Hello all.
I'm having difficulty reading the Differential setting. Can someone post a pic and explanation of where to read the dial for the indicated setting. I don't see a hash mark or arrow that indicates what number it's set to.
Thank you

    On my honewell there is a vertical black line (on brown box) right above the dial. Mine had wires in front of it that I had to bend out of the way in order to see the line.

    It's the white dial, visible when you remove the cover.

    Is it the brown box with the hot and neutral wires connected to it

    That brown box is the actual switch, you want the white dial to indicate 1 or just below closest to the front cover.

    My set up is slightly different. Here is a pic.
    This may explain why I can't figure where to line thing up.

    It looks to me like the number should be lined up under that medal tab (pointer) that covers the number. (Set at "3" now)

    That's what I figured as well, but it seems odd. Also, based on how I read what Dan has recommended that "3" seems way high(how I found it set when I first looked in the unit). The cut in is set at .5psi. So cut out would be 3.5 It's a 2.5 story private home. My rough calc. of the EDR would mean that the 3.5 is way high????????

    Set it to "1" so that the Cut-out is 1.5. The Empire State Building runs at 2 PSI. Turn it down. It will run fine.

    Also, on a different topic, there is a radiator on the second floor that recently started to make a sound while venting air. The best way I can describe it is, it sounds like someone is breathing through a slightly congested nostril while asleep. That is to say it's rhythmic, not steady, like a very soft whistling. Any thoughts??

    It's too high. Set "1" under that metal pointer, and the cut-in scale at its lowest.

    May have a little condensate in it. Take it off, wash it out and blow the water out of it. It may well not be clossing all the way due to dirt.
