Remote Controller Features

The remote controller comes with a FOLLOW ME feature which allows the remote controller to act as a

thermostat. This allows the unit to sense the temperature at the location of the remote controller, rather

than sensing the temperature at the indoor unit. The indoor unit is installed high on a wall, thus the ther-

mostat on the remote controller will provide a more accurate temperature reading for the room. Consult

the remote controller manual for more information.

Displayed when TURBO function is selected in

cooling or in heating modes. This air conditioner

is equipped with an ionizer, which generates

ions to remove microscopic particles from the air.

Rooms become healthier for those suffering from

asthma or allergies with the use of this feature.

DIGITAL DISPLAY

See chart below for operating conditions:

Operating Conditions:

When cooling is needed year round, including when outdoor temperatures are apt to fall below freezing, our

V Series inverter driven ductless mini-split systems will continue to work, as they come with factory installed

low ambient controls. The low ambient feature works by regulating the head pressure by varying the amount of

air ow through the condenser, which helps to prevent evaporator freeze ups and low pressure problems due to

low ambient outdoor temperatures. Low ambient operation is a great feature for temperature/humidity sensitive

environments or applications such as server/computer rooms, supermarkets, restaurants, or cooling tower fans.

Additionally, a crank case heater is required and factory installed, as it is needed for use with the low ambient

controls. The crank case heater minimizes liquid refrigerant migration to the compressor when the compressor

is not operating and helps to keep the compressor oil warm enough so that it remains uid to prevent slugging.

Crank case heaters also assist to greatly reduce heat loss to ambient air. Together, the lower ambient feature

combined with the factory installed crank case heater, will not only allow the air conditioner to cool year round,

but will also prevent compressor failure in low ambient conditions.

Manual Operation:

Manual operation can be used temporarily to run the unit without using the remote controller. This feature can

also be used to test the unit during installation and troubleshooting by an authorized service technician.

NOTE: This manual does not include Remote Controller Operations, see the <<Remote Controller Manual>>

packaged with the unit for details.

OPERATING MODES

AUTO operation

• When you set the air conditioner to AUTO mode, it will automatically select

cooling, heating (heat pump models only), or fan only operation depending

on what temperature you have selected and the actual room temperature.

• The air conditioner will control room temperature automatically around

the temperature set point you select.

• If the AUTO mode is uncomfortable, you can change desired tempera-

ture settings manually.

ECONOMY/SLEEP operation

• When you push ECONOMY button on remote controller it activates

SLEEP mode. During cooling, heating (heat pump only), or AUTO op-

eration, the air conditioner will automatically increase (cooling) or de-

crease (heating) 2°F (1°C) per hour.

• The set temperature will become steady 2 hours later.

• The SLEEP mode will turn off after 7 hours and revert back to the previ-

ous settings.

• The fan speed will be automatically controlled.

• This feature can maintain the most comfortable temperature and save

more energy during use.

DRY MODE/DEHUMIDIFYING operation:

• The temperature is regulated while dehumidifying by repeatedly turning

on and off of the cooling operation or fan only. The fan speed will be au-

tomatically controlled. In this mode, if the room temperature is lower than

50°F (10°C) the compressor will stop. The compressor will restart when

the room temperature is above 54°F (12.2°C).

Optimal Usage Tips:

To achieve optimal performance, please note the following:

• Adjust the air ow direction correctly so that it is not directed directly

blowing on people/animals.

• Adjust the temperature to achieve the highest comfort level. Do not ad-

just the unit to excessive temperature levels.

• When in COOL or HEAT modes close any open doors and windows within

the room that the unit is operating in to increase performance.

• Use TIMER ON button on the remote controller to select a time you want

to start your air conditioner.

• Do not put any objects near air inlet or air outlet, as the efciency of the

air conditioner may be reduced and the air conditioner may stop running

due to air ow blockages.

• Clean the air lter periodically, otherwise performance may be reduced.

• Do not operate unit with louvers in a closed position

• SUGGESTION: For units with an electric heater, when the outside

ambient temperature is below 32°F (0°C), we strongly recommend that

you keep the unit powered on in order to guarantee it runs smoothly.
