Hi everyone,

I have a problem a long time and I can not solve.

All VRF systems have the output with external air flow zero. I do not know what the problem is.

I used the example file VariableRefrigerantFlow_5Zone.idf, and even then the outside air is zero.

Does anyone know the source of the problem?

Thanks!
