Question
Is it the intent of the code to classify a sunroom as category IV or V if a mini split unit is installed but only to dehumidify the room?
Answer Published 01/27/2014 at 7:30 PM
Yes
Commentary
A mini split system that could provide cooling added to the
sunroom would place the room in category IV or V, depending
on thermal isolation or lack thereof from the primary
structure. All applicable code requirements would apply.
To be exempt, the unit must be controlled by a humidistat
only.
