Inquiry (采购产品): 110 volt fan control I have a small greenhouse and I need to control the exhaust fan. Fan on at 90 degrees F and fan off at 80 degrees F. Do you have something suitable for this? **** Hidden Message ***** Stephen Gustkey 16001 USA Company: none E-mail: chiefgust@zoominternet.net **** Hidden Message ***** chiefgust@zoominternet.net
