Aha. Two separate air flow systems. The diagram clearly show that the fans pulls ambient air through the evaporator in a cooling loop, regulated by thermostatic valves. The second loop is for the generated hot air, flowing through a mixing ejector. It is a fairly simple, but robust system and it makes perfect sense now. Thank you for the reference to the pilot handbook. Cheers!

Thanks for your comment. Interesting graph, will also do more testing during the weekend and post some curves. In my described scenario I had -19 deg. C in cockpit and had the AC in auto as usual when fiddling with the flight planner. After the G1000 hacking were done I registered the cabin temp had risen to +10C, and since the 'pilot' still had 'blue' vision due to frost, i tried to boost the cabin temp in manual mode. But alas, any fan setting, other than "off", made the temperature plummet. Turning AC to auto made the temperature rise at a steady rate - similar to when AC in manual had the fan turned off. Found this to be a bit strange, but I've never been in a TBM in the Arctic before.

Ref. Quick start guide 4.11 Environmental Control System Airframe located in ambient temperature of -20 deg C. Temp knob set to max. Door closed, idle flight mode. Cabin temp at -19 when AC set to manual mode. Bleed in auto. Hot air flow in mid position. Pres mode auto, dump in norm. When AC in manual, cabin temperature increase when fan speed is set to off - and decrease if fan speed set to 1 through 4 - decreasing faster at setting 4. When AC set to auto, cabin temp increase.

Oh dear. ATIS, by bad. Thanks, will include Log.txt when it occur again. Should it be posted here or to an email address (would prefer that). Let me thank you for an amazing experience so far with the TBM900. Absolutely a gem!
