- High-precision sensor ensures accurate temperature and pressure readings.
- Intelligent algorithm smooths power modulation for stable combustion.
- Real-time data display shows gas consumption and working status.
- Universal spare parts are easy to purchase from local suppliers.
- Long design service life reduces frequent replacement investment costs.
- Wide voltage adaptation design handles unstable power supply in many regions, working steadily under fluctuating input voltage and resisting voltage surges and drops. Sudden voltage fluctuation will not lead to unexpected shutdown or circuit board burnout — especially valuable for remote areas and rural places with poor power grid quality.
The variable-speed fan adjusts rotation speed dynamically according to combustion load and flue resistance. When heat demand rises, fan speed increases to supply enough combustion air; when heat load reduces, the fan slows down correspondingly. This closed-loop air supply control ensures an optimal air-fuel ratio in all working conditions, promoting complete combustion and cutting NOx and CO emissions.
The fan adopts a high-temperature-resistant motor with lubricated bearings, featuring low vibration and low noise during continuous operation. It also provides flue pressure detection. If the exhaust flue is blocked by debris, bird nests, or ice, the fan pressure sensor detects abnormal back pressure, and the boiler stops gas supply and triggers a fault alarm immediately to prevent flue gas leakage into living space.
The fan motor is easy to disassemble for inspection and replacement, lowering maintenance difficulty for after-sales technicians in long-term service.
A1: Common causes include an oversized boiler, air in the system, or incorrect thermostat location.
A2: If there is no water flow, the boiler shuts off the pump to avoid burning out the pump motor.
A3: A professional descaling chemical recommended by a trained technician is advised.
A4: Heavy scale causes local overheating and can burn through the heat exchanger.
A5: Shut off the gas and power, isolate the water supply, and contact a heating engineer.
A6: Do NOT switch any electric switch. Open windows, close the gas valve, and call the gas supplier.
