Date & Time 2012/01/21 - 00:36 AM
Outdoor temp: 3 degree C
Inner temp: 20 degree C
I heard the noise and recorded it when heating is on about 2 minutes later, but there is no noise at 5:40 - 9:50 from the scroll bar when heating is off that it may be at 7:40, and the noise appear again after 9:50.
Can anybody tell me what cause this kind of noise?
Thank you.
