IMI Eclipse radiator valves

I’m looking at fitting these on all the radiators in my house. Looking at the settings guide it all seems straightforward. The problem is all my radiators are aluminium. I have been on the Honeywell app for their auto balancing valves (They have settings for aluminium radiators)
When you enter the size of radiators in aluminium it comes out a totally different setting than if you enter the known heat load of the radiator.
The settings I get for one of the aluminium radiators if I input the aluminium radiator settings I get preset 2.5, 39 l/h
The settings I get for the same radiator under known heat load setting on the App is preset 4.5. 85 l/h
How do I know what settings to use if I get the IMI valves? They have no presets for aluminium radiators.
Cheers for any help..
