Default AUX Input for IAT compensation

Hello Richard,

Can you please tell me a bit more regarding the AUX Input feature which allows for IAT compensation? I read somewhere in this forum about it but I just want to know a bit more.

So this 0-5v signal is non adjustable and is automatically done by the HFS4 to deliver -5% of wmi when it is 0v and +5% when it is 5v?

What if the IAT sensor is hottest when is 0v and coolest when is 5v? Can the signal be inverted?
