To reset the switch you ll need to climb up into. So even though there s no single ideal temperature you do want a 16 22 f difference from the supply air and return air. It also means that the air in those ducts is continually exposed to the ambient temperature in the attic. Well there s not a universal fixed temperature your ac should always be blowing.

So why put an hvac system up in the attic at all. There too unless the supply duct is long uninsulated running in a hot space such as an attic the air temperature at the supply register should be around 55 degrees.
