Inquiry (采购产品): Thermostst installation I am installing one of your 120 volt thermostats for my swamp cooler. Does it make any difference which lead goes to each of the connections? If it does, how do I tell which is the hot line? Thank you **** Hidden Message ***** Lee Berry 84037 Company: Residence E-mail: clberry743@hotmail.com **** Hidden Message ***** clberry743@hotmail.com
