Frequently asked questions on radiator thermostat

How can I attach the Bosch Smart Home Radiator Thermostat?

Explanation of how to attach the radiator thermostat

The Bosch Smart Home Radiator Thermostat can be attached to nearly all radiators. To do so, simply remove your old thermostat and attach the Bosch radiator thermostat. A few radiators require a special adapter which is included with the accessories for your radiator thermostat. For a step-by-step installation guide, follow the instructions in the app or the installation manual supplied.

The Bosch Smart Home Radiator Thermostat does not fit on my radiator.

Thermostat adaptation to radiator

If the Bosch Smart Home Radiator Thermostat does not fit onto your radiator, it may be necessary to use one of the enclosed adapters.

The thermostat does not go into setback mode when a window is opened.

Connect with the door/window contact

Open the door/window contact and wait a few seconds. If the room still does not switch into setback mode, it may be for various reasons:
1. Check whether the window contact is indicating opening and closing on the built-in LED. Furthermore, the window contact of the respective window must be assigned to the same room as the thermostat
2. The window contact components must not be mounted more than 8 mm away from each other and must be at the same height (lower edge) so they can find each other.
3. The batteries in the window contact and thermostat must be inserted correctly.
4. Please check whether two or three LEDs light up white continuously on your Smart Home Controller,depending on whether or not remote access is activated.
