I am a bit confused with this **** and the dots in between, I toggle back and forth from the main highlighted settings but don't see the difference. The manual mentions it is a mixture of the two modes and this is where I get lost. Can someone tell me what these dots signify?

 

Blue=cold. Red=Hot. Depending upon where you them dtermines the mix.

 

Helm, your guess is correct.

Basically the dot positions between the marked directions are intermediate steps.

So dots between "Forward Venting" going towards "Forward and Downward Venting" will increase the amount of downward venting as it approaches the "Forward and Downward Venting" position and vice versa.
