Key Features:

  • Remote Sensor Compatibility: With the option to use a remote sensor, the Slimline-RF thermostat can measure the temperature up to 20 meters away from the thermostat itself. This enables precise temperature monitoring and control in a specific area.
  • Extended Communication Range: For larger spaces or areas with obstacles, an optional repeater (Heatmiser Boost) is available to extend the wireless communication distance, ensuring reliable and uninterrupted operation.
  • Key Lock Facility: The Slimline-RF thermostat offers a key lock feature, allowing you to restrict access to the system. This feature promotes energy conservation by preventing unauthorized temperature adjustments.
  • Self Learning Preheat: The thermostat incorporates self-learning preheat functionality, which calculates the optimal heat-up time required to reach the desired temperature at the scheduled time. This intelligent feature enhances comfort and energy efficiency.
  • Compatibility: The Slimline-RF thermostat is compatible with Heatmiser UH8-RF, RF Switch, and Boost, providing a versatile solution for various heating setups.
  • Programmable Modes: Choose between heating-only or heating and hot water modes to suit your specific requirements. The thermostat supports non-programmable mode, 5/2 day, and 7-day programming options, offering flexibility in temperature scheduling.
  • 4 Comfort Levels per Day: Enjoy the convenience of setting up to four different comfort levels throughout the day, ensuring optimal temperature control at different times.
  • Optimum Start: The Slimline-RF thermostat includes an optimum start feature that calculates the required heat-up time based on the desired temperature schedule. This ensures your space is comfortably heated when you need it, maximizing energy efficiency.
  • Holiday Function: Planning a vacation? The thermostat's holiday function allows you to set a different temperature during your absence, saving energy while maintaining protection against freezing.
  • Temperature Hold: Use the temperature hold feature to set a specific temperature for a defined duration. Once the set time has elapsed, the thermostat returns to its regular programming, balancing comfort and energy conservation.
  • Remote Air Sensor Connection: Connect a remote air sensor to the Slimline-RF thermostat to measure the temperature in a different location, providing even more precise control over your heating system.
  • Wireless Fail Safe: The thermostat includes a wireless fail-safe mechanism, ensuring reliable communication between the thermostat and receivers even in case of temporary signal disruptions.
  • Frost Protection: Protect your heating system and prevent freezing with the frost protection feature, which maintains a minimum temperature threshold to safeguard your pipes and equipment.
  • °C / °F Option: Choose your preferred temperature unit, switching between Celsius and Fahrenheit for convenient temperature readings.
