Two grade antifreeze device: when the water temperature of the system is less than 8℃, it enters the first level antifreeze, that is, the pump runs automatically. The pump stops running and exits the freeze proof state until the temperature is more than 12℃. When the system water temperature is less than 5 C, it enters the two level antifreeze. That is, the boiler starts ignition heating and stops at 30℃. However, in some cases, if there is a large natural temperature difference between the wall and the furnace, the frost protection function will be affected.
• Anti stagnation function: each standby for 24 hours, the pump automatically circulate for 1 minutes, three way valve automatically advance and retreat once.
• Limit temperature protection: when the water temperature rises to the limit temperature, the gas source is automatically cut off and the gas boiler stops.
• Excessive wind pressure protection: when the wind pressure is too high, the fan fault or smoke exhaust is blocked, the gas source is automatically cut off and the boiler stops working.
• Flame out protection: When the system flame out during use accidentally, it can automatically cut off the gas source. The gas will not leak out and it will display the fault code.
• Quick information touch button
To provide boiler status and diagnostic information.
• Quick-set heating and hot water temperatures
