Underfloor heating controller

Make your underfloor heating smart without much effort and enjoy automated control as desired. To do this, simply install the underfloor heating controller.

Cosy warm floors with individual heating profiles.

Stepping barefoot onto the warm floor in the bathroom directly after getting up - a wonderful feeling, especially in winter. Control and regulate your underfloor heating the smart way and individually: With the underfloor heating actuator from Homematic IP. No new cables are needed to install it. You heat comfortably as you wish: With six adjustable heating profiles and 13 changes per day.


Comfort temperature at any time

Control the room temperature according to your needs - at home and when you're out and about.


You can do this easily via the app, directly on the device using the dial or conveniently via
voice control (using Amazon Alexa or Google Assistant).


The easy way to save heating costs

You can easily set the individual temperature profiles in the Homematic IP app.


To ensure that the heating is only on when you want it on, there are up to six adjustable heating profiles (three for heating and three for cooling) and 13 possible changes per day.

Easy installation

You don't need to lay any more cables, as the actuator communicates via radio. Install the underfloor heating actuator either on the wall or on DIN-rails using the screws provided.


Flexible control possibilities

Use the underfloor heating actuator by itself in stand-alone operation or as part of your smart home. You can control up to 10 heating zones with one actuator.

  • A wall thermostat (HmIP-WTH-B) is required for stand-alone operation. However, the actuator does not need an access point or an app. You make the settings directly on the wall thermostat.
  • As part of a Smart Home system, in addition to the actuator you need the Homematic IP access point: Operation and adjustment are simple via the free app. You can expand your smart home flexibly in many areas just as you wish.

Heating or cooling? You choose

If you'd like to cool your floor as well as heat it, simply add a Multi IO Box to the underfloor heating actuator.


The Multi IO Box controls a heating boiler or heat pump with which you can also use the underfloor heating for cooling.

Homematic IP means modern, flexible and secure technology from the European market leader*. Let the advantages of our system win you over, and start living smarter straight away. 

With some smart home providers, you have to make a choice: Do you have everything wired, or do you go fully wireless? Some systems are also hermetically sealed and do not accept devices from other manufacturers. Here at Homematic IP, we have a different approach. We are guided by you!

The Homematic IP app

Configure all the settings for your smart home in the Homematic IP app, and use it to control, regulate and monitor your devices whenever you want – without providing any personal data!
A smart home system is particularly robust, interference-proof and reliable when the devices communicate with each other via wired connections. And data transmission is very fast with cables, too. That all comes together with Homematic IP Wired.
