RTL combibox white floor heating system F11878

Kombibox RTL – Precise underfloor heating control

Kombibox RTL is a comprehensive solution for regulating thermal comfort in underfloor heating systems. The device combines the functions of return temperature limitation, setting, and flow shut-off, ensuring optimal operating conditions for the installation and energy efficiency. This is particularly important in mixed systems where underfloor heating works with traditional radiators.

Using Kombibox RTL allows for precise adjustment of the temperature in individual rooms, which translates to increased user comfort and reduced operating costs. Thanks to the integrated air vent, the device ensures trouble-free operation of the installation and eliminates the risk of disturbances caused by the presence of air.

Construction and application

Kombibox RTL consists of a wall box, a set of valves equipped with an air vent and a 3/4” GZ tapered thread, as well as an RTL Ro Therm I head. The device's design allows for installation in all types of walls with depth compensation up to 30 mm, which facilitates installation even in difficult conditions. Additionally, the ability to level the installation deviated from the vertical by up to 6° for each side provides flexibility during installation and an aesthetic appearance.

The device is intended for regulating underfloor heating, surface heating, and mixed radiator-underfloor heating systems in individual rooms. The RTL return temperature limiter acts as a proportional controller without auxiliary energy – it does not require additional electrical power. This makes it a reliable and energy-saving solution.
