Hi I bought a ifan03 I installed and unable to sync to my wifi as 5ghz was still available. After sorting my router I could not get the unit to go into beep mode. My remote worked and using the remote buttons for WiFi or the button on main unit will not beep and then to top it off I installed it to the Dan to use in remote mode the unit will not respond. I can now only turn light on/off by pressing main switch on unit even if unplugged for hours no beep nothing. So a ceiling fan I could use in height of summer is now not usable.
