Control light and a time delayed bathroom fan with one double pole switch?

[hbiss]

I would love to have a discussion with the enginers at Panasonic as to what they were thinking when coming up with this design. All they had to do is use a black as constant power and red as a switch leg. Simple 14/3 to switch.

Apparently, they had little knowledge of the NEC and the probability that installers would have other ideas beyond the limited examples they show in their instruction sheet. Looks like it caters to the DIY, else there would be details such as what the control wiring is that professionals would understand and use. Panasonic is famous for that.
