Connection Kit Varioterm RTL LimitBox ZKZRTL06/K with white cover

Connection kit Varioterm RTL LimitBox ZKZRTL06/K with white cover is a compact assembly intended for installation of an RTL (return temperature limiter) unit within heating circuits. The kit contains the necessary components to mount and connect the RTL device behind a protective, white plastic cover, providing a tidy and accessible installation point on radiator or manifold lines. It is designed to integrate with residential and light-commercial heating systems where control of return temperature is required to protect radiators and ensure efficient system operation.

Advantages

The Varioterm RTL LimitBox kit keeps the RTL unit concealed yet accessible for service, limiting exposure to mechanical damage and accidental tampering. The included white cover provides a uniform finish that blends with typical interior installations while offering protection against dust and debris. The kit simplifies on-site work by grouping mounting and connection parts into a single package, saving time during installation and maintenance.

Suitable for

• Installation of a return temperature limiter (RTL) on radiator circuits
• Retrofit projects where a compact covered connection point is required
• Residential and light-commercial heating systems
• Professional installation and maintenance tasks

Key specifications

• Scope: connection kit for RTL installation with protective cover
