Outline of specifications
1) Selecting [AUTO] mode enables an energy-saving to
be operated.
2) The setup temperature is shifted (corrected) in the
range not to lose the comfort ability according to input
values of various sensors.
3) Data (Input value room temp. Ta, Outside temp. To,
Air volume, Indoor heat exchanger sensor temp. Tc)
for 20 minutes are taken the average to calculate
correction value of the setup temperature.
4) The setup temperature is shifted every 20 minutes,
and the shifted range is as follows.
In cooling time : +1.5 to –1.0k
In heating time : –1.5 to +1.0k
1) This control is operated by selecting [AUTO] operation
mode.
2) COOL operation mode: the frequency is controlled
according to the following figure if To < 28°C.
3) HEAT operation mode: the frequency is controlled
according to the right figure if To > 15°C.
1) When the fan operation has started, positioning of the
stator and the rotor are performed.
(Moves slightly with tap sound)
2) The motor operates according to the command from
the indoor controller.
NOTES :
• When the fan rotates while the air conditioner stops
due to entering of outside air, etc, the air conditioner
may operated while the fan motor stops.
• When a fan locking is found, the air conditioner stops,
and an error is displayed.
