Caleffi’s 171 and 172 Series manifold mixing stations regulate a system’s fluid temperature and are specifically designed for use in manifold-based hydronic distribution systems. The 171 Series motorized manifold mixing station incorporates a modulating three-point floating actuator to regulate the temperature of fluid sent to the system flow manifold, according to the actual thermal load, in response to a separately sourced outdoor reset controller. The 172 Series thermostatic manifold mixing station maintains the flow temperature at a constant set value for use in low-temperate systems such as radiant floor panels.
