Pairing is a one-time process. We recommend pairing while the fan is newly installed. To pair RF remote with the fan, first, you need to turn on the power source, then press the power on/off button on the remote for 3-6 seconds or until you hear the beep voice 2-3 times. Leave the power button when the beep sound is heard twice or thrice. The fan should be paired with the remote
You should only turn the power source on for the fan you want to pair if there is more than one RF-controlled fan in the closed proximity pairing process could be troublesome. Also, remember that you should never connect the DC fan with the dimer/regulator as it can cause damage to the PCBA.
