方快燃气热水锅炉防护装置

Multiple protection functions ensure safe and stable operation of the boiler

Voltage ultra-high and ultra-low protection: When the power supply voltage exceeds the normal range, the boiler power supply will be automatically cut off and an alarm will be triggered.
Abnormal protection of temperature sensor: After each start-up, the boiler control system first detects the condition of the sensor. If there is an abnormality, the boiler power supply will be automatically cut off and an alarm will be triggered.
Water shortage alarm function: When the boiler water level is lower than the safe water level, the boiler power supply will be automatically cut off and an alarm will be triggered.
Triple temperature protection system, triple pressure protection system
Antifreeze protection system
Burner shutdown fault alarm, motor overload, fault protection
