SCSInet, would you say the heater is "reset-able" or should I just lower the setting ??
It depends on the heaters. Some heaters can be re-calibrated, but MOST cannot. For the answer on that, you'll need to check the documentation. I know that Jagers are, but I do not know of others for sure. I do not believe that a heater having inaccurate calibration translates to a definite upcoming catastrophic failure. The thermostats in heaters are just not very accurate, end of story. So all you really need to do is compensate when you set it.
In fact, many things that handle temperature that are made for aquarium use are not very accurate. Case in point, I found out earlier this week that my Lifegard digital time/temp thingy was lying to me to the tune of 4 degrees, when I checked it against a lab thermometer.
Ranco controllers however are industrial grade devices that are made to be dead-on accurate. These things are used for industrial processes that require very tight temperature control, so they as a whole tend to be more accurate - but very expensive.
