The VVT Zone Controller with built-in actuator maintains zone temperature by operating the terminal fan and regulating the flow of conditioned air into the space. Buildings with diverse loading conditions can be supported by controlling the air source heating and cooling sources or supplemental heat. The VVT ZoneFile Size: 1MBPage Count: 80
