Abstract
PURPOSE:To protect outdoor electric parts even if the temp. in an outdoor electric box rises up abnormally by a method wherein an indoor power relay controlling voltage supplied to the parts is so controlled as to be cut off when an abnormal temp. rise at the outdoor side is detected. CONSTITUTION:A temp. fuse 13 is placed at an outdoor interface part. When the temp. in an outdoor electric box rises up abnormally and the fuse 13 is cut off, an I/F signal transmitted from the outdoor side to the indoor side continues to keep LOW condition. An indoor control circuit 3 judges that the I/F signal transmitted from the outdoor side to the indoor side keeps LOW condition for a second and, at that time, a power relay 4 is OFF and an operating display is turned on and off at a pitch of constant time. At the stop time of an outdoor apparatus caused by overcurrent, etc., the LOW condition of the I/F signal transmitted from the outdoor side keeps only for 230mSec and this case therefore does not belong to this mode and the power relay is cut off after 3 minutes and can be ON again on a later main operating ON signal.
