Climate Ready® Zone Intelligence Unit (CR-ZIU) CR-ZIU is a user centred zone control system that offers intelligent comfort options. It incorporates the sopisticated ZIOS - Zone Intelligence Operation System - powered by Enigma. Enigma explained
Enigma acts like a brain. It is similar to a central nervous system that senses changing comfort factors and requests.
