Inquiry (采购产品): FL Blinking Thermostat I have a Columbus Electric wall mounted thermostat. It reads room temperature BUT recently the reading shifts back and forth from temp to "FL". What's the significance of this?. I changed the batteries, but the action didn't stop. Thanks Bob Shair crjazl@aol.com or 954-961-5074.. Thanks and Best Regards, Bob e-mail is best **** Hidden Message ***** Bob Shair 4921 Sarazen Drive Hollywood, FL 33021 USA Company: BCCollege Title: Professor Phone: 954-961-5074 E-mail: crjazl@aol.com **** Hidden Message ***** crjazl@aol.com
