My 50 year old house does not have a bath fan and i am planning on adding one
I have noticed that the humidity can get fairly high after a bath and wondered if using a dehumidistat would be a better control for the fan ?
And could i control the fan with a dehumidistat and a timer in parallel for the times when the humidity is lower but the odors are high?

yes you can get fans with both humidity control and a timer.
the humidistat over rides the timer control so that if the numidity is still above the set level it will keep on running.
I don't know of those with internal humidistats have the connection for also controlling them with a timer or not.
But you can get separate humidistats and wire them in parallel with a timer.
Also the number of models with builtin humdistats are fairly limited.
Connecting both a crank timer and a dehumidistat control to a bathroom exhaust fan (hard ducted directly to the outside of course)is an excellent system. It will not only automatically evacuate the humidity from it's source, it will also help keep the relative humidity of the majority of the house low which is key to preventing moisture problems during the heating season.
Here is a website to a supplier that I often use. Their staff is very knowlegable about the electronics of the exhaust fans, all of the different controls, and which ones will work together.

Don't bother with the humidistat ($$$$) or the crank timer....HD sells a nice Leviton digital timer with 5,10,15,&30 min and on/off buttons......hit it when you get in the shower, turns itself off, & doesn't have that tick tick sound.....just my 2C worth
Thanks all for the replies.
