The Heatmiser Edge Thermostat is a powerful 230v thermostat that offers advanced features and compatibility with wireless accessories such as the wireless air sensor and wireless door/window switch. Whether you want to measure the temperature in another location or have a larger open-plan property, the wireless air sensor function and the ability to use multiple sensors for averaging make it an ideal choice.

Key Features:

  • Wireless Air Sensor Function: The Edge thermostat allows you to measure the temperature in another location using a wireless air sensor. This is especially useful for larger properties or when you want to monitor temperature in specific areas.
  • Wireless Door/Window Switch Function: Pairing a wireless window/door switch with the Edge Thermostat enables automatic switching to Standby Mode when the window/door is open, and returning to normal mode when it's closed.
  • Upgrade Route: The Heatmiser Edge is a great upgrade option for those with existing dial thermostats or for those who want to measure the temperature remotely from the thermostat.
  • Modbus Connectivity: The Edge Thermostat includes Modbus connectivity, allowing seamless integration with home automation and building management systems. This feature enables third-party integrators to control the Edge series and incorporate it into broader control systems.
  • Self Learning Preheat: The Edge-e thermostat offers optimum start, a feature that calculates the required heat-up time for efficient heating.
  • Key Locking: The Edge series includes key locking with a PIN number, providing security and preventing unauthorized tampering with the heating system.
  • Large Display: The Edge Thermostat features a large, easy-to-read display, ensuring clear visibility of temperature and settings.
  • Flexible Programming: Choose between 5/2 day, 7-day, or 24-hour programming options, allowing you to customize your heating schedule according to your preferences.
  • Temperature Control: Enjoy the benefits of self-learning optimum start, 4 or 6 comfort levels per day, and temperature hold for precise control and personalized comfort.
  • Flush Mounting: The Edge Thermostat offers a sleek flush-mount design, seamlessly integrating into your home's aesthetics.
  • Frost Protection: Protect your heating system with the built-in frost protection feature, ensuring that temperatures never drop to damaging levels.
  • Temperature Scale: Choose between Celsius or Fahrenheit temperature scales to suit your preference.
  • Floor Sensor Mode: The Edge series supports floor sensor mode (probe not included) for accurate temperature measurement and control in electric floor heating systems.

Upgrade to the Heatmiser Edge Thermostat and enjoy advanced features, wireless connectivity options, precise control, and a sleek design to enhance your heating experience.
