Low 12 volt voltage will not cause the relay to stick. Low voltage (12 volt)would cause the relay to NOT close. Low or High 120 will not really affect the relay unless the low 120 voltage(under 104 volts consistantly), would cause the points in the relay to arc and pit and that causes the relays to "weld" closed. Your problem is NOT the wall tstat. I cannot remember the last time I replaced a 5 button wall tstat. Doug
