We recently moved into a new house that has a Ritetemp model 6080 thermostat. I don't have a manual and the file from the Ritetemp website says it is damaged so I cannot view it. I cannot figure out how to reset the air to a permanent temperature. I try to set it at 76 and it keeps blinking "temporary cool" and then reverts back to 70 degrees which is too cool. I am pretty competent when it comes to this kind of thing but for the life of me I can't figure this one out!
