OPERATIONS (Cont.)
SLEEP MODE
Use this mode to reduce operation sound while sleeping.
• Press the SLEEP button once and air flow sound from the indoor unit will be decreased.
• Press the SLEEP button again to turn Sleep mode off.
NOTE:
• Use sleep mode when you are going to bed. If this mode is used during the day,
the functionality may be reduced due to the ambient temperature being too high.
• During operation of cooling mode, the room temperature setting will be raised
gradually by 2°C higher than the set temperature once the unit is in sleep mode.
• During operation of heating mode, the room temperature setting will be dropped
gradually by 5°C lower than the set temperature once the unit is in sleep mode.
OPERATIONAL PRINCIPLES OF HEATING MODE
• The unit absorbs heat from the outdoor air and transfers it indoors to heat the room air.
The heating capabilities through this principle of heat pumping alters with the variations
of temperature of the outdoor air.
• It will only take a short amount of time for hot air circulation to raise the room temperature.
• If the temperature outdoors is extremely low, this system can be used together with
other heating devices, as long as good ventilation is provided.
Defrosting
When the outdoor temperature is very low, and the humidity is very high, frosting will
occur due to the heat exchange of the outdoor unit, which can have negative impacts on the
efficiency of the heating performance. In such cases, the automatic defrosting function will
come into play.
The heating operation will be stopped for 5-10 minutes to do the defrost.
• The fans of both indoor and outdoor units will stop.
• During defrosting, the outdoor unit may product steam. This is caused by rapid
defrosting and is not a performance failure.
• Upon completion of the defrosting process, heating operations will resume.
