4.

5. Using a no voltage a-contact input of the external input (sold separately), the following operations are available:
Between 1 and 2: Selecting the remote controller operation (Invalid/Valid)
Between 1 and 3: Adjusting the ventilation fan speed (Low/High)
Between 1 and 4: Selecting the ventilation mode (Bypass mode/Heat exchange mode)
Between 1 and 5: Operation (ON/OFF)
Use a microcurrent contact (DC12V, 1mA). In addition, ON/OFF operation is possible when using a voltage of
DC12V or 24V.
6. Blue wire (High) is connected as factory default. To switch to "Extra High", connect black wire's connector
instead of blue.
7. When the temperature of the outdoor air is below -10°C, the unit runs in the cold mode (the ventilator for air
supply runs intermittently). The unit cannot run when the temperature of the outdoor air is below -15°C. The
ventilator for air supply stops running and the ventilator for air exhaust also stops depending on the settings.
8. Even if "Bypass mode" is selected manually, the unit switches to "Heat exchange mode" automatically to prevent
condensation when the temperature of the outdoor air is below 15°C. However, "Bypass mode" is still displayed.
