HB Thermal Load Balance Error “Need more than 4 values to unpack”

Hi,
I am trying to go do HB Thermal Load Balance but I am getting an error - “1. Solution exception:need more than 4 values to unpack”. When I input value from HB read room energy.

Can someone please help?

Hi found a similar query in the forum but that also didn’t help. “LoadBalance Error "Need more than 4 values to unpack"

I have attached the image, Internalised the geometry, and kindly update the epw file if needed. The epw file is big to be uploaded.

Hi everyone,
I have the same problem which the newest version of Ladybug can someone please help? Pranav did you find a solution?

Not all the geometry was internalized, but in order to get the fae_energy_flow output you need to include the sim_outputs and sim_par definitions, like so:

thank you for your reply Abraham, sadly I have an issue with the HB thermal load balance.

The error code is: 1.Solution exception:need more than 4 values to unpack

I used the HVAC Ideal Air and I am currently on 1.8.1. When using on 1.8.0 the script ran perfectly fine. Any idea on what the issue could be here ? Thanks a lot in advance.

Without the script it’s hard to say and help.

I would be happy to send it to you,but it says new users cant upload documents? How can i upload it ?

Thank you.

You can post a link to download it.

Sure thing here you go:

update as of the ladybug tools with 1.8.0 this script is working with 1.8.1 components only the load balance is causing an issue.

Next time please send a simplified version of the script.
I filtered the model to just simulate one of the floors.
See the red marks. You need to set the outputs to true, you need to connect the necessary outputs to the balance component.
After that is runs fine on my computer.
