Temperature-Based Control
Temperature-based control operates the system and controls the heating process based on temperature feedback from thermocouple inputs. Ther-
mocouples must be used for this mode of operation or the system will not operate. Within the temperature-based mode there are four different
processes available as follows: Preheat, Bakeout, PWHT (Post-Weld Heat Treat), and Custom Program.
Press the Program button to access the programming mode. Use the cursor button to move the cursor to the desired temperature-based process,
then press the Program button again to select the process.
