DHC.Plants.Combined.Controls.BaseClasses.ModeCondenserLoophas instances likeReal fraChaTanIns(final unit=“1”)=..... It’s not allowed by CDL. We may need to develop a subsequence to avoid that.DHC.Plants.Combined.Controls.BaseClasses.ModeHeatRecoveryChiller, it has the algorithm section. It’s not allowed by CDL.DHC.Plants.Combined.Controls.BaseClasses.StageIndex,DHC.Plants.Cooling.Controls.ChillerStageandDHC.Plants.Cooling.Controls.FlowControluse state machine. The blocks should be specified as an extension block?DHC.Plants.Combined.Controls.BaseClasses.StagingPlant, theRealExpressioninstantiated block has the output asabs(PLRStaTra*(min(nChi, max(0, staCoo.preIdxSta - 1))/nChi*QChiWatChi_flow_nominal + max(0, staCoo.preIdxSta - 1 - nChi)/nChiHea* QChiWatCasCoo_flow_nominal))). The calculation should be implemented in a separate subsequence.DHC.Plants.Combined.Controls.BaseClasses.TankCycle, it hasinitial equationsection.DHC.Plants.Combined.Controls.BaseClasses.ValveCondenserEvaporator, it instantiatesIntegreExpression, which refers output from other blocks.DHC.Plants.Cooling.Controls.ChilledWaterPumpSpeed, it has an instance that instantiates classBuildings.Applications.BaseClasses.Controls.VariableSpeedPumpStage, which is from packageBuildings.Applications.
