Make your gas boiler and underfloor heating smart
The room thermostat II 230 V controls underfloor heating, gas boilers, radiator thermostats and other wired heating systems intelligently and efficiently.

Read temperature and heating status at any time
The room thermostat II 230 V shows the current room temperature and signals actions performed via the multicoloured LED strip.

Control your (underfloor) heating flexibly
You can control your underfloor heating on the device itself, fully automatically, via time programs or voice assistant and naturally via app while on the move.

Underfloor heating control via voice assistant
“Hey Google, make the living room warmer” / “Hey Alexa, increase the temperature in the living room by 1 degree”

You can control your smart thermostat for underfloor heating and other wired heating systems via voice commands too: It is compatible with the voice assistants Amazon Alexa and Google Assistant.

Achieve the optimum room temperature
The room thermostat II 230 V can be controlled via voice commands or the numerousother heating control options in the Bosch Smart Home app – or in the usual way using the rotary/push knob.

Practical: The LED matrix display lights up automatically and features a multicoloured LED strip to indicate actions performed. You can set the display brightness and switch-on time according to your requirements.

Measure and regulate humidity
The room thermostat II 230 V also measures the relative humidity in the room – and provides a visual warning if healthy limit values are exceeded. You can thus enjoy healthy room conditions and avoid mold.

The colourful LED strip on the thermostat’s display

• flashes blue as soon as the humidity exceeds 70 %
• flashes yellow as soon as the humidity falls below 30 %

If the values are normal, the display remains switched off and the LEDs will light up green if you turn the wheel.
