Boost key for quick heating
The boost function of the Homematic IP Radiator Thermostats ensures a quick and cosy feeling of warmth in the room. With just a press of a button the radiator valve is fully opened so that the room is heated up in a minimum of time.
Activation of the boost function is so easy: either directly at the thermostat at the push of a button or via the intuitive Homematic IP App. This means that the function can be conveniently started at any time, even when you are out and want it to be warm when you get home. After the set time, the system switches back automatically to the normal heating mode.

Whether it's the intelligent control of your heating, the security of your home or convenient lighting control – discover the versatility and efficiency of the Homematic IP devices working together to make your everyday life easier in our examples.
Heat intelligently, cut costs: Intelligent control system for up to 33% energy savings
With the intelligent combination of radiator thermostat, wall thermostat and window and door contact, you can not just enjoy maximum comfort, but also energy savings of up to 33%. The wall thermostat ensures precision control of the room temperature and communicates directly with the radiator thermostat, which adjusts the heating output as needed.
More
As soon as the window and door contact detects an open door or window, it immediately informs the radiator thermostat, which then reduces the heating output. This prevents unnecessary energy consumption and saves you money – simply and effectively with Homematic IP.

Boost function
Quick heat at the push of a button
The boost function ensures quick heating of the room. At the push of a button, the heat output is briefly maximised so that the room is pleasantly warm within minutes. This function is particularly useful if you want to switch quickly from cold temperatures to a pleasant room temperature.
Open-window detection
Greater efficiency through smart “open-window” detection
Open-window detection prevents energy from being wasted by automatically reducing the heating output when a window is opened. In combination with Homematic IP Window and Door Contacts, this function can be controlled with even more precision for further savings in energy.
Eco mode
Eco mode reduces your heating costs
Eco mode is an energy-saving function that automatically reduces the room temperature to save heating costs. This is particularly useful if the room is not used for a longer period of time. Eco mode helps to reduce energy consumption without compromising comfort.
Whisper mode
Silent heating for maximum comfort
The whisper mode of our radiator thermostats ensures particularly quiet temperature control that you can barely hear. Ideal for bedrooms and children's rooms, this mode allows you to adjust the heating output almost silently so that you can live in peace and comfort at all times. Enjoy the perfect combination of efficiency and silence without any disturbing noises.
Holiday mode
Relax while travelling with the smart holiday mode
The Homematic IP Radiator Thermostat holiday mode is the ideal solution for saving energy while you are away. Reducing the room temperature to a minimum prevents unnecessary heating when nobody is at home. At the same time, this mode protects your heating system from frost damage. Come home to a well-protected and energy-efficient house without having to worry about the heating.
FAQs – your questions, our answers
In our FAQs you will find the answers to the most frequently asked questions – in compact and comprehensible form and always to the point. Find out all you need to know for optimum control of your smart home!
How does window open detection work with Homematic IP radiator thermostats?
Window open detection works in combination with Homematic IP window and door contacts. As soon as the contact registers that a window is open, it sends a signal to the radiator thermostat. This then automatically reduces the heating output to save energy while the window is open. Without the window and door contact, detection is triggered by a sudden drop in temperature in the room, whereupon the thermostat also reduces the heating output.
Can water escape when replacing a Homematic IP radiator thermostat?
No, when replacing Homematic IP radiator thermostats, no water can escape from the radiator. The thermostat only controls the opening and closing of the valve and does not intervene in the heating system. As long as the valve itself is intact and remains closed, there is no risk of water escaping. The thermostat can be installed and removed safely and dry without having to drain the heating water.
What do the climate control operating modes do?
Your Homematic IP climate control solution offers five operating modes:
- In automatic mode, the system controls the temperature according to the heating schedules you have defined and selected.
- In manual mode, you can manually regulate the room temperature independently of the heating schedules.
- In eco mode, which can be activated via the home screen on the app or via the Homematic IP Wall-Mount Remote Control, all or any rooms equipped with radiators or electric heaters are automatically lowered to a predefined eco temperature (reduction temperature), for example after pressing the wall-mount remote control when leaving the house.
- In party mode, you can maintain the room temperature at a certain temperature value for a precisely defined period of time.
- In holiday mode, you can lower the room temperature to a freely selectable temperature value until a time you define if you are going to be away for any length of time. In holiday mode, the temperature of the floor heating system is also lowered.
