Control contents
When using the power saving function, turn on switches.
The maximum operating current of the COOL/HEAT operation can
be limited by dropping the current release point of the outdoor unit.
When using the outdoor unit as a cooling-only machine, turn on
switches. ("OF" of DN cord on the remote controller also can be
used for changing the machine to the cooling-only model.)
Control contents
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
(Max: Upper fan: 890 rpm / Lower fan: 910 rpm (WF)).
In this case, the upper limit value of static pressure for duct is 5Pa
or less on 77°F (25°C) degrees and please use straight duct.
In this case, the outdoor noise level may increase.
Turn the switch to ON when using the power save function.
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 32°F (0°C) though the compressor
stops, the outdoor fan operates with W5.
The defrost interval is cut to shorten it than the standard status.
For contents of control and cutting method, refer to
10. Defrost control (See to Page 43).
When it is needed to lower the maximum value of the compressor
frequency, cut the jumper line. Max. frequency at cooling/heating is
lowered.
In this case the Max. capacity decreases.
