    Hi all,

    I'm trying to debug a possible issue with my heater, possible air bubble...

    ok, here is my questions...

    Lets say my cabin temp is 70f
    I set my heater on auto to 75f
    Does that mean:
    #1. The air blowing out is 75f
    #2. The air blowing out is near 75, but it varies as it gets closer to 75

    In other words, is it blowing air temp or cabin temp?

    Just like at home, it's a setting for what you'd like the cabin temp to be.

    If the cabin temp is below that, the system will try to bring it up by blowing air that's warmer. If the cabin temp is above, it will blow air that's cooler. How much warmer or cooler depends on a lot of things, including how different the cabin temp is from what you set. Some formulas it uses are given in the manual (at least they are for my gen 1 model, I assume they are for yours too).
