LG Air Conditioner Technical Solution (LATS) SoftwareA properly designed and installed refrigerant piping system is critical to the optimal performance of LG air-conditioning systems. To assist engineers, LG offers, free of charge, LG Air Conditioner Technical Solution (LATS) software—a total design solution for LG air conditioning systems.

To reduce the risk of designing an improper applied system or one that will not operate correctly, LG requires that LATS software be used on all projects.

FormatsLATS is available to LG customers in three user interfaces: LATS HVAC, LATS CAD2, and LATS REVIT. All three LATS formats are available through www.myLGHVAC.com, or contact an LG Sales Representative.

LATS HVAC is a Windows®-based application that aids engineers in designing LG Variable Refrigerant Flow (VRF), Multi F / Multi F MAX, Single-Zone, and Energy Recovery Ventilator (ERV) systems.*Windows® is a registered mark of Microsoft® Corporation.

LATS CAD2 combines the LG LATS program with AutoCAD® software**. It permits engineers to layout and validate LG Multi V Variable Refrigerant Flow (VRF), Multi F / Multi F MAX, Single-Zone, and Energy Recovery Ventilator (ERV) systems directly into CAD drawings.

LATS Revit integrates the LG LATS program with Revit® software**. It permits engineers to layout and validate Multi V VRF systems directly into Revit drawings.**AutoCAD® and Revit® are both registered marks of Autodesk, Inc.

FeaturesAll LG product design criteria have been loaded into the program, making LATS simple to use: double click or drag and drop the com-ponent choices. Build systems in Tree Mode where the refrigerant system can be viewed. Switch to a Schematic diagram to see the electrical and communications wiring.LATS software permits the user to input region data, indoor and outdoor design temperatures, modify humidity default values, zoning, specify type and size of outdoor units and indoor units, and input air flow and external static pressure (ESP) for ducted indoor units.

The program can also:

LG AIR CONDITIONER TECHNICAL SOLUTION (LATS)

• Import building loads from a separate Excel file.• Present options for outdoor unit auto selection.• Automatically calculate component capacity based on design

conditions for the chosen region.• Verify if the height differences between the various system

components are within system limits.• Provide the correct size of each refrigerant piping segment and LG

Y-Branches and Headers.

• Adjust overall piping system length when elbows are added.• Check for component piping limitations and flag if any parameters

are broken.• Factor operation and capacity for defrost operation.• Calculate refrigerant charge, noting any additional trim charge.• Suggest accessories for indoor units and outdoor units.• Run system simulation.

Features depend on which LATS program is being used, and the type of system being designed.

LATS Generates a Complete Project ReportLATS software also generates a report containing project design parameters, cooling and heating design data, system component perfor-mance, and capacity data. The report includes system combination ratio and refrigerant charge calculations; and provides detailed bill of material, including outdoor units, indoor units, control devices, accessories, refrigerant pipe sizes segregated by building, by system, by pipe size, and by pipe segments. LATS can generate an Excel GERP report that can imported into the LG SOPS pricing and ordering system.

Proper Design to Install ProcedureLG encourages a two report design-to-install-procedure. After the design engineer determines building / zone loads and other details, the engineer opens the LATS program and inputs the project’s infor-mation. When the design is complete, the “Auto Piping” and “System Check” functions must be used to verify piping sizes, limitations, and if any design errors are present. If errors are found, engineers must adjust the design, and run Auto Piping and System Check again. When the design passes the checks, then the engineer prints out a project “Shop Drawing” (LATS Tree Diagram) and provides it to the installing contractor. The contractor must follow the LATS Tree Diagram when building the piping system, but oftentimes the design changes on the building site:

• Architect has changed location and/or purpose of room(s).• Outdoor unit cannot be placed where originally intended.• Structural elements prevent routing the piping as planned.• Air conditioning system conflicts with other building systems

(plumbing, gas lines, etc.).

The contractor must mark any deviation from the design on the Shop Drawing, including as-built straight lines and elbows. This “Mark Up” drawing must be returned to the design engineer or Rep, who must input contractor changes into the LATS file. (Copy the original LATS soft-ware file, save and rename as a separate file, and modify all piping lengths by double-clicking on each length and editing information.) Like the shop drawing, the Auto Piping and System Check must also be run on this new “As Built” drawing. The design engineer or Rep must then provide the final As Built file to the contractor. The Mark Up version must be compared to the As Built version for:

• Differences in pipe diameter(s). If incorrect diameters have been installed, the piping must be changed out. If pipe diameters have changed,check to see if Y-Branches will also need to be changed.

• Changes to outdoor unit and indoor unit capacities. Capacities changes may impact line length changes.• Additional refrigerant charge quantity (“Trim Charge”). Trim charge will change if piping lengths and diameters change. The As Built version

must reflect installed piping lengths to ensure correct trim charge.

All documents submitted by the contractor, as well as the Shop Drawing and the As Built Drawing files must be provided for commissioning purposes. Model and serial numbers for all system components must also be submitted. If the steps previously detailed are not followed, and all documents are not provided to the commissioning agent, the project runs the risk of not being commissioned and voiding any limited warranty LG offers on the equipment.

CasingThe case is designed to mount recessed in the ceiling and has a surface-mounted concentric grille on the bottom of the unit. 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 AirThe case has a factory designated cutout for the connection of a field-supplied outside air duct and flange.

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

Fan Assembly and ControlThe indoor unit has a single, direct-drive, cross-flow tangential Sirocco fan made of high strength ABS GP-2305 polymeric resin. The fan motor is a Brushless Digitally Controlled (BLDC) design with permanently lubricated and sealed ball bearings. The fan motor in-cludes thermal, overcurrent and low RPM protection. The fan / motor assembly is mounted on vibration attenuating rubber grommets. The fan impeller is statically and dynamically balanced. The fan speed is controlled using a microprocessor-based control algorithm that provides a high fan speed in cooling thermal ON and low fan speed in cooling thermal OFF, high fan speed in heating thermal ON and fan off in heating thermal OFF. The fan speeds can be field adjusted between low, medium, and high speeds. The fan speed algorithm provides a field-selectable fixed-speed or auto-speed setting that adjusts the fan speed to simulate natural airflow.

Air FilterReturn air is filtered with a removable, washable filter with anti-fungal treatment. Plasma filter accessories are also available separately.

Airflow Guide VanesThe architectural grille has a single directional slot diffuser with an oscillating motorized guide vane designed to change the angle airflow is discharged. The discharge range of motion is 40º in an up/down direction with the capability of locking the vanes in a field adjusted fixed position.

Microprocessor ControlsThe 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 operation 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, twisted, stranded, and shielded cable (RS-485), terminated via screw terminals on the control boards. The microprocessor control provides the following functions: auto addressing, 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. Heating3. Cooling4. Dry5. Fan Only

For Heat Recovery systems the Auto Changeover setting automati-cally 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 dependent upon outdoor unit operating mode. In Heating mode, the microprocessor control will activate indoor unit operation when the indoor room temperature falls below set-point 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 wireless remote controller. In lieu of wireless remote or factory return air thermistor, screw terminals on the microprocessor circuit board ac-commodate 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 two local wired controllers. The microprocessor controls space tem-perature 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 or heating

CasingThe case is designed to mount recessed in the ceiling and has a surface-mounted concentric grille on the bottom of the unit. The unit case is manufactured with coated metal, and 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-sup-plied, all-thread rod hangers.

Ventilation AirThe case has a factory designated cutout for the connection of a field supplied outside air duct.

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

Fan Assembly and ControlThe 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 includes thermal, overcurrent and low RPM protection. The fan / motor assembly is mounted on vibration attenuating rubber grommets. The fan impeller is statically and dynamically balanced. The fan speed is controlled using a microprocessor-based direct digital control algorithm that provides a high fan speed in cooling thermal ON and low fan speed in cooling thermal OFF, high fan speed in heating thermal ON and fan off in heating thermal OFF. The fan speeds can be field adjusted between low, medium, and high speeds. The fan speed algorithm provides a field selectable, fixed-speed or auto-speed setting that adjusts the fan speed to simulate natural airflow.

Air FilterReturn air is filtered with a removable, washable filter with anti-fun-gal treatment.

Airflow Guide VanesThe architectural grille has two parallel directional slot diffusers each equipped with oscillating motorized guide vanes designed to change the angle airflow is discharged. Discharge range of motion is 40º in an up/down direction. The control algorithm provides the capability of locking guide vanes in a field adjusted fixed position.

Microprocessor ControlsThe unit is provided with an inte-grated microprocessor controller capable of performing functions necessary to operate the system without the use of a wall-mount-ed controller. A temperature thermistor is factory-mounted in the return air stream. All unit operation parameters, excluding the units 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, twisted, stranded, and shielded cable (RS 485), terminated via screw termi-nals on the control boards. The microprocessor control provides the following functions: auto addressing, self-diagnostics, auto restart following power restoration, test run, and will operate the indoor unit using one of five operating modes:


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 dependent upon outdoor unit operating mode. In Heating mode, the microprocessor control will activate indoor unit operation when the indoor room temperature falls below set-point 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 76°F. Significant airflow is generated when pipe temperature reaches 80°F. The unit is equipped with an infrared receiver designed to communicate with an LG wireless remote controller. In lieu of wireless remote or factory return air thermistor, screw terminals on the microprocessor circuit board accommodate various models of wall-mounted local controllers and or wall-mounted temperature sensors. 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 two local wired controllers. The microprocessor controls space tem-perature using the value provided by the temperature sensor sens-ing a space temperature that is farthest away from the temperature set-point. The microprocessor control provides a cooling or heating mode test cycle that operates the unit for 18 minutes without regard to space temperature. If the system is provided with an optional wall-mounted or central controller, displayed diagnostic codes are specific, alpha numeric, and provide the service technician with the reason for the code displayed.

Indoor units are Wi-Fi compatible with the addition of an LG Wi-Fi module accessory, and can be controlled by LG’s Smart ThinQ™ app on a smart device. A field-supplied Wi-Fi network and smart device are required. The Smart ThinQ app is free, and is available for Android™ and iOS. (Android is a trademark of Google LLC.)

CasingThe case is designed to mount recessed in the ceiling and has a surface-mounted concentric grille on the bottom of the unit. 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 AirTQ, TR FrameThe case has a factory designated cutout for the connection of a field-supplied outside air duct. An optional flange kit is available from LG.

TM, TN FrameThe case has a factory designated cutout for the connection of a field-supplied outside air duct. LG offers two flange kits.

Supply Air Branch Duct ConnectionsFactory designated cutouts are marked on the unit case. Branch ducts provide the designer with the ability to duct up to 1/2 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.

Architectural Filter/GrilleThe 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 FrameThe 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 com-mands 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 ControlThe 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 includes thermal, overcurrent and low RPM protection. The fan/motor assembly is mounted on vibration attenuating rubber grommets. The fan impeller is statically and dynamically balanced. The fan speed is controlled using a microprocessor-based, direct digital control algorithm that provides a high fan speed in cooling thermal ON and low fan speed in cooling thermal OFF, high fan speed in heating thermal ON and fan off in heating thermal OFF. The fan speeds can be field adjusted between low, medium, and high speeds. The fan speed algorithm provides a field selectable, fixed-speed or auto-speed setting that adjusts the fan speed to simulate natural airflow.

Air FilterReturn air is filtered with a removable, washable filter with anti-fungal treatment. Plasma filter accessories are also available separately.

Airflow Guide VanesThe architectural grille has four-directional slot diffusers each equipped with independent oscillating motorized guide vanes de-signed 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 predomi-nant discharge airflow direction in a counterclockwise pattern. The control algorithm also provides the capability of locking each guide vane independently in a field adjusted fixed position. Guide vanes provide airflow 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 ControlsThe 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 therm-istor 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, twisted, stranded, and shielded cable (RS-485), terminated via screw terminals on the control boards. The micro-processor control algorithms provide the following functions: auto addressing, self-diagnostics, auto restart following power restoration, test run, and will operate the indoor unit using one of five operating modes:


For Heat Recovery systems the Auto Changeover setting automati-cally 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 dependent 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 76°F. Significant airflow is generated when pipe temperature reaches 80°F. The unit is equipped with an infrared receiver designed to communicate with an LG wireless remote controller. In lieu of wireless remote or factory return air thermistor, screw terminals on the microprocessor circuit board ac-commodate 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 two local wired controllers. The microprocessor controls space tem-perature 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 or heating 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 specific, alpha numeric, and provide the service technician with the reason for the code displayed.

The indoor units are Wi-Fi compatible with the addition of an LG Wi-Fi module accessory, and can be controlled by LG’s Smart ThinQ™ app on a smart device. A field-supplied Wi-Fi network and smart device are required. The Smart ThinQ app is free, and is available for Android™ and iOS. (Android is a trademark of Google LLC.)

General Drain Piping InformationAll ceiling-cassette indoor units generate water during cooling operation, therefore, properly handling this condensation must be considered. Ceiling-cassette indoor units include factory-installed drain pumps. Depending on the location of the indoor unit, condensation can be drained directly to the outside of the building, or a common indoor unit drainage piping system can be installed.

APPLICATION GUIDELINESGeneral Drain Piping Information

Ensure the indoor unit, refrigerant piping, drain piping, and power wiring / communication cables are properly supported with anchor bolts and clamp hangers positioned at 3.3 to 4.9 foot intervals.

Figure 93: Example of a Common Indoor Unit Drainage System.

Drain Piping• Drain piping must have down slope (1/50 to 1/100). • Any holes through the ceilings, walls, etc., must be large enough to accom-

modate the drain piping and insulation.• The outside diameter of the drain connection on the indoor unit is 1-1/4

inches.• Drain piping material is polyvinyl chloride pipe (1 inch).

Drain Leak TestA leak test must be performed 24 hours after the drainage system has been installed.

Drain Pipe InsulationInstall field supplied polyethylene foam insulation 5/16 inch thick or greater on the flexible drain pipe and position snugly again indoor unit.

Common Indoor Unit Drainage SystemIt is usual work practice to connect individual indoor unit drain pipes to one common indoor unit drainage system.

The diameter of the common vertical drain pipe must be as large as necessary. The diameter of the horizontal pipe must be the same or larger than the vertical drain pipe. To avoid property damage in the event of the primary drain becom-ing clogged, and to optimize drain system perfor-mance, it may be prudent to install a secondary drain line.

Design the drain system to plan for winter opera-tion (condensate line may freeze up if condensate does not properly drain away). Drain all gener-ated condensate from the external condensate pan to an appropriate area. Install a trap in the condensate lines as near to the indoor unit coil as possible. To prevent overflow, the outlet of each trap must be positioned below its connection to the condensate pan. All traps must be primed, insulated, and leak tested.

• It is recommended that a dedicated drain pipe be installed for the air conditioning sys-tem. If the indoor unit drainage system is shared with a rainwater drain, waste water, or any other type of building drain system, back flow, leaks, ice may form, or noxious odors may infiltrate the air conditioning system.

• Install a trap if the drain access to the outside faces an undesirable location (i.e.,

Flexible Drain Hose, continued.When the receiving drain line is mounted horizontal, connect the inverted trap to the top half of the pipe. The connection point of the inverted trap to the building drain pipe must always be to the top half of the pipe and must never be over 45° either side of the upper most point of the horizontal building drain line.

APPLICATION GUIDELINESWiring Guidelines

Connecting the Power Wiring / Communication CableDANGE

High voltage electricity is required to operate this system. Adhere to the National Electrical Codes and these instructions when wiring. Always ground the unit following local, state, and National Electrical Codes. Read the safety summary at the begin-ning of this manual.• Secure all field wiring connections with appropriate wire strain relief. Improperly securing wires will create undue stress on equipment power

lugs. Inadequate connections will generate heat, cause a fire and physical injury or death.• Properly tighten all power connections. Loose wiring will overheat at connection points, causing a fire, physical injury or death.

• Connect the indoor unit input power cable but do not apply power to the indoor unit until authorized to do so by the system commission-ing agent. Inappropriate power connection can result in equipment damage and will void the LG limited liability warranty.

• -cal path or route the wire takes. The installer can use discretion when choosing the order the components are connected to the communica-tions bus, but must maintain the daisy chain and polarity configuration.

• Failure to follow any of these power and communications wiring guidelines or instructions will cause communications errors and unit mal-function.

Do Not’s• Never use wire caps and never splice communications cables.• Never connect zone controllers or other central controllers or LG building management system gateways to the indoor unit / outdoor unit

communications cable.

Connection ProcedureIndoor unit installation best practices are to connect control wiring (low voltage) and then connect power wiring (high voltage). Do not apply power to the indoor unit or any Multi V system component until authorized to do so by the system commissioning agent.

1. Ensure the input power is disconnected and there is no power on the power input cable.

2. Remove the knock-out plugs from the control box. Remember the communications cable and the power cable must enter the control box through different knockouts.

3. Field-install a plastic or rubber grommet in the knockout holes to prevent wire chaffing.

4. If using conduit, connect the conduit to the control box using field-provided fittings and industry best-practice procedures.

5. Separately route the power wiring and communications cables to the unit’s terminal block (see figures on the following pages). Do not route the communications cable near the power cable. Two-way and four-way cassettes feature wiring and cable paths on opposites side of the indoor unit. Provide at least three (3) to four (4) inches of slack cable at each indoor unit.

6. Connect the power wiring to the terminal block connections. Ensure the screws securely connect the wire to the terminals and are not loose.• For One-Way Cassettes: Terminal Block 1(L1) and 2(L2) connections.• For Two-Way and Four-Way Cassettes: Terminal Block L(L1) and N(L2) connections.

7. Connect the field-provided communications cable to the 3(A) and 4(B) terminal block connections. Polarity matters on the outdoor unit to indoor unit / heat recovery unit communications bus, and must be maintained throughout the entire system. Be sure to connect 3(A) terminals to A terminals and 4(B) terminals to B terminals. Refer to the next pages for indoor unit wiring connections, the Outdoor Unit Installation Manual for information regarding the outdoor unit and heat recovery unit wiring connections, or review the wiring diagrams on the applicable units.

• • Field-provided communication cable between Master ODU to IDUs / HRUs to be 18 AWG, 2-conductor, twisted, stranded, shielded. Ensure

the communication cable shield is properly grounded to the Master ODU chassis only. Do not ground the ODU to IDUs / HRUs commu-nication cable at any other point. Wiring must comply with all applicable local and national codes.

8. If a remote controller is to be installed, connect the remote controller’s cable to the indoor unit’s remote controller connection. Controller connections depend on type of indoor unit being installed. Some indoor units use terminal block connections; other indoor units use Molex connections. See the wiring diagram for each specific indoor unit.

9. Connect any additional cables required for the installation such as those for the decoration panels.

Wired Controller PlacementWired controllers include a sensor to detect room temperature. To maintain comfort levels in the conditioned space, the wired controller must be installed in a location away from direct sunlight, high humid-ity, and where it could be directly exposed to cold air. Controller must be installed four (4) to five (5) feet above the floor where its display can be read easily, in an area with good air circulation, and where it can detect an average room temperature.

Do not install the wired controller near or in:• Drafts or dead spots behind doors and in corners

• Hot or cold air from ducts

• Radiant heat from the sun or appliances

• Concealed pipes and chimneys

• An area where temperatures are uncontrolled, such as an outside wall
