3. Briefly press the operating button to select the correct function:
■
Controller function: The CO
2
LED turns green ; the bottom two LEDs on the right turn
red.
■
Sensor function: The CO
2
LED turns red ; the bottom two LEDs on the right turn red.
4. Press the operator button for 5 seconds to confirm the selection:
■
All LEDs on the right blink green 3 times.
