6.4 Brief Description of Modes and Functions

1.Temperature Parameters

Indoor preset temperature (Tpreset)
Indoor ambient temperature (Tamb.)

2.Basic functions

(The temperature in this manual is expressed by Centigrade. If Fahrenheit is used, the switchover between them

Tf=TcX1.8+32.)
Once the compressor is energized, there should be a minimum interval of 3 minutes between two start-ups. But if the unit is de-
energized and then energized, the compressor can restart within 3 minutes.

(1)Cooling mode

①

Cooling conditions and process

When Tamb. ≥Tpreset, the unit starts cooling operation. In this case, the compressor and the outdoor fan operate and the indoor fan
operates at set speed.
When Tamb. ≤Tpreset-3°C, the compressor and the outdoor fan stop while the indoor fan runs at set speed.
When Tpreset-3°C<Tamb.<Tpreset, the unit will maintain its previous running status.
In cooling mode, temperature setting range is 16~30°C; the indoor unit displays operation icon, cooling icon and set temperature.

②

When outdoor unit has malfunction or stops for protection, indoor unit will keep previous operation status and display malfunction

code.

③

The protection status is as the same as the cooling mode.

(2)Dry Mode

When Tamb.>Tpreset, the unit operates in cooling mode. Meanwhile, compressor and outdoor fan operate, and indoor fan operates at
set fan speed (low fan speed, quiet fan speed or auto quiet fan speed).
When Tpreset-2°C<Tamb. ≤Tpreset, the unit keeps previous operation status.
When Tamb.≤Tpreset-2°C, compressor, outdoor fan and indoor fan operate at set fan speed (low fan speed, quiet fan speed or auto
quiet fan speed).
Under this mode, the temperature setting range is 16~30°C. Display displays operation icon, drying icon and set temperature.

(3)Heating mode (not available for cooling only type)

①

Heating conditions and process

When Tamb. ≤2°C, the unit starts heating operation. In this case, compressor and outdoor fan operate simultaneously; the
indoor fan operates at cold-air prevention mode.
When Tamb.≥5°C, the compressor and outdoor fan stop operation; the indoor fan blows residual heat.
When 2°C<Tamb.<T5°C, the unit will maintain its previous running status.
Under this mode, temperature setting range is 16~30°C; the indoor unit displays operation icon, heating icon and set temperature.

②
