If there's moisture in the air, a too-cold evaporator would freeze moisture condensed from the air, blocking the air flow unless compressor was allowed to cycle so such ice would melt.
Question for professionals: if such system was allowed to have compressor run but little evaporation of refrigerant occurred in the evaporator (due to low air flow), wouldn't that mean that possibly liquid refrigerant would get back to compressor, and subsequently damage that ???
Well, they cycle somewhat above 32F or it seems so from vent temperature so I guess they were trying to squeeze the coldest output possible.
