## Long description

Afriso RTL-BOX 324 Vario is a radiator thermostat set designed for concealed installation to control radiator temperature reliably. The set comprises an RTL-type thermostatic valve and a flush-mounted cassette that allow limiting flow temperature and performing room-level regulation in heating systems. Its compact design makes it suitable where a discrete, built-in installation is preferred, for both new builds and renovation projects.
Advantages
The set provides precise flow temperature limiting with an RTL thermostatic valve matched to a flush-mounted box for neat, concealed mounting. Installation depth and alignment are engineered for standard radiator connections, reducing visible piping and improving interior aesthetics. Materials and construction ensure stable temperature control and compatibility with common heating system fluids. The modular design permits straightforward replacement of the functional valve insert without removing the cassette from the wall.
Suitable for
Concealed radiator installations in residential and commercial buildings
Renovations where existing radiators are retained but valve bodies are moved to a flush-mounted position
New-build heating systems requiring compact, hidden valve solutions
Applications that need flow temperature limiting to protect radiators and flooring
Key specifications
Type: RTL thermostatic valve with flush-mounted cassette for concealed installation
Function: Flow temperature limiting and room-level regulation for radiators
Installation: Flush-mounted (built-in) cassette for wall-concealed mounting
Compatibility: Designed for standard radiator connections and central heating systems
Design: Compact, modular assembly enabling valve insert replacement without cassette removal
How to use
Install the flush-mounted cassette into the prepared wall recess at the radiator connection point, ensuring correct alignment with the piping. Fit the RTL thermostatic valve insert into the cassette and connect to the radiator and supply pipe according to the heating system layout and local installation rules. Set the thermostatic control to the desired limiting temperature; the valve will regulate flow to maintain this limit while allowing normal room-level control. For service, remove the valve insert from the cassette without demolishing the wall-mounted box.
Usage recommendations
Use the Afriso RTL-BOX 324 Vario in systems with appropriate water quality and pressure as specified by the heating installer. Verify compatibility with radiator pipe dimensions and follow local norms for concealed installations. Periodic inspection of the valve insert during planned maintenance is advised to ensure continued temperature control performance.
