Introducing Roth Touchline® SL
The Roth Touchline® SL is a next-generation wireless control system that’s designed for comfort, convenience, and energy efficiency. Built to meet the demands of modern homes and lifestyles, it offers intuitive, individual control over your underfloor heating and radiator zones.
It’s fully wireless, making it ideal for both new builds and retrofit projects, and supports up to 48 independent heating zones – so you can fine-tune temperatures to suit every space.
Green Flare trusts Roth Touchline® SL not only for its performance, but for its smart home compatibility, sleek thermostats, and seamless integration with the high-quality Roth systems we already install.
Easy-to-Use, Intelligent Controls
What makes the Roth Touchline® SL system different are its intuitive, wireless room thermostats – available in a range of styles to suit different spaces and preferences. These thermostats allow for precise, room-by-room temperature control, helping you maintain comfort where you need it, and save energy where you don’t.
Choose from models with infrared floor sensors for accurate surface temperature regulation, or versions with humidity sensors – ideal when your system includes cooling functionality. All thermostats feature a clear display and simple interface, making it easy to adjust settings with a tap.
For larger spaces or open-plan layouts, multiple heating loops can be grouped under a single thermostat, giving you powerful control without complication.
As the system is fully wireless, it’s also ideal for upgrades and retrofits. There’s no need to chase cables into walls or disturb finished floors, making installation quicker and cleaner.
Control Anytime, Anywhere with the Roth App
With the Roth Touchline® SL app, you can manage your underfloor heating from anywhere – whether you're at home, at work, or away for the weekend. The system connects to your WiFi through the compact Roth SL module, giving you remote access to every zone in your home.
Using the app, you can:
-
Adjust room temperatures on the go
-
Set and change heating schedules
-
Monitor system status and receive alerts
-
Control multiple homes or zones from one account
-
View useful data like temperature trends and system activity
The app also supports voice control via Google Home and Amazon Alexa, letting you adjust your heating with simple voice commands.
With smart features like weather-based regulation and automated mode switching, Roth Touchline® SL doesn’t just respond to your settings – it adapts to your lifestyle.
Built for Energy Efficiency
The Roth Touchline® SL system is designed to do more than just heat your home – it helps you use energy more intelligently. From reducing unnecessary heat loss to optimising when and how your system runs, it gives you more control over your energy usage.
With ECO inputs, the system can automatically switch between heating and cooling based on signals from your heat pump or external systems – ensuring you never use more energy than you need. And if you’re on a time-of-use energy tariff, Touchline® SL supports load shifting, allowing you to store or delay heating until electricity is at its cheapest.
Window contact sensors offer another smart touch – automatically pausing heating in a room when a window is opened, helping to reduce waste and cost.
You can also set temperature limits per zone, helping to avoid overheating and keep each space within comfortable, efficient boundaries.
