Would this be the correct way to add a timer switch to an existing fan with thermostat?

Question

We have an existing 120V AC exhaust fan wired to simple inline attic fan style thermostat. We would like to add a timer switch so the fan could be manually turned on as needed.

Would this be the correct way to add a timer switch?

This is the sort of timer switch we are looking to add: 12 hour timer

Answer 1

Yes, that is precisely correct. Though I prefer red tape, but that's a preference, not a requirement to go buy a roll. Nicer (IMHO) because you can easily mark switched hots whether they be black or white.
