Atom x /erg mode

Hi everyone this has probably been asked hundred times I just got an atomx all seem to be going good I can see that all I have is erg mode so my question is if I was going to do 20min test would it know to turn erg off or what way would that work ? Thanks

I have a first gen Atom. I don’t think you can turn off ERG mode on a Wattbike with Trainerroad.

I’ve also got a Gen 1, I’ve always done the FTP test using the hub, that way you can use gear mode or ERG.

However, why bother with either? TR will just tell you your FTP.
