  Alerts for high temperature, voltage irregularities, and system faults.

How It Works

The controller automatically regulates pump speed and fan operation based on coolant temperature, ensuring efficient thermal management.

• Pump operation adjusts dynamically for optimal cooling
• Fans activate progressively based on user-defined temperature thresholds
• After shutdown, the system continues to cool for up to 3 minutes if required
