-6. Overload Prevention (Heating)
●
Overload prevention
a
v
oid
s overheating of the indoor heat exchange coil. This function works either when
the temperature of indoor heat exchange coil
ris
es up or compressor current rises to a certain level.
■
Temperature of indoor heat exchange coil sensor
●
When the temperature of the indoor heat exchange coil rises above A2°C, and if the indoor fan is L (low speed),
the fan speed changes from L (low speed) to M (medium speed).
●
When the temperature of the indoor heat exchange coil rises above A1°C, the outdoor fan stops.
The operation temperature
s
shown as A1, A2, A3 and A4 in the chart differ
s
by models.

■
Compressor current detection
●
When the compressor current rises above B1(A), and if the indoor fan is L (low speed), the fan speed
changes from L (low speed) to M (medium speed). At the same time the outdoor fan stops its operation.
●
When the compressor current drops to B2(A), the outdoor fan resumes its operation.
●
When the compressor current drops below B3(A), indoor fan returns to operate in set speed.
The compressor current shown as B1, B2 and B3 in the chart differ
s
by models.
