Herschel T-MTLED SmartLED WiFi Thermostat

Smart WiFi thermostat for Herschel Select XLS LED infrared panel heaters, combining heating and lighting control in one premium wall-mounted controller.

The Herschel T-MTLED SmartLED Thermostat is a compact, mains-powered control designed specifically for use with Herschel Select XLS LED infrared panel heaters featuring built-in SMART-R receiver technology.

This dedicated SmartLED controller allows you to manage both heating and lighting from a single device, giving you full control over room temperature, LED brightness and colour tone (3000K–6000K) for a more comfortable and personalised environment.

For buyers comparing control systems, our Infrared Heating Thermostats Guide explains how SmartLED systems differ from standard WiFi thermostats, wireless controls and traditional room thermostats.

You can also compare wider smart control options through our Thermostats Collection, WiFi Thermostats and Wireless Thermostats.

Smart Control & Connectivity

The T-MTLED includes integrated WiFi connectivity, enabling remote control via the Smart Life App. This allows you to adjust heating and lighting from anywhere, set schedules and optimise energy use around your daily routine.

It is also compatible with Amazon Alexa and Google Assistant, giving you convenient voice control of both temperature and lighting settings.

• Remote app control from phone or tablet
• Heating schedules and timers
• Lighting adjustment from anywhere
• Voice control through Alexa and Google
• Ideal for smart homes and modern interiors

Heating & Lighting Control Features

• Adjust room temperature with precise thermostat control
• Control LED brightness and colour temperature (3000K–6000K)
• Manual mode for simple day-to-day use
• 7-day programmable scheduling (7×1 format)
• Holiday / Away mode for energy saving when not in use

The thermostat operates your infrared panel automatically by switching the heater ON when the room temperature falls below your chosen setting, and OFF once the desired temperature is reached.

Energy Efficiency Features

The T-MTLED includes advanced energy-saving functions designed to reduce unnecessary runtime and improve comfort.

• Open Window Detection – temporarily switches off heating if a sudden temperature drop is detected
• Adaptive Start – learns how long your room takes to heat and activates in advance
• Energy Monitoring – helps track connected heater consumption
• Smart scheduling – avoids heating empty rooms unnecessarily

To plan a more efficient heating setup, our Heat Loss Calculator is a useful starting point.

Multi-Heater Control

The T-MTLED can be paired with multiple Herschel LED panels within the same room, allowing several heaters to operate together from one thermostat. This is ideal for larger rooms, open-plan areas, studios or commercial interiors where one panel may not be enough.
