房部匹半美的分體神神地,
有幾次行得好地地,
當開啟其他電制時(如房燈, 套廁抽氣),
佢就"o都..o都"二聲,
停止運作,
按remote任何制都冇反應,
要熄左電源制再開過至正常番,
有冇CF可以解釋係咩問題???
係咩保護線 ...
I think it is the microcontroller hang up due to EMI interference. You mentioned that you have to power reset to make it work again so I don't think it is the IR receiving wrong signal. Try to add some EMI filter in the power |
