I have recently ventured into trying to implement using the system inspector, in order to determine teh pressure drop of the system. The problem is that it says that all of my components are set to preset or system, and that at least one needs to be set to calculated. The thing is that at least one component of each system is set to calculated.
For the VAV system, the air terminals are preset, the VAV outlet is set to calculated and the inlet is set to preset (All according to Kyle tutorial on his blog). Likewise for the air handler system, the outlet on the air handler is set to calculated.
So my question is what am I missing? According to the system inspector instructions things should be working. Any help would be greatly appreciated.
