LK 423 MiniLoop RTC

• Small and compact

• Suitable for areas up to 10 m2

LK 423 MiniLoop RTC is designed to control smaller under floor

heating systems that are embedded in concrete or levelling com-

pound with a pipe dimension of 8 mm, 12 mm, 16 mm or 20 mm.

LK 423 MiniLoop RTC has integrated return temperature limiter

that make it possible to limit the floor surface temperature.

The room temperature is regulated via a capillary tube thermo-

stat. It is also possible to install a wireless or wired electronic

room temperature control.
