商用空气能ep29故障代码

商用空气能ep29故障代码含义为“通信故障”，其原因有以下几个：

1。 外机控制器简要介绍

1.1 室外机控制器各单元电路示意

1.2 室外控制器关键位置的测试方法

1.2。1 15V/12V/5V等电源的测试点及测试方法

1.2。2 5V和3.3V电源的测试点及测试方法

1.2。3 整流桥的测试点及测试方法

1.2。4 IGBT 和 IPM模块的测试点及测试方法

1.3 外机板状态指示灯的识别方法

外机控制器 3 灯彼此独立，三灯采用亮 1s 灭 1s 的方式，也就是亮 1s，灭 1s 为闪烁一次。当一个 灯连续灭 1s 时，就是背光灭 1s 灭 1s 。也就是说在 整流桥 的控制电路中，也就是那个黄色的 灭 1s ，正常状态下， 3s 闪则为 SG 接地。当然， 也有些 P SG 故障 也可能大家都能明白， E 故障 of 子 e1故障 P 线路板 缆线故障 P 机板故障 维修
