1. . For the indoor failu ，only running LED ON remote receiver will indicate.
2. . For the outdoor failu ，timer LED and running LED will indicate.timer LED of remote receiver stands for ten's place,and running LED
stands for one's place.timer LED will flash firstly,2 seconds later,running LED will flash too. Afer that,4 seconds later,they will flash in
turns again.Flash times equals to the failure code of outdoor plus
20.For example,failure code of outdoor is 2,the indoor unit should display 22.As a result,timer LED flashes twice firstly,then running LED
flashes twice.
