6RWU0-03A Features
Infinite Impulse response (IIR)
The IIR function senses the temperature several times per second and make micro adjustments accordingly.
Compressor Restart Delay
This feature extends the overall life of the compressor by preventing the short cycling of the air-conditioner. When the com-
pressor restarts, LG PTAC is designed to give it a minimum of three minutes to have a time of equalizing the refrigerant
pressures for optimizing the cycle.
Fan only setting
When the Fan only setting is made, only the fan on the indoor side operates while the compressor stops operating and the
unit ceases to run in the Cooling or the Heating mode.
Indoor Fan speed setting
The Indoor fan can run at HIGH or LOW speed for either COOLING or HEATING operation.
Two Fan motors
The air conditioning unit has two fan motors for providing a quiet operation and maximum efficiency.
LED Diagnostics and Self Diagnostics
LED Diagnostics feature indicates the problem by its easy to read diagnostics, when the unit does not operate properly. For
example, one blink every 2 seconds indicate compressor failure.
While Self Diagnostics feature is used in micom models and it indicates the problem by a displaying a set of error codes.
2 position discharge grille
The discharge grille can provide air flow upwards at an angle of 40˚ off vertical or 15˚ off vertical. The angle is changed by
removing the front grille and 4 screws that fasten the discharge grille to the front grille and rotating the louvers to an alter-
nate position.
Indoor room freeze protection
When the unit senses the room temperature to be less than 40˚ F, the unit activates the fan motor and either the electric
resistance heater or the hydronic heater, to prevent the pipes or fixtures from freezing. This also overrides the front desk
control of the unit mounted controls or the 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 manage-
ment feature by checking whether any people are present inside the room or not. If there are no people inside the room, the
energy management feature is in play.
Compressor Overload protection
This feature prevents damage of the compressor by sensing the indoor coil temperature during the heating mode. If the
indoor coil temperature is over 130˚ F, the outdoor fan is switched off and it operates again only when the temperature
drops below 120 ˚ F.
