4.Applications
- Smart Home/IoT Scenarios: Users can remotely turn water on/off, adjust water temperature, and schedule heating via a mobile app, and receive water consumption analysis and energy-saving suggestions.
- Safety Protection Scenarios: Installed on the power cord, it monitors the current difference between the live and neutral wires in real time. Upon detecting leakage within 30 mA, it can instantly cut off the power within 0.1 seconds, ensuring personal safety.
- Extreme Environment Application Scenarios: Utilizing low-temperature and high-pressure resistant components, it possesses enhanced heat dissipation and heating capabilities, ensuring stable startup and operation even in environments with temperatures as low as -30°C or unstable voltage.
- Multi-functional Integration Scenarios: A three-in-one heat pump system. It simultaneously controls underfloor heating, domestic hot water, and cooling. In summer, it recovers waste heat to produce free domestic hot water during cooling, and in winter, it provides both underfloor heating and domestic hot water, maximizing energy utilization.
