LK 120 SmartComfort valve rotary actuating controls are unique electronic indoor temperature controllers for use in hydronic heating applications. Uniquely, the actuator and controls are built into a single Rubik's Cube sized housing (about 2 1/2") that mounts to the stem of LK mixing valves. Applications include temperature control of under floor heating, radiant panels, baseboard heating, and other forced hot water residential or commercial temperature control applications. It is possible to control individual zones or entire manifolds. By measuring supply and indoor temperatures, the LK 120 SmartComfort regulates the mixing valve to provide the system with the exact amount of heat required at any given time. (read more here)
