Hi All, Part of a remodel project at a customer's house is an audio room. Basically a large closet size room where all the electronics are going to reside on a designated rack. A temp of no more then 75F needs to be maintained in the room. We installed a Panasonic 50cfm Whisper Ceiling exhaust fan. I need a a thermo-switch to control the fan. It needs to fit either in a single/double gang box or inside the fan housing. Any ideas of a model and where to source would be welcomed.
