Heatmiser Edge Programmable Thermostat – Smart, Wireless & Intuitive Heating Control

The Heatmiser Edge Programmable Thermostat is a feature-rich 230V thermostat designed for modern, efficient heating control. With wireless connectivity for accessories such as wireless air sensors and wireless door/window switches, it offers unparalleled flexibility, precision, and automation. Whether you need to monitor temperatures in different locations or optimise heating in open-plan properties, the Edge thermostat is the perfect solution.

Key Features

  • Wireless Air Sensor Compatibility: Connect a wireless air sensor to monitor temperatures in different locations. Ideal for multi-room properties or areas where precise temperature control is essential. Supports multiple sensors for averaging temperature readings across larger spaces.
  • Wireless Door/Window Switch Function: Pair with a wireless door/window switch to automatically switch to Standby Mode when a door or window is open, preventing energy waste. The thermostat will return to normal mode once the door/window is closed.
  • Seamless Upgrade Option: Perfect for upgrading from traditional dial thermostats or for users who need remote temperature measurement.
  • Smart Home & Building Automation (Modbus Connectivity): Built-in Modbus connectivity enables third-party system integration, making it a great choice for home automation and building management systems (BMS).
  • Self-Learning Preheat (Optimum Start): The Edge-e model features an intelligent preheat function, automatically adjusting the heating schedule based on previous patterns to optimise energy use.
  • Security & Key Locking: Prevent unauthorised adjustments with PIN-protected key locking. Ideal for homes with children or rental properties.
  • User-Friendly Display & Programming: Large, easy-to-read LCD display for clear visibility of temperature and settings. Flexible programming modes – choose from 5/2-day, 7-day, or 24-hour schedules. 4 or 6 comfort levels per day for precise temperature control.
  • Sleek Flush-Mount Design: Slim 15mm depth and modern aesthetics allow seamless wall integration.
  • Frost Protection & Floor Sensor Mode: Frost protection ensures the system never reaches dangerously low temperatures. Optional floor sensor mode (probe not included) for electric underfloor heating control.
