just to double check, on your other heat pump run the aircon for a while then switch to fan (or heating), note the smell. is it the same as what your getting upstairs?

Na, because the upstairs (attic) aircon smells just like the attic in fan mode. Maybe not necessarily insulation smell, just smells like the attic as soon as I turn it on (New house, so probably treated wood, paint, insulation type of smell).
Well the system is performing much better on 100pa. My Dad, who works in commercial ducting installs, couldn't believe how the ducts bend too soon out of the unit. He thinks that would kill airflow considerably. Might be why I need high static pressure.
not sure. it would be nice to have it straight but there is space limits etc. your dealing with flex duct which is not as good as rigid. but imho its usually the grills and overall design thats the biggest. ideally use pressure/flow gauges to test to see where the restriction is.

if same smell in fan mode without running aircon for some time (so the coil isn't wet), then i would check the incoming side of the erv. i doubt its on the heatpump side because heatpump would suck it in all the time. first guess would be in-between the erv and prefilter.
