I am having trouble getting this little bit of code to work:
# Make a new fan and coils
vav_fan = OpenStudio::Model::FanVariableVolume.new(model, model.alwaysOnDiscreteSchedule)
new_cooling_coil = OpenStudio::Model::CoilCoolingDXMultiSpeed.new(model)
new_heating_coil = OpenStudio::Model::CoilHeatingDXMultiSpeed.new(model)
new_supheating_coil = OpenStudio::Model::CoilHeatingElectric.new(model)
# Make a new AirLoopHVAC:UnitarySystem object
runner.registerInitialCondition("Line 212")
air_loop_hvac_unitary_system_multi = OpenStudio::Model::AirLoopHVACUnitaryHeatPumpAirToAirMultiSpeed.new(model, vav_fan, new_heating_coil, new_cooling_coil, new_supheating_coil)
# Add the VAV fan to the AirLoopHVAC:UnitarySystem object
air_loop_hvac_unitary_system_multi.setSupplyAirFan(vav_fan)
# Set the AirLoopHVAC:UnitarySystem fan placement
air_loop_hvac_unitary_system_multi.setSupplyAirFanPlacement('BlowThrough')
# Set the AirLoopHVAC:UnitarySystem Supply Air Fan Operating Mode Schedule
air_loop_hvac_unitary_system_multi.setSupplyAirFanOperatingModeSchedule(model.alwaysOnDiscreteSchedule)
runner.registerInitialCondition("Line 214")
I get this error telling me that the new object does not have a supply fan attached:
[openstudio.model.AirLoopHVACUnitaryHeatPumpAirToAirMultiSpeed] Object of type 'OS:AirLoopHVAC:UnitaryHeatPump:AirToAir:MultiSpeed' and named 'Air Loop HVAC Unitary Heat Pump Air To Air Multi Speed 1' does not have an Supply Air Fan attached.
