What is a VVT Zone II?
The VVT Zone II (#OPN-VVTZC-02), a component of the i-Vu® Control System, controls zone temperature in single
duct, fan powered, Variable Volume and Temperature (VVT®) applications.
NOTE
The VVT Zone II is available in both English or Metric units. The metric version has (-M) appended to the
part number. Everything in this document applies to both versions.
The VVT Zone II with 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 Zone II provides dedicated control functions for
single duct and fan box terminals with modulating heat, up to 3 stages of ducted heat, or combination baseboard
and ducted heat.
The i-Vu Control System uses linkage to exchange data between the zone terminals and their air source to form a
coordinated HVAC system. The system's air source controller, zone controllers, and bypass controller are linked so
that their data exchange can be managed by one zone controller configured as the VVT Master.
You can disconnect the actuator from the controller and mount them separately, connecting them with just the
actuator cable or using an additional extension cable, up to a maximum distance of 300 feet.
The following illustration shows the VVT Zone II in a typical i-Vu® Control System.
