How to switch between different modes of temperature display?
- On the back of the main unit, press DISPLAY button.
- Rotate the knob to select a temperature display mode:
- Display indoor temperature.
- Display outdoor temperature.
- Display indoor and outdoor temperature alternatively.
- Press the knob to confirm.
If the main unit fails to receive signal from the sensor (or if the sensor does not send signal to the main unit), only the indoor temperature can be displayed.
