Cockpit temps

It's gonna be a cold winter flying this aircraft!!! Doesn't matter what you do with the temp system. it keeps going down (cold)-4!!!! I don't think this system works very good.

@mobbe123 Have you switched the bleed air to high?

From the manual: "During high altitude flight, the “AUTO” bleed air setting may be insufficient to heat the cabin to a comfortable level. If this occurs, the bleed air switch may be placed in the “HI” position for additional heating."

@pixel-of-life Yep did all that. Even sitting on tarmac long enough in cold weather and the position on high, the temp still goes down.

Did you turn the AC off and just run the fan?

@mobbe123 this works for me:

• bleed switch: auto
• air cond: fan only (or ON if you also require cooling)
• cabin temp selector: 20 (or 11 o'clock position)
• defog/normal: normal (all the way right)
• emergency ram air pull handle: pushed fully in
• (obviously) all doors and windows closed :)

With this I can keep comfortable 20 deg C in -20 outside temp at high altitudes.

Also check if the aircraft is able to pressurize, maybe you have a leak somewhere.
And check the WXR page for any related failures :)

@randolf Yep It was the fan that was my problem. I didn't use as I thought it was something to do with AC only. Works pretty good now.
Thanks!
