The outdoor sensor does not match the host?
Please put the outdoor unit and the host together first. Then, power on the host first. After the host is powered on, the signal icon will flash. At this point, open the battery cover of the outdoor unit and dial to the channel you want. Power on the host again. The corresponding channel will display the reading successfully.
If you want to clear the matching history and re-match after you have powered on the main unit, you can long press and hold the CH to make the product enter the matching state again (link signal indicator flashes), and then power on the outdoor unit again,then they will connect again.
We have a detailed operation video introduction on the corresponding website, you can visit the webpage for more detailed introduction. Thank you
