DRY Mode
In general the air humidity will be reduced in cool mode. In dry mode extra dry-
ing is possible by reducing the fan speed.
Dry Mode conditions and process
The system starts cooling and dehumidifying if the ambient temperature is
higher or equal to the preset tempe2°C (T
amb
≥ T
preset
+2°C).
Under this condition the compressor and the outdoor unit fan are running ade-
quately to the requested performance. Meanwhile the fan of the indoor unit is
decelerated to LOW position.
In case of higher or equal ambient temperature in comparison to the preset
value -2°C, but lower or equal to the preset value of +2°C (T
preset
-2°C ≤
Tamb
≤
T
preset
+2°C), the system starts the dehumidifying functio n. So the fan of the in-
door unit is decelerated to LOW position. The compressor, as well as the out-
door unit fan will run for six further minutes then they are switched off for four
minutes. This cycle repeats in the DRY MODE.
In the range of ambient temperature being lower or equal to the preset value for
-2°C (T
amb
≤ T
preset
-2°C), the system will switch off the compressor a nd the fan
of the outdoor unit. The fan of the indoor unit is decelerated to LOW position.
As to that please compare the following schedule:
The temperature ranges between 16 to 30°C. On the d isplay of the indoor unit
the symbols “OPERATION, COOLING” and the temperature preset value are
indicated.
