Herschel T-BT is a compact battery-powered thermostat control designed to work exclusively with Herschel XLS heaters with their built-in SMART-R receiver.

T-BT features a manual temperature mode, a 7×1 day program mode and a holiday (or Away) mode. All modes will operate your Herschel heater(s) by turning them ON if the room temperature is lower than the desired temperature and will turn them OFF once the desired temperature is reached or exceeded.

The T-BT is designed to be easy to operate and incorporates the latest energy-saving features including Herschel’s open window technology and an adaptive start function ensuring your room is always at the right temperature with the least energy use.

The T-BT can  be paired to more than one heater meaning multiple heaters within the room can be controlled with the same T-BT thermostat.

The T-BT is not wifi enabled and will not work with the Smartlife App.

Note: 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.
