The unit case is manufactured with coated metal. Cold surfaces are covered with a coated polystyrene insulating material. The case is provided with metal ears designed to support the unit weight on four corners.

Ears have pre-punched holes designed to accept field-supplied all-thread rod hangers.

Ventilation Air TQ, TR Chassis The case has a factory designated cutout for the connection of a field-supplied outside air duct. An optional flange kit is available from LG. The outside air can supply only one ceiling cassette indoor unit.

TM, TN, TP Chassis The case has a factory designated cutout for the connection of a field-supplied outside air duct. LG offers two flange kits. The outside air can supply only one ceiling cassette indoor unit.

Supply Air Branch Duct Connections Factory designated cutouts are marked on the unit case. Branch ducts provide the designer with the ability to duct up to ½ the unit airflow capacity to adjacent spaces. The adjacent space must be in the room where the ceiling cassette is installed. It cannot be branched to another room.

TQ, TR Chassis Connections can be made on up to any two of the three available connection points.

TM, TN, TP Chassis Connections can be made on up to any two of four available connection points.

Architectural Filter/Grille The ceiling cassette assembly is provided with an off-white ABS polymeric resin architectural grille equipped with a tapered trim edge and a hinged, spring clip (screwless) return air filter-grille door.

TM, TN, TP Chassis The unit case allows access to hanger rods and the inspection of piping through corner access panels on the architectural grille. The optional auto-elevating grille kit is designed to provide motorized ascent/descent of the return air grille/pre-filter assembly a distance of up to 14-3/4 feet allowing easy access to remove and clean the filter.

The kit consists of two lifting mechanisms comprised of an electric motor driven winch with braided steel lifting cables. The winch kit is mounted behind the grille and is not visible during normal unit operation. The auto-elevating return air grille appearance and finish matches that of the architectural grille on similar indoor unit models equipped with the standard hinged filter grilles. The auto-elevating grille control algorithm accepts up, down, and stop control commands from either a wall-mounted or the lift remote controller.

The algorithm does not permit the lowering of the grille while the indoor unit fan is operating. The pair of winch controllers work in unison to keep the return air grille level during lift and descent operations and will automatically stop the descent of the return air grille/filter if contact is made with any obstacle.

Fan Assembly and Control The indoor unit has a single, direct-drive, turbo fan. The fan wheel is made of high strength ABS HT-700 polymeric resin. The fan motor is a Brushless Digitally-Controlled (BLDC) design with permanently lubricated and sealed ball bearings. The fan/motor assembly is mounted on vibration attenuating rubber grommets. The fan speed is controlled using a microprocessor-based, direct digital control algorithm that provides a minimum of four pre-programmed fan speeds in the Heating and Fan Only modes and five speeds in the Cooling mode. Fan settings are super high, high, medium, and low.

Each setting can be field adjusted from the factory speed setting (RPM/ESP) to compensate for a limited amount of additional resistance to airflow caused by field connected ductwork or other airflow restricting devices. The fifth speed in the Cooling mode is a fan power cooling cycle that runs for 30 minutes at high fan speed. A chaos setting provides a random change in fan speed. The fan speed algorithm provides a field selectable, fixed-speed or auto-speed setting that adjusts the fan speed based on the difference between the controller set-point and space temperature.

Air Filter Return air is filtered with a removable, washable filter. The unit is also equipped with a plasma filter.

Airflow Guide Vanes The architectural grille has four-directional slot diffusers each equipped with independent oscillating motorized guide vanes designed to change the angle airflow is discharged. Discharge range

of motion is 40° in an up/down direction. The unit has a guide vane control algorithm designed to sequentially change the predominant discharge airfl ow direction in a counterclockwise pattern. The control algorithm also provides the capability of locking each guide vane independently in a fi eld adjusted fi xed position. Guide vanes provide airfl ow in all directions. The ends of each vane are tapered to provide airflow to the space in the direction of the four corners of the architectural grille.

Microprocessor Controls The unit is provided with an integrated microprocessor controller capable of performing functions necessary to operate the system without the use of a wall-mounted controller. A temperature thermistor is factory-mounted in the return air stream. All unit operation parameters, excluding the unit operating schedule, are stored in non-volatile memory resident on the unit microprocessor.

Operating schedules are stored in select models of the optional, wall-mounted, local, or central controller. The field-supplied communication cable between the indoor unit(s) and outdoor unit is to be a minimum of 18 AWG, 2 conductor, stranded, and shielded cable (RS485), terminated via screw terminals on the control boards.

The microprocessor control algorithms provide the following functions: self-diagnostics, auto restart following power restoration, test run, and will operate the indoor unit using one of five operating modes:

1. Auto Changeover (Heat Recovery only)

2. Heating

3. Cooling

4. Dry

5. Fan Only For Heat Recovery systems the Auto Changeover setting automatically switches control of the indoor unit between cooling and heating modes based on space temperature conditions.

For Heat Pump systems, heated or cooled air delivery is dependant upon outdoor unit operating mode.

In Heating mode, the microprocessor control will activate indoor unit operation when the indoor room temperature falls below setpoint temperature. At which point, a signal is sent to the outdoor unit to begin the heating cycle. The indoor unit fan operation is delayed until coil pipe temperature reaches 76ºF. Significant airflow is generated when pipe temperature reaches 80°F. The unit is equipped with an infrared receiver designed to communicate with an LG hand-held remote controller. In lieu of wireless remote or factory return air thermistor, pluggable connection sockets on the microprocessor circuit board accommodate various models of wall-mounted local controllers and/or a wall-mounted remote temperature sensor. The unit microprocessor is capable of accepting space temperature readings concurrently or individually from either:

1. Wall-mounted wired controller(s)

2. Factory mounted return air thermistor or the optional wall-mounted wired remote temperature sensor .

A single indoor unit has the capability of being controlled by up to

The microprocessor controls space temperature using the value provided by the temperature sensor sensing a space temperature that is farthest away from the temperature set-point. The microprocessor control provides a cooling mode test cycle that operates the unit for 18 minutes without regard to the space temperature. If the system is provided with an optional wall-mounted, local, or central controller, displayed diagnostic codes are specifi c, alpha numeric, and provide the service technician with the reason for the code displayed.

Condensate Lift/Pump The indoor unit is provided with a factory installed and wired condensate lift/pump capable of providing a minimum 27.5 inch lift from the bottom surface of the unit. The lift pump comes with a safety switch that shuts off the indoor unit if condensate rises too high in the drain pan.
