the provided terminals for linking
  external earthing conductors.
• d. Cable Clamping: Secure the cables using the provided cable clamps to
  prevent strain on the connections
• 3. Finalizing Installation:
• a. Seal Openings: Use the supplied blanking plugs to seal any unused cable
  entry points, preserving the device's ingress protection.
• b. Mounting: Fix the Heat Switch to the prepared surface using appropriate
  fixings.
• 4. Pairing with the Wiser System:
• a. Power On: Restore power to the circuit.
• b. Initiate Pairing Mode: Press and hold the button on the Heat Switch for
  more than 2 seconds until the LED alternates between amber and green,
  indicating it is in pairing mode.
• c. Wiser Home App Integration: Open the Wiser Home app, navigate to the
  device pairing section, and follow the on-screen instructions to add the
  Heat Switch to your system.
• d. Confirmation: Upon successful pairing, the LED will flash green for 5
  seconds. If pairing fails, the LED will flash red for 5 seconds; in this case,
  repeat the pairing process.
• 5. Configuration:
• a. Assign to Room: Within the Wiser Home app, assign the Heat Switch to
  the appropriate room or zone.
• b. Set Schedules: Configure heating schedules and preferences to suit your
  lifestyle, optimizing comfort and energy usage.

Heat Switch Installation Guide.
By carefully following these steps, you can effectively install and integrate the Wiser
Electrical Heat Switch into your Wiser 2nd Generation system, enhancing the
intelligence and efficiency of your home's heating management.
Note: Always ensure compliance with local electrical regulations and standards during
installation.
