I'm wondering if I'm doing something wrong on the cabin temp control on the Duke.  I'm flying at FL260 with an OAT of -30C.  I have the cabin temp mode set to Auto Heat, vent blower on high and the desired setpoint for cabin temp at 75F.  However, the cabin temp is slowly falling and is currently in the mid 40's F.

Am I doing something wrong or is the heater just not able to keep up at these flight levels and OAT's?

You have to pull out the white knobs below the copilot yoke (above the red pressurization handles).  They're marked pressurization Air Temp pull to increase.  Pull them all the way out, keep the heat to auto, temp dial 12 o'clock is fine.

As you get back down to lower altitudes, you need to close them back up or they can melt the duct work.

I find this kind of management fun and adds immersion. Can always ignore it if one wishes, or tweak it to make our virtual pilot "comfortable".

Wish there was an add on that could optonally make the screen a red tint when the pilot "feels" warm, redder the tint, hotter the pilot; and a blue tint for cold. 

Thanks for the reply Orlaam, I'll give it a shot on my next flight.  I also really like the immersion that this sort of thing adds to every flight.

Curious if I forget to close the knobs and melt the ductwork (which I will for sure forget one time at least) is an actual failure triggered that we'd see?

The cabin air system can fail, but I'm unsure if it'll detect temperature exceedance to trigger that failure.  I just know the manual mentions AC and heat system failures.
