VAV Controller—Variable Air Volume (VAV) Controller 5
1 2FIntroduction
The Variable Air Volume (VAV) Controller is an electronic device for
digital control of single duct, dual duct, fan powered, and supply/exhaust
VAV box configurations. See 50HFigure 1. You may use the VAV as a
standalone controller or connected to the Metasys network through a
Network Control Module (NCM) or Companion system.
When connected to the Metasys Network, the VAV provides all point and
control information to the rest of the network. The devices communicate
through an N2 Bus.
Each VAV Controller application uses a different sequence of operation,
all of which are covered in the HVAC PRO for Windows User’s Manual
(FAN 637.5).
