*Some Brushless PWM controlled fans/pumps may require a switched power source. Without a switched power source, the fan/pump may run at full speed or drain the battery when a pwm signal is not present (e.g. VSFM-002 is powered o�). Other fans/pump do not require a switched power source, and will go into a low power mode when a pwm signal is not
present. Check your fan/pump documentation to determine if your fan/pump requires a switched power source.

APPENDIX AAdvanced Settings:The advanced settings affect the Temperature Controlled PWM mode and the User Controlled Fan/Pump Speed %Mode.
When DIP switch #4 and #5 ARE NOT positioned in the same direction, the Override Input logic is reversed.
• Insteadofthefan/pumpoperatingatmaxspeed(TemperatureControlledPWMMode)orInputActivationSpeed%(UserControlledFan/PumpSpeed%Mode)whenthereisanOverrideInputActivation signal present, the fan/pump will operate at full speed or Input Activation % when an OverrideInputActivationsignalisnotpresent.
