If you do not have auxiliary relays to work with, try looking up FumeOut by LSL Products. They make a nice vent fan with a dedicated voltage controller. Only downside is it does not have a back draft damper such as the zephyr does. But it uses 2" pvc so if you wanted to get creative and make a back draft damper it wouldn't be so hard.
