RTL control box for retrofitting individual rooms with radiant heating
The Kompabox RTL with connection option for a bathroom radiator is used to control the temperature of an underfloor heating, wall heating or ceiling heating in conjunction with conventional heating systems.
These systems require higher flow temperatures of up to 70°C and usually operate with conventional ribbed radiators or radiators made of sheet steel.
The Kompabox RTL includes additional connectors for bathroom radiator or heated towel rails, which can still be operated with the higher flow temperatures of the original heating systems
For a safe operation of the retrofitted underfloor heating, the RTL valve limits the return flow temperature to a maximum of 50°C. Thus, the RTL control box forms the connecting piece between the existing heating system and the underfloor heating. It regulates the temperature in retrofitted rooms such as bathrooms or kitchens completely independently of the existing heating system and ensures a maximum of heating comfort.
RTL - How it works
The temperature is regulated without additional auxiliary energy and can be easily adjusted individually using the supplied return temperature limiter head. It functions as a continuous proportional controller. The change in the indoor air temperature (controlled variable) is proportional to the change in the valve lift (manipulated variable). If the indoor air temperature rises, the temperature in the temperature sensor expands and acts on the corrugated pipe. This throttles or increases the water supply in the underfloor heating circuit by the valve spindle.
The RTL temperature control is a flush-mounted box with frame and fastening rails. A cover plate is included. The integrated supply shut-off means that heating areas can also be shut off individually.
The heating pipes of the existing system are connected to the 3/4" connections of the Kompabox with compression fittings. The FLEXIRO underfloor heating kit can be connected completely tool-free via a plugin-system. Installation dimension for the Kompabox in mm (H×W×D) 150×230×60.
