Operation tips
Cooling Operation
Principle
Air conditioners absorb heat from the room and transmit it to the
outdoor unit, so that the room temperature is decreased. The
cooling capacity will increase or decrease according to the outdoor
ambient temperature.
Antifreezing Function
If the unit is operating in COOL mode and in low ambient
temperature, frost may be formed on the heat exchanger. When
indoor heat exchanger temperature decreases below zero,
compressor will stop operation to protect the unit.
Heating Operation
Principle
Air conditioners absorb heat from outdoors and transmit it
to the indoor unit, increasing the indoor room temperature. The
heating capacity will decrease at low ambient temperature.
Defrosting
When outdoor temperature is low but humidity is high, ice may
form on the outdoor unit during extended operation, affecting
the heating efficiency. The air conditioner may stop operation
during an auto defrosting operation to remove this ice. During
auto defrosting, the fan motors of indoor unit and outdoor unit
will stop. During defrosting, the indoor indicator flashes “H1” and
the outdoor unit may emit water vapor. This is not a malfunction.
After defrosting is finished, the heating operation will recover
automatically.
Anti-cold Air Function
In HEAT mode, the indoor fan will not operate in order to prevent
cold air being blown into the room (within 2 minutes). If the indoor
heat exchanger doesn't reach a minimum temperature under the
following three states:
1
Heating operation starts;
2
After Auto Defrosting is finished;
3
Heating at low temperature.
Gentle Breeze
In the following situations, the indoor unit may blow a gentle
breeze, and the horizontal louver rotates to a certain position:
1
In HEAT mode, the compressor does not start operation after
the unit is turned on.
2
In HEAT mode, the temperature reaches the setting value and
the compressor has stopped operation for about 1 minute.

Tips for energy saving
•
Do not overcool or overheat. Setting temperature at a
moderate level helps energy saving.
•
Cover windows with a blind or a curtain. Blocking sunlight and
air from outdoors reduces energy consumption.
•
Clean air filters every 3 months. Clogged air filters lead to
inefficient operation and energy waste.
Tip for relative humidity
Condensate water is likely to form at the air outlet if cooling or
drying for a long time when the relative humidity is more than 80%
(with doors and windows open).
Demand Response
•
This unit is Demand Response - enabled. This means it can
be interfaced with your electricity supplier to utilise Demand
Response if available. A separate arrangement needs to be
made for this. Contact your energy supplier to determine
if there is an Air Conditioning Demand Response program
available in your area
•
When your energy supplier activates one of the 3 possible
Demand Response modes, the display of the indoor unit will
show d1, d2 or d2 as described below:
Demand response
mode
Description of operation
in this mode
d1
Compressor off
d2
The air conditioner continues to
cool or heat during the demand
response event,but the electrical
energy consumed by the air
conditioner in a half your period is
not more than 50% of the total
electrical energy that would be
consumed if operating at the rated
capacity in a half hour period.
d3
The air conditioner continues to
cool or heat during the demand
response event, but the electrical
energy consumed by the air
conditioner in a half your period is
not more than 75% of the total
electrical energy that would be
consumed if operating at the rated
capacity in a half hour period.
•
When the unit goes into a Demand Response mode,
the effect of cooling or heating may be reduced, the unit will
run as designed. You can not reverse this function by remote
control by change setting temperature or other actions unless
the unit finishes the function.
•
Refer to your electricity supplier if you have problems with
the operation of the Demand Response Modes of your Air
Conditioner.
