CTOT, APR, Auto Coarsen, and Condition Lever use

[Ecosse_821 24]

Hi All.  I am a new owner of this nifty little plane, and I've done a few flights with her and all has gone rather well.  I have the F1 GTN installed and working properly.

I'm wondering what the CTOT and APR settings are all about and what effect they have.

I also have no idea what the propeller setting "Auto Coarsen" is or does.

And regarding power management--I put the condition levers at full forward for takeoff.  Are these supposed to remain at this setting throughout the flight?  Is there anything I am supposed to do for climb power, or does everything pretty much stay at 100 percent until I have to descend (obvious that one must reduce power for descent and approach/landing).

Having a better understanding of the above items would increase immersion and make this fun little plane even more so.

 

Thanks!
