海尔变频空调因型号不同,e1的含义也不一样,因氟压力过低则显示e1,多数是内机环境温度传感器,也有可能是模块,
以下代码适用于海尔kfr-48lw/bpjxf、kfr-48lw/bpf、kfr-50lw/bpjxf、kfr-51lw/bpjxf、kfr-51lw/bpjf、kfr-51lw/nbpf、kfr-51lw/tbpjxf、kfr-51lw/bpjxf、kfr-52lw/bpjxf、kfr-52lw/bpjf、kfr-52lw/ebpjxf、kfr-52lw/nbpjxf、kfr-58lw/tbpjxf、kfr-58lw/bpf、kfr-58lw/bpjxf、kfr-60lw/bpjxf、kfr-58lw/bpjxf、kfr-58lw/ebpjxf、kfr-58lw/nbpjxf、kfr-58lw/nbpf、kfr-60lw/bpjf、kfr-60lw/bpxf、kfr-60lw/ebpjxf、kfr-68lw/bpjxf、kfr-68lw/ebpjxf、kfr-68lw/bpjxf等空调。
