Unit Features

The PTAC has many features, some of which are different than those found on conventional PTAC units. The servicer must be

familiar with these features in order to

properly service the unit.

• Highly featured Micom controls using IIR (infinite impulse response)

IIR function can make Micom controls maximize and keep the comfort conditions to sense the small changes in temperature

per second.

• Compressor Restart delay

This feature extends the overall life of compressor by preventing the short-cycling of the air-conditioner. When the

compressor restarts, LG PTAC is designed to give a minimum of three minutes to have a time of equalizing the refrigerant

pressures for optimizing cycling.

• Fan-Only Setting - High/Low

The unit provides the function of selecting the either High or Low speed for Fan-Only operation.

• Indoor Fan Speed Selections - High/Low

The unit is operated in High-Heat or Low-Heat or High Cool or Low Cool.

• Two Fan motors

The unit has two fan motors to provide the occupants with the quiet environment to enjoy the peaceful life and maximum

operating efficiency.

• LED Diagnostics

All units have this feature indicating the problem when the unit is not operating properly with easy -to-read diagnostics. For

example, 1 blink every 2 seconds indicates the compressor failure.

• Indoor Filters

The unit uses the two indoor filters easily slide in and out. The filters may be cleaned by washing and brushing without

removing the front grille.

• Rotary Compressor

The unit uses the rotary compressor for the quiet, reliable operation and prolong life.

• 2 Position Discharge Grille

The discharge grille can provide air flows upward at an angle of 40 off vertical or 80 15 degree off vertical. An angle is

changed by removing the front grille and 4screws that fasten the discharge grille to the front grille to rotate an alternate

position of the louvers.

• Indoor Room Freeze Protection

When the unit senses the room temperature falls to 40˚F below, the unit activates the fan motor and either the electric

resistance heater or the hydronic heater to prevent pipes or fixtures from freezing. This also overrides front desk control of the

unit mounted or wall mounted controls.

• Door Switch/Occupancy Sensor

The unit is capable of accommodating a field installed door switch and occupancy sensor to operate the energy management

feature. For additional information, refer to the Unit Operation section.

• Compressor Overload Protection

This feature prevents the damage of the compressor by sensing the indoor tube temperature in heating. If the indoor

temperature is over 130˚F, the outdoor fan will be switched off and on below 120˚F.
