| Parameter | Function | Default | Range | Explanation | | :--- | :--- | :--- | :--- | :--- | | | Temperature correction (calibration) | 0.0 | -9.9 to +9.9 | Adds or subtracts degrees to match a reference thermometer. | | P1 | Hysteresis (Backlash) | 2.0 | 0.1 – 30.0 | The deadband between ON and OFF. Example: Set to 25°C, HYS=2 → heats to 25, stops, restarts at 23. | | P2 | Maximum temperature limit | 120 | -50 to 120 | Prevents setting a target above this value. | | P3 | Minimum temperature limit | -50 | -50 to 120 | Prevents setting a target below this value. | | P4 | Delay start (compressor protection) | 0 | 0 – 10 minutes | Prevents rapid cycling. Output only activates after this delay from power-on. | | P5 | Temperature unit | 0 | 0 = °C / 1 = °F | Switches display from Celsius to Fahrenheit. | | P6 | Mode lock | 0 | 0 = unlocked / 1 = locked | Prevents accidental parameter changes. | xh-w1219 manual pdf
