Trying to model the Diakin 3mxl24rmvju in ResStock.

When I specify in options_lookup.tsv a [cfm/ton] min_cooling, max_cooling, min_heating, and max_heating airflow rate, should this be calculated using cfm and tonnage from the submittal/specs for the outdoor unit or the indoor unit(s)? The indoor unit(s) have lower cfm than the outdoor units across all fan speed settings (H, M, L).

Right now I calculate this using the cfm and tonnage (2-ton system) for the outdoor unit, but it gives me a cfm/ton that is a lot higher than comparable equipment in ResStock, which leads me to believe that I should be using the indoor unit cfm instead.

Airflow should be for the indoor unit.

Thanks! What if you have multiple indoor heads? Which submittal would you use? There are a bunch of different indoor units that can connect to the 3mxl24rmvju. Unsure which one I would use.
