The Climate Control Zoning System II for radiant floor heating systems has an auto-balancing feature that boasts faster reaction times and greater energy savings. According to Uponor, the technology calculates the energy need of single rooms and adapts the heat output of each loop by controlling the actuator’s on-and-off cycle, allowing the system to react to temperature changes faster and save energy. The system consists of a base unit ($350), an expansion module ($110), and digital ($115) or dial ($75) thermostats.
