As the title states my Quad Mount Vernon,reads 25 degrees F,room is at 70 degrees,& hold at -17 degrees, How do I reset this? You can do a temp recalibration,that only changed it to around 35. My Grandson was seen playing with thermostat(he is a 19 months) don't know for sure if he caused something or it if it went goofy on its own. So does anyone have a recalibration procedure,where to get one,or where to get diagnostics for this thermostat/module unit? Thanks anyone an everyone for your help in advance,WI Dale
