Notes:
• The operating temperature for the fan is higher than the ambient temperature, because the microcomputer
reads the temperature at a sensor inside the unit.
• If a critical signal for the address circuitry is input, the fan may be activated at a temperature lower than the
set temperature indicated in the above figure.
• If the voltage of the DAC output for the external fan falls, the rotation speed of the fan will become higher.
