LK 423 MiniLoop RTC is designed to control smaller under floor heating systems that are embedded in concrete or levelling compound 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 thermostat. It is also possible to install a wireless or wired electronic room temperature control.
