Afriso single-room control RTL-Box 324 Vario with return temperature limitation

- Very compact inspection plate (11.5 x 13.5 cm) made of high-gloss plastic
- Attractively shaped compact control head
- Precise alignment with the installation wall thanks to the depth-adjustable installation frame
- Aesthetic design allows for user-friendly placement at light switch height

Application:
For decentralized temperature control of individual rooms with floor or wall heating systems in combination with a radiator installation. Ideally suited for situations without radiator installation and without the desire for a central distribution. The RTL-Box 324 Vario combines heating circuit, room sensor and control in one. The purely mechanical functioning of the room control requires no additional electrical energy for actuators or similar. Thanks to its compact dimensions and aesthetic design, the RTL-Box fits perfectly at the same height as light switch installations. This ensures optimal control properties and increased user-friendliness. Description: The RTL-Box 324 Vario single-room control system consists of a high-quality, high-gloss cover plate made of robust plastic, an attractively designed thermostat control head and a mounting frame. The installation frame adapts ideally to the wall conditions and compensates for a wall height of up to 25 mm. The optional extension set extends the thermostat head by 20 mm if the wall structure exceeds the maximum wall height. The wall installation box with protection against tampering includes a pre-settable valve assembly consisting of a control valve, a thermostat valve and a return temperature limiter for limiting the radiator return temperature to a suitable temperature level for the underfloor heating. The valve opens when the temperature falls below the set limit. The pipes of the underfloor heating system are fixed in the wall-mounted box using standard compression fittings.
