Other

Timer Type
There are two different Timer Types:

• no PWM
• VW

The Timer Type is the algorithm for a delayed charge (for example, a scheduled charge). The type of algorithm used depends on the vehicle. If a scheduled charge does not work as expected, try using a different Timer Type for better results. Contact technical support before setting it if you need clarification on whether you require Adaptive Mode.

Minimum Voltage, V

• Minimal voltage is the lowest voltage at which a charging session will proceed. The charging session will not start or will be interrupted if the measured voltage is below the set minimum.
