3.14.3 4D hot air / CircoTherm
• PID control (Page 35)
- Accuracy: ± 10 K
- Peak heat: up to 20 K (if starting at room temperature)
- Heating element: Ring heating element
• Special features and characteristics:
- Circulated air motor changes rotation direction
- If the target temperature is > 275 °C, then after 40 minutes the
temperature will be reduced to 275 °C
- Can be combined with microwave and also with steam
