Function and Control
• URURU HUMIDIFY operation
This air conditioner enables uniformly humidifying the room by circulating moisture with
warm air.
Powerful humidifying ability
The values above are measured at 7°C DB / 6°C WB of outdoor air and with 4 m of
humidifying hose length.
No need for water supply nor cleaning
Water supply and cleaning are unnecessary as it does not have water tank, unlike
humidifiers, and there is no proliferations of bacteria.
Humidity control
The target of the humidity level is 40 to 50%RH.
You can select from
LOW
,
STD
(standard),
HI
(high),
CONT
(continuous), and
MOISTURISING
. The target humidity cannot be set by %.
Note
When the outdoor temperature and humidity are low, the humidifying capacity is decreased.
In addition, the moisture in the room may not attain sufficient humidity when the ventilation
volume is high, the preset temperature is high, or the preset humidity is high.
After the HUMID HEATING operation starts, the relative humidity in the room lowers
temporarily. This phenomenon is caused by the increase of the saturation water vapour.
Therefore, the humidity raises gradually after the temperature reaches the preset
temperature.
In the humidifying operation, the operation sound increases by about 2 dB both in the indoor
unit and outdoor unit. (When the airflow rate is in L or SL, the operation sound increases by
about 3 dB in the indoor unit.)
This system does not suppose the storage of musical instruments or the like.
