Get full control over your indoor climate and maximize energy efficiency with intelligent LK actuators and control components at Velltra. For an underfloor heating system to deliver perfectly balanced heat in all rooms of the property, precise and automated control is required. LK's advanced actuators are mounted directly on the underfloor heating manifold and are controlled wirelessly or wired by room thermostats to open and close the flow to the different loops. This ensures that the right temperature is maintained exactly when and where it is needed. Explore our range of type-approved actuators, thermostats and control centers for smarter heating control.
