2.3 Temperature Control
The internal temperature of this projector is monitored by the sensors (the Lamp thermistor, L/
V thermistor) in order to protect the projector from internal overheat, which may cause unsafe
state or damage to the projector. The fans’ revolutions are controled according to the detected
temperature data. The fans’ revolutions are altered by changing the driving voltage based on
the detected data. In this way, the ventilation level is optimaized and the internal temperature is
kept stablized.
