To change input types, alarm settings, or PID values, you must enter the Parameter Setting Mode.

If you are in a production emergency and need the most common parameters from the , here is a generic cheat sheet. Use at your own risk – these are typical defaults.

To change the set temperature (SV):

Crucially, this section elucidates the specific terminal designations. Unlike consumer electronics, industrial controllers have varying wiring requirements depending on the specific model (e.g., voltage input range, output type). The manual provides the necessary nuance, guiding the user on how to correctly wire the sensor inputs (positive and negative polarity for thermocouples) and the output control lines. By strictly adhering to these guidelines, users mitigate risks such as short circuits, equipment damage, or inaccurate sensing, thereby ensuring the system’s foundational safety.

This defines the "gap" where the unit turns back on. For example, a 37°C setpoint with a 3°C differential means the unit turns off at 37°C and restarts at 40°C (for cooling).
