Hello, I can't seem to figure out how to delete zone equipment under "Thermal Zones" . I've added baseboard heating but want to remove it.

I am using OS v1.10.

Thanks Phan

To delete ZoneHVAC objects using the GUI:

  1. Click on the zone equipment name

  2. Click the black/white X in the upper right corner of the inspector pane under the Edit sub-tab

To delete objects using the API or measure use the remove method.

# delete all objects
objs = model.getZoneHVACLowTempRadiantVarFlows

objs.each do |obj|

Is there any way to delete certain types of zone equipment such as only Zone HVAC Baseboard Rad Conv Water or fan coil unit but not air diffuser. And it will be great if users can specify zone name range to apply the deletion. This measure may save me a huge amount of time.

For ZoneHVAC objecst there's not really a way in the OS App, but it can be done using the code above with the API.

For AirTerminal objects click on the vertical branch to the right of the terminal image on the demand side of the Air Loop in the HVAC Systems tab and uncheck the zones you want to remove from the loop.
