Note: ‘Calibration mode is active’ occurs after an initial start-up sequence. In calibration,
the CCP automatically prepares the VariTrac system for operation by disabling heating
and cooling, closing the bypass damper, opening all zone dampers to their maximum
position and starting the fan. Calibration re-indexes the zones and bypass damper and
recalibrates the static pressure setpoint.
Reference: VariTrac Installation Manual (VAV-SVN03A-EN), page 44 for an explanation
