Uponor’s Climate Control Zoning System II features auto-balancing technology for residential hydronic radiant floor heating systems. The technology calculates the actual energy need of single rooms and adapts the heat output of each loop by controlling the actuator’s on and off cycle. This technology allows the system to react to temperature changes faster and offers greater energy savings in the process. The complete system offering consists of a base unit, an expansion module and digital or dial thermostats. A single base unit in the system can support up to six thermostats and eight actuators. Adding an expansion module will increase the number to 12 and 14, respectively.
