1. Manual control: Manually adjust the duty cycle of the PWM port to control the power of the dew heater(0-255).
2. Constant temperature control: WandererBox will keep the dew heater temperature constant at the set value.
3. Dew point temperature difference mode: WandererBox will regulate the temperature of the dew heater to maintain a fixed value higher than the dew point. It saves power and prevents condensation effectively. It also ensures that the dew heater does not overheat, ensuring good image quality.
