| String | id | dat.id | System tag |
| Boolean | have_souChiWat | | Set to true if system uses CHW |
| Boolean | have_souHeaWat | | Set to true if system uses HHW |
| Nominal condition |
| Modelica.Units.SI.MassFlowRate | mAir_flow_nominal | dat.mAir_flow_nominal | Discharge air mass flow rate |
| Modelica.Units.SI.MassFlowRate | mAirPri_flow_nominal | | Primary air mass flow rate |

| Dynamics › Conservation equations |
| Modelica.Fluid.Types.Dynamics | energyDynamics | Modelica.Fluid.Types.Dynamics.DynamicFreeInitial | Type of energy balance: dynamic (3 initialization options) or steady state |
| Assumptions |
| Boolean | allowFlowReversalAir | true | = true to allow flow reversal, false restricts to design direction - Air side |
| Boolean | allowFlowReversalLiq | true | = true to allow flow reversal, false restricts to design direction - CHW and HW side |
| Advanced › Diagnostics |
| Boolean | show_T | false | = true, if actual temperature at ports of subcomponents is computed |
