Remote controller does not work.


 Cause 2


             1. Infrared wireless communication uses data exchange between the remote controller and the air conditioning unit

             2. Intermittent malfunctions of the remote control can be the result of another source of light interfering with the infra red remote signal

                For example tri-color Fluorescent lamps emit a lighting spectrum which overlaps that of the remote controller signal and affect the remote control capacity.


 How to fix indoors


             1. Try using the remote controller with the indoor lamps off.

                  If a remote controller works fine, a fluorescent stabilizer needs to be replaced with a mechanical one.
