CONTROL METHOD FOR GAS FAN HEATER

CONTROL METHOD FOR GAS FAN HEATER

The gas fan heater controlling method detects the voltage difference caused by an oxygen deficiency or a gas shortage by use of a flame rod, so as to determine the time of ventilating the room or supplying the gas. The control method comprises a step (100) of deciding a flaming level; a step (101) o...

Zusammenfassung:The gas fan heater controlling method detects the voltage difference caused by an oxygen deficiency or a gas shortage by use of a flame rod, so as to determine the time of ventilating the room or supplying the gas. The control method comprises a step (100) of deciding a flaming level; a step (101) of deciding a short level if the detected voltage is more than the flaming level in the step (100); a step (104) of deciding the oxygen deficiency level if the detected voltage is less than the short level; a step (112) of ventilating the room if less than the oxygen deficiency level in the step (104); a step (108) of deciding if the flame gets extinguished or not; a step (109) of detecting the gas shortage level.
