Description

<Cooling operation>

1)The control target temperature increase 1.0°F (0.5ºC) per hour up to 3.5°F (2°C) starting from the set temperature when ECONO has been received.

2)The indoor fan speed is depend on presetting and can change every speed after setting ECO operation.

3)The compressor speed is controlled as shown in the left figure.

<Heating operation>

1)The difference of room temperature and set temperature are separated in to A zone, B zone and C zone.

Three zone will changed again 30 minutes after ECO operation start.

2)The compressor speed is controlled as shown on the table.

3)The indoor fan speed is not controlled and can be selected during the ECO operation.
