#1048 Ducts Too Large For Attic (but no attic) / Division by Zero

[Dee Anne Ross]

Two related issues. The file (unused attic duct error.ribd16) has a field "Attic (activate by creating a 'Ceiling (blow attic))," the ducts are in another location, yet the file results in this error until this row is deleted [SIDE NOTE/2nd file: In the past I have noticed the unactivated attic on the CF1R. This is the first time I can remember it causing an error (attic demo.ribd16 and pdf demonstrate this other related issue)]:

Division by zero evaluating rule: Rule 146, 14, 'Rules_Default_HVAC.rule' Line 3328: Set HVACDist:DuctsTooLrgForAttic - Flag indicating ducts too large for attic (0=they fit, 1=Supply too large, 2=Return too large, 3=No default Attic)

Error encountered evaluating rulelist 'ProposedInput'

Believe this is related. When there is no other option for hypothetical ducts (whether no cooling or minisplit), put them in conditioned space.

Attic demo.ribd19 - file ran without issue, so I'm not sure if the division by zero item is still a problem
