VVT Zone Controller 1What is a VVT Zone Controller?The VVT Zone Controller (#OPN-VVTZC), a component of the i-Vu Open Control System, controls zonetemperature in single duct, fan powered, Variable Volume and Temperature (VVT ® ) applications. The VVTZone Controller with built-in actuator maintains zone temperature by operating the terminal fan andregulating the flow of conditioned air into the space. Buildings with diverse loading conditions can besupported by controlling the air source heating and cooling sources or supplemental heat. The VVT ZoneController provides dedicated control functions for single duct and fan box terminals with modulating heat, upto 2 stages of ducted heat, or combination baseboard and ducted heat.The i-Vu Open Control System uses linkage to exchange data between the zone terminals and their air sourceto form a coordinated HVAC system. The system's air source controller, zone controllers, and bypass controllerare linked so that their data exchange can be managed by one zone controller configured as the VVT Master.The following illustration shows the VVT Zone Controller in a typical i-Vu Open Control System.VVT Zone(OP N-VVT ZC)VVT Zone(OP N-VVT ZC)VVT Zone(OP N-VVT ZC)VVT Zone(OP N-VVT ZC)VVT Bypass(OP N-VVT BP )MANUAL O N W AR MERO ccupiedINFO CO O LERFMANUAL O N W AR MERO ccupiedINFO CO O LERFMANUAL O N W AR MERO ccupiedINFO CO O LERFMANUAL O N W AR MERO ccupiedINFO CO O LERFIntroduction
