Turn the switch to ON when mounting a duct to the discharge port
of the outdoor unit. Add 3 taps to the upper limit value of the
outdoor fan tap.
The operation is performed with
The operation is performed with
(Max: Upper fan: 890 rpm / Lower fan: 910 rpm (WF)).
In this case, the upper limit value of static pressure for duct is 5Pa
In this case, the upper limit value of static pressure for duct is 5Pa
or less on 25°C degrees and please use straight duct.
In this case, the outdoor noise level may increase.
In this case, the outdoor noise level may increase.
Turn the switch to ON when Ø19.1 is used for the existing pipe.
In this case, the heating capacity may lower according to outside
In this case, the heating capacity may lower according to outside
temp. and indoor temp. in heating operation.
Turn the switch to ON when using the power save function.
The control to lower the compressor frequency (Approx. –10%) is
The control to lower the compressor frequency (Approx. –10%) is
performed by indoor heat exchanger temp. in heating operation.
When snow enters from clearance of the fan guard or heat
exchanger into blast path and it is accumulated, the control to
prevent generation of motor lock is validated.
When outside temp. is below 4°C though the compressor stops,
When outside temp. is below 4°C though the compressor stops,
the outdoor fan operates with W5.
The defrost interval is cut to shorten it than the standard status.

7-10. Defrost control.
When it is needed to lower the maximum value of the compressor
frequency, cut the jumper line. Max. frequency at heating is
lowered.
In this case the Max. capacity decreases.
In this case the Max. capacity decreases.

When using the air conditioner as a cooling-only conditioner, cut
the jumper line. (An air conditioner can be changed to cooling-only
conditioner by “0F” of DN code on the remote controller.)
