No, the MIGHTY+ does not suppoert Bluetooth. However, since all necessary settings of the MIGHTY(+) can be adjusted on the device itself, no Bluetooth function is needed for optimal use.
With the + and - buttons, the temperature can be adjusted in 1°C [34 °F] steps.
When double-clicking the power button, the MIGHTY(+) raises the temperature by 15°C [60°F] - to the so called Booster Temperature.
When triple-clicking, the MIGHTY+ offsets the Superboost Temperature, which raises the Booster Temperature by another 15°C [60°F].
