The Function set-up provides quick and easy access to all
parameters required for the majority of VLT HVAC Drive
applications including most VAV and CAV supply and return
fans, cooling tower fans, Primary, Secondary and Condenser
Water Pumps and other pump, fan and compressor
applications. Amongst other features it also includes
parameters for selecting which variables to display on the
LCP, digital preset speeds, scaling of analog references,
closed loop single zone and multi-zone applications and
specific functions related to Fans, Pumps and Compressors.
The Quick Menu parameters can be accessed immediately
unless a password has been created via 0-60 Main Menu
