for all the advise and information. I will follow it to the letter. After I priced the humidistat's, I quickly made a decision to eliminate that option. I understand I can't get a timer in a single switch box; it has to be in it's own box, I was told. Is that the same for the double switch? I have a single switch going to the light fixture now. I was hoping I didn't have to change out boxes with the close work involved witht he drywall. Oh well, I'll do whatever's necessary. Thanks again for the excellent info. Jim
