Parameter configuration for use case 5a:
• VavSuChovrCnd1 = Cooling
• VavSuChovrCnd2 = Heating
• VntDuctSprt = Both ducts
• CtlStrgy = Mixing control
• VntSprtDdband = Duct 1 (mixing will occur at/during setpoint for Duct 2 hot duct)
• Minimum ventilation parameter(s)* = desired CV flow
*In the room AF for ventilation control (VavVntCtl) set min vent parameter for Comfort mode (AirFlMinRCmf) to
desired CV flow; the min vent setpoint object in VavSuDuald11 (VavSuAflMinVnt) can be set to zero when the
minimum ventilation parameters are used for min vent settings.
Note that if minimum ventilation parameter is not set high (for example during Economy mode) constant vol-
