The thermostat controls operating temperature. This occurs at a preset temperature (typically 195 degrees F. or so), which is usually stamped on the thermostat itself. The thermostat should be fully open about 20 degrees F. above the rated temperature. So your operating temperature is about right. If you have doubts, just replace the thermostat with a new one of the correct temp.
