Please help fill in fields 3F,G,H and 4D,E,F, in red xxx

    Page 21 at http://johnstonesupply9.com/TechDocs...13%20Specs.pdf does not list the variable speed air handler matchup for AVPTC1830 to the condensing unit GSZ13024B (GSZ130241B?)

    Easy to see why you are having trouble. This is a pro job. It is a lot easier on paper because you can mark it up and make notes on paper to keep your thinking clear.

    The expanded cooling data for the GSZ130241B pages 6 and 7 likewise lists no matchup to the air handler AVPTC1830.

    Expanded heating data is on page 18 for GSZ130241A. lists no matchup to the air handler AVPTC1830.

    You could take the numbers from those pages and use them. The worst that they can do is reject the form, but I doubt that they do anything other than file it. (government work, you know.)

    For the fan setting use B (840 high stage) on page 5 of the air handler specs.

    Thank you very much for your reply.
    I understand that only the fan speed affect other calculations on the form (i.e. duct size). I'll try my best to complete the form.

    Best regard,
