Inquiry (采购产品): Setback pins I have a thermostat Model 1F72-20 and have lost the blue pin that turns the AC/heat off. The red pins are still there, but the thermostat does not operate in the on/off mode without the blue pin. I realize that this is an old model, but it is working and I do not want to replace it at this time. Can you supply the blue pins for this model? Thank you for a prompt reply. **** Hidden Message ***** Susan Marinbach 11552 USA Company: Nu-Life Restorations E-mail: gutchin@yahoo.com **** Hidden Message ***** gutchin@yahoo.com
