Herschel T-BT Wireless Thermostat for XLS Infrared Heaters
Battery-powered wireless thermostat for Herschel XLS infrared heaters, with simple room control, energy-saving features and support for pairing multiple heaters in one room.
The Herschel T-BT is a compact battery-powered wireless thermostat designed to work exclusively with Herschel XLS heaters fitted with their built-in SMART-R receiver. It is a practical control option for buyers who want straightforward in-room temperature management without relying on WiFi or app-based controls.
The T-BT is especially useful where you want a physical thermostat in the room rather than managing everything from a phone. It suits homes, offices, bedrooms, garden rooms and selected commercial spaces where simple wireless control is preferred.
For buyers comparing control types, our Infrared Heating Thermostats Guide explains the difference between wireless thermostats, WiFi systems, app-based controls and room-by-room infrared heating management. You can also compare product types through our Thermostats Collection, Wireless Thermostats and WiFi Thermostats collections.
How the T-BT Works
The T-BT offers a manual temperature mode, a 7×1 day programme mode and a Holiday / Away mode. In each mode, it operates your compatible Herschel heater or heaters by turning them ON when the room temperature is lower than the desired setting and turning them OFF once the set temperature is reached or exceeded.
This gives you a clear and dependable way to maintain room comfort without needing cloud-based controls or complicated smart-home setup.
- Manual mode for simple everyday adjustment
- 7×1 programme mode for scheduled heating
- Holiday / Away mode for reduced energy use during absences
- Wireless RF control for clean installation and flexible placement
Energy-Saving Features
The T-BT is designed to be easy to operate while still incorporating modern energy-saving features. These include Herschel’s open window technology and an adaptive start function, helping ensure the room is at the right temperature with the least energy use possible.
These features can help improve efficiency by reducing unnecessary runtime and making room heating more responsive to real-life use patterns.

Multiple Heater Control in One Room
The T-BT can be paired to more than one heater, meaning multiple compatible Herschel XLS heaters within the same room can be controlled using a single thermostat. This makes it especially useful for larger rooms, open-plan spaces or layouts where more than one panel is needed to provide the right level of comfort.
Multiple heaters in one room can be paired to a single T-MT or T-BT controller, making room-by-room zoning easier to manage.
Why Choose T-BT Instead of WiFi Control?
The T-BT is not WiFi enabled and does not work with the SmartLife App. That is not a drawback for every buyer. In many cases, it is the main reason to choose it.
- No app needed for everyday control
- No dependence on internet connectivity
- Good for users who prefer a simple physical thermostat
- Strong option for guest rooms, family homes and straightforward room control
If you do want app-based control instead, browsing our WiFi Thermostats collection will help you compare alternatives.
Range, Installation and Important Notes
The wireless RF signal between the T-BT thermostat and compatible XLS panel has a range of approximately 35 metres, making it suitable for typical room layouts and many domestic installations.
If installing in a bathroom, ensure the thermostat is placed in Zone 3 or other dry areas as appropriate. The T-PL plug-in model is not suitable for bathroom use.
Important: The T-BT will only work with Herschel XLS heaters. It is not possible to operate the T-BT with any other brand of infrared heater.
