■ 安全：平衡式燃烧设计，使燃烧所需的空气取自室外，而燃烧时所产生的烟气强制排出室外，确保室内空气清新，使用安全可靠；燃烧室完全独立设计，使壁挂炉的使用寿命得以延长。
Safe:With close gas supply and exhaust design, this product gets fresh air for combustion from outdoor, and the waste gas is exhausted outdoor through double-layer with same axis gas supply and exhaust pipe.Such design can ensure safety. Combustion camber is totally isolated from other components, in this way it can effectively prolong the service life of electric component.

■ 环保：负压强化燃烧技术改变空气流向，让更充分的空气参与燃烧，使燃烧更加安全，烟气中的CO含量小于0.01％，利于环保。
Environment friendly: Negative enhanced combustion technology changes the air flow direction, in this way more air can be combusted and the combustion is complete. The CO content in the waste gas is lower than 0.01％,so it is environment friendly.

■ 闭式系统：闭式水路设计，内置膨胀水箱，供暖循环水与大气完全隔离，不易结水垢，对供暖系统的腐蚀小。
Close system:With close waterway design and built-in expansion water tank,the circulating hot water is totally isolated from atmospheric air, so it is hard to form scum and it can reduce the corruption of heat supply system.

■ 防冻结装置：当循环水温度降至6℃以下时，水泵运转，燃烧器以**小功率燃烧，水温升至20℃时停止。
Frostbite-proof Device: When the temperature of circulating water is lower than 6℃,the water pump automatically running.At that time,the combustor runs at the lowest power. When the temperature reaches 20℃,the combuster stops running.

■ 水泵防卡滞功能：每待机24小事，水泵自动运作1分钟。
Lock-proof function of water pump:Every time the machine stands by for 24 hours, the water pump will automatically run for 1 minute.

■ 水泵旁路保护装置：当供暖主回路意外关闭，水路循环停止时，旁通阀自动打开，以保护系统及水泵。
Bypass protection device of water pump: When the main heat supply loop is closed by accident and the waterway circulation stops, the bypass value automatically open to protect the system and water pump.

■ 主回路流量监控装置：当主回路流量太小或水循环意外停止时，自动关闭系统。
Flow monitoring device of main loop: When the flow of main loop is too low or the circulating water stops by accident, the system will be automatically closed.

■ 极限温度保护装置：水温升高到极限温度时，关闭燃气比例阀，系统停止工作。
Limiting temperature protetion device:When the water temperature reaches limit,the combustion proportional value will be losed and the system stops running.

■ 风压过大保护装置：当风机故障、烟道堵赛、风压过大时，燃烧自动停止。
Air pressure protection device: When the fan doesn"t work, or the flue pipe is blocked,or the air pressure is too high,combustion will automatically stop.

■ 供暖系统水过压安全保护装置：系统水压升至3bar时，安全阀自动打开泄压。
Heat supply system water pressure protection device:When the prssure of system water is above 3 bar,safety value will automatically open for reducing the pressure.

■ 熄火保护功能:燃烧器以外熄火时，燃气比例阀自动关闭。
Flame-out protection device: Wher the combustor quenches by accident,combustion proportional value will be closed automatically.

■ 水温传感器失效保护：当供暖或生活热水水温传感器故障短路，断路或阻值异常时能自动显示故障代码。
