BOSCH SMART HOME - Thermostat Zigbee the radiator intelligent II

Heat while saving energy

The Smart Home radiator thermostat makes saving energy simple: thanks to time programs and intelligent services such as "Sustainable Ventilation", you heat your rooms only as comfortably as you need them.

Group thermostats to ensure room temperature

Several intelligent thermostats in the same room can be connected and controlled together directly from the app to ensure a room temperature, which can also be guaranteed particularly precisely by a room thermostat.

Flexible use

The intelligent Radiator Thermostat II can be used with all the features of the Bosch Smart Home system, or with the current Zigbee* standard.

You can decide how to use the device and what's best for your individual configuration, even after purchase. You can switch between the Bosch Smart Home system and your preferred Zigbee system at any time. So you always have a free choice of use!

*Information on integration and use is provided by the relevant supplier.

Sustainable ventilation and temperature reduction

Windows open, heating off - automatically! With the "Sustainable ventilation" service, you don't heat through the window: if your door/window contact detects that a window is open, it automatically reduces the temperature of the intelligent radiator thermostats. You can set the throttling reaction time yourself, so that it doesn't trigger every time a window is opened.

Detecting a drop in temperature: in addition, your smart thermostats can detect a sudden drop in room temperature and react with a heating pause and/or a push message.

Thanks to services like these, intelligent heating can save up to 36% energy.

Identify heating status with a color code

Connecting to your Smart Home system isn't the only feature that makes your radiator thermostat smart: its design also stands out from traditional devices.

Thanks to its compact size of 87 x 51 x 51 mm (L x W x D) and its rotating display, it fits discreetly into your home, after being mounted either horizontally or vertically, as you wish.

The high-contrast, backlit display guarantees optimum legibility, whatever the lighting conditions.

Practical: the fully illuminated ring with multi-colored LEDs also provides a clear indication of actions performed and thermostat status.

Activate child safety

When children innocently touch radiator thermostats, they quickly upset them and you waste energy. Avoid this kind of inconvenience and the temperature variations that go with it.

By locking manual settings directly on the appliance using the app or the button on the thermostat itself.

In this way, children will no longer be able to change the settings on smart thermostats, and you can continue to comfortably set the room temperature from the app, voice assistant or room thermostat.

Rely on protection functions

Have you ever been literally "caught cold" by a heating failure? Not with Smart Home! Your radiator thermostats help you limit the risk of a breakdown thanks to several protection functions:

• Frost protection: prevents damage to radiators caused by opening windows or leaving rooms unoccupied.
• Anti-scale protection: to prevent your thermostats from scaling outside the heating season, the valve opens briefly once a week throughout the year.
• Battery status warning: if the two AA batteries are running low, you'll be informed directly by the application several weeks in advance, so you can replace them in good time.
• Breakdown warning: want to get away safely? Create an additional automation program "IF room temperature < 15° THEN send message".

Installation made easy

You don't need to be a heating professional to make your radiator thermostats smart.

Bosch Smart Home thermostats can be installed quickly and easily without the help of an installer. The step-by-step instructions in the application guide you through the installation process. And thanks to the 2 AA batteries included in the delivery, your thermostat is immediately ready for use.

By the way, smart thermostats can be fitted to almost any radiator: either directly with M30 (1.5 mm) threads, or using the adapters supplied (Danfoss RA, Danfoss RAVL). Our test service will tell you if you need an adapter.
