The Climate Control Zoning System II from Uponor offers Autobalancing that boasts 25 percent faster reaction times and up to 20 percent greater energy savings for radiant floor heating systems. The technology calculates the actual energy need of single rooms and adapts the heat output of each radiant 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, completely removing the need for manual balancing of the system. The system consists of a base unit, an expansion module, and digital or dial thermostats. A single base unit can support up to six thermostats and eight actuators; adding an expansion module will increase those numbers to 12 and 14, respectively. 800-321-4739; www.uponorpro.com.
