From the manufacturer

Measure temperature

The thermostat measures the temperature where it has been placed and transmits it to the radiator thermostats for more precise and efficient control.

Read temperature and status

The Room Thermostat II shows the current room temperature all the time and intuitively signals actions performed via the stylish LED colored strip.

Portable or wall-mounted

You can position the Room Thermostat II wherever you want or mount it on a wall (wireless installation with supplied accessories).

Measure the humidity

In addition to the temperature, the thermostat measures relative humidity – and provides a visual warning as soon as set limit values are exceeded.

In winter and in summer

Achieve your desired temperature even more precisely and efficiently

The Room Thermostat II ensures the temperatures you want in summer and in winter: It is not only a remote sensor for your radiator thermostats – it can also connect to other smart devices (via the Bosch Smart Home Controller) to automate shutters or fans during hot weather in summer for example.

As a result, you can achieve your desired temperature to the nearest half a degree effortlessly and precisely.

More than just a thermostat

Keep track of the humidity for healthy room conditions

By measuring the relative humidity as well, the Room Thermostat II helps you to maintain healthy conditions in the room and avoid mold. The colorful LED strip on the thermostat’s display flashes blue as soon as the humidity exceeds 70 % or yellow as soon as it falls below 30 %. If the humidity values are in the normal, healthy range, the display is switched off per se and the LEDs will only light up green if you press the button.

Automate humidifiers/dehumidifiers

To keep humidity within a healthy range automatically, you can switch on a humidifier connected via a smart plug compact using an automation for example as soon as the humidity falls below 30 %.

Smart heat protection: Automate shading

The Room Thermostat II is practical not only for heating. With the help of an automation, it can also lower shutters automatically to keep out the heat when it measures temperatures above 25 degrees.

Can also be combined with Radiator thermostat I

The Room Thermostat II is designed for use with the Radiator Thermostat II. However, it can also be used with the Radiator Thermostat I with limitations (only remote control and temperature display).

Precise heat regulation: Controls smart radiator thermostats in a room so that your desired temperature is achieved where the room thermostat is positioned.
Keep track of the temperature: Thermostat shows the current room temperature, heating status and relative humidity on an LED matrix display
Flexible use: Thanks to the mounting bracket and its wireless design, the room thermostat can be positioned anywhere in a room or mounted on a wall for use as a wall thermostat
Convenient control: Heating can be adjusted on the device itself using a rotary/push knob or via the app from a remote location
Maximum added value: You need a Bosch Smart Home Controller to integrate the device into your Bosch Smart Home system
Package contents: 3x Room Thermostat II, 12x AAA batteries, 3x wall mounting set, 3x mounting bracket, quick start guide (11 languages)
