DR Control (Demand Response Capability)

This product is designed to be compatible with your Energy Supplier’s Demand
Response Control Program (if implemented). If you are taking part in this
program, the Energy Supplier’s Demand Control Signal Receiver (DCSR), will be
installed in your system outdoor unit by your installer.
If a Demand Response signal is received from your energy supplier, the power
consumption of your system will be reduced depending on the signal mode
received.
During a Demand Response period, the indoor unit display area will display d1, d2
or d3. Please see table below for details of each mode.

DR m ode

DR m ode 1 Co mpr es sor o ff.

DR m ode 2

DR m ode 3

De scr ipt ion of op era tion in this m ode

The air conditioner continues to cool or heat during the demand response event, but the total electrical energy (kWh) consumed
by the air conditioner in a half hour period is not more than 50% of the total electrical energy that would be consumed in a half
hour period during normal operation under the same temperature and humidity conditions, and the same user settings.

The air conditioner continues to cool or heat during the demand response event, but the total electrical energy (kWh) consumed
by the air conditioner in a half hour period is not more than 75% of the total electrical energy that would be consumed in a half
hour period during normal operation under the same temperature and humidity conditions, and the same user settings.

If a DR signal input malfunction occurs the display area will display dE and the system
will operate normally. When the system is in a DR mode, the cooling or heating effect
of the system may be slightly reduced.

Common Issues

The following problems are not a malfunction and in most situations will not require repairs.

Issue Possible Causes

Unit does not turn
on when pressing
ON/OFF button

The unit changes
from COOL/HEAT
mode to FAN
mode

The indoor unit
emits white mist

Both the indoor
and outdoor units
emit white mist

The Unit has a 3-minute protection feature that prevents the
unit from overloading. The unit cannot be restarted within
three minutes of being turned off.

The unit may change its setting to prevent frost from forming
on the unit. Once the temperature increases, the unit will start
operating in the previously selected mode again.

The set temperature has been reached, at which point the
unit turns off the compressor. The unit will continue operating
when the temperature fluctuates again.

In humid regions, a large temperature difference between the
room’s air and the conditioned air can cause white mist.

When the unit restarts in HEAT mode after defrosting, white
mist may be emitted due to moisture generated from the
defrosting process.

Troubleshooting

 Page 14 

Issue Possible Causes

A rushing air sound may occur when the louvre resets
its position.

The indoor unit
makes noises

A squeaking sound may occur after running the unit in HEAT
mode due to expansion and contraction of the unit’s plastic
parts.

Low hissing sound during operation: This is normal and is
caused by refrigerant gas flowing through both indoor and
outdoor units.

Both the indoor
unit and outdoor
unit make noises

The outdoor unit
makes noises

Dust is emitted
from either the
indoor or outdoor
unit

The unit emits a
bad odor

Low hissing sound when the system starts, has just stopped
running, or is defrosting: This noise is normal and is caused by
the refrigerant gas stopping or changing direction.

Squeaking sound: Normal expansion and contraction of
plastic and metal parts caused by temperature changes during
operation can cause squeaking noises.

The unit will make different sounds based on its current
operating mode.

The unit may accumulate dust during extended periods of
non-use, which will be emitted when the unit is turned on.
This can be mitigated by covering the unit during long periods
of inactivity.
