(th-Tune can only be used with MULTI-TEC units and PGDx can only be used with MEGA-TEC units.) If only one wall-mounted air conditioner is being used, it can be matched with either the LC6000 or a PGD/ PGDx stand-alone display (if applicable). If more than one wall-mount unit is installed, the LC6000 controller must be matched with the air conditioning units. The wall-mount units are specifically engineered for equipment cooling applications. All three wall-mount models can be used together with one LC6000 controller but must be limited to the same model within each zone. NOTE: The LC6000 controller and MULTI-TEC, FUSION-TEC WR Series and MEGA-TEC wall-mount units are designed specifically to work together. The controller cannot run other brands of systems, nor can other controllers run the MULTI-TEC, FUSION-TEC WR Series or MEGA-TEC wall-mount units. They are a complete system, and must be used together.

WARNING Electrical shock hazard. Disconnect VAC power supplies before servicing. Failure to do so could result in electric shock or death. IMPORTANT: When working with circuit board components, Bard recommends the use of an anti-static wrist strap to prevent static electricity shorts to electronic controls. LC6000 Controller The LC6000 controller is part of this air conditioning system. It is used to control up to 14 wall-mount air conditioners from one controller. The microprocessor control provides an easy-to-read interface with large LCD graphical display. It provides control for redundancy for the structure and equal wear on all units. Conduit is recommended for all wiring. Route communication wiring and power supply wiring in their own separate conduits. The LC6000 controller is not weatherproof and is intended for use in a weathertight structure. IMPORTANT: When connecting this product from a remote location, ensure that the network connection is secure and reliable. Mounting the LC6000 Controller The dimensions of the LC controller are 16" x 12" x 6". Because the LC6000 controller utilizes a remote temperature sensor as opposed to one located in the controller box, the controller itself can be installed in any indoor location that is suitable, preferably at eye level. Four (4) mounting holes are provided for mounting to the wall and holes for conduit connections are provided in the base, sides and top of the controller. The LC6000 controller includes four fused power supply terminals in the terminal block. Before connecting wires to the terminal block, confirm that the fuse in each of the four fuse holders is in the proper position (active) as shown in Figure 2. FIGURE 2 LC6000 Fused Power Supply Terminals Fuse in Active Position Manual 2100-669J Page 6 of 43 Shipping Position Code: +07U0011EN Supply Wiring The LC6000 controller is powered by 120, 208 or 240 volts from the shelter. Field-supplied supply wiring should be minimum 16 gauge, maximum 14 gauge (see Figure 3). A reliable earth ground must be connected in addition to any grounding from conduit. Grounding bolts and nuts are included with the controller for this purpose; a 2 hole grounding lug must be field supplied. Install as shown in Figure 4. Failing to ground the controller box properly could result in damage to the equipment.

Failing to ground the controller box properly could result in damage to the equipment. Code: +07U0011EN Manual 2100-669J Page 7 of 43 Installing Remote Indoor Temperature/Humidity Sensor(s) One remote indoor temperature/humidity sensor and 35' of 18 gauge 5-conductor shielded cable is included with the controller. This sensor must be installed for proper operation. Mount the temperature/humidity sensor in a location least likely to be affected by open doors, rack-mounted fans, radiant heat sources, etc. Locating the sensor between both return grilles is often the best location, but every installation is unique. Location height should be approximately 60" above the floor. The sensor should be installed on a 2" x 4" junction box to allow for control wire conduit. Use shielded cable to connect to controller. The maximum cable length to connect the temperature/humidity sensor to the LC6000 is 98'. FIGURE 5 Remote Indoor Temperature/Humidity Sensor Installation 1.

The relay connections for the high indoor temperature 2 alarm are on the LC6000 terminal block; see Table 4 on page 33 for terminal block index. Emergency Off Alarm Operation The LC6000 has the capability of shutting down all unit functions in any or all zones from one input. A smoke detector or other device can be used to accomplish this. Terminals 6 and 7 are the terminal block connection points for this device. This input can be configured to accept either normally open or normally closed contacts. These are the contact positions when an event has occurred. The LC6000 is defaulted to normally open and shipped with a jumper between terminals 6 and 7. This jumper is to be removed when a device is added. The emergency off function can be enabled or disabled by zone. Resetting the control after an activation is also configurable by zone. Reset can be configured as "auto" meaning once the device contacts revert back to a safe state the units will be functional. Configuring as "user" will require a site visit to manually clear the alarm by holding the alarm icon for 3 seconds. Additionally there is a relay output that can be monitored remotely to provide notification of an event. Terminals 38 and 39 of the terminal block are for this option. The direction of these contacts can be changed from default of normally open to normally closed. NOTE: See Table 4 on page 33 for terminal block index. If an emergency off alarm is activated, the LC6000 status message will be "on" or other applicable status.

Code: +07U0011EN Manual 2100-669J Page 19 of 43 Emergency Vent Alarm Operation The LC6000 has the capability of signaling the units to ventilate a zone or zones when activated by a hydrogen detector or similar device. An alarm relay is also activated for remote notification. The ventilation input and the remote notification alarm output are both configurable as normally closed (factory default) or normally open. When a signal for emergency ventilation is activated, the units with economizers will open dampers 100% and the blowers will run at the highest available speed. Units without economizers will bring on the blowers at the highest available speed. FUSION-TEC WR units have a 45-second blower on delay when emergency ventilation is activated; this is a function of the unit. Emergency ventilation is overridden by emergency off. Emergency ventilation disables emergency cooling, economizer cooling, compressor cooling, heating and dehumidification. Emergency vent will not operate units that have been disabled during generator run. When an emergency ventilation event occurs, the LC6000 will have a status of "emer. vent.". The alarm key will be flashing red; when pushed, the alarm will be identified by zone as " emergency vent input active". Once the input has cleared the units will return to normal operation. The alarm key can be cleared by pushing and holding for 3 seconds; this must be done for each zone.

FIGURE 26 Rotation Demand The system will compare the zone temperature (determined by zone averaging selection) to the zone cooling and heating setpoint. A demand will be calculated to determine how many units are required. For cooling, the zone temperature will be compared to the cooling setpoint. The controller will calculate a demand based on how far above the setpoint and how long it has been above the setpoint. The demand value (0-100%) will then be split and applied to free cooling and cooling separately shown as two demands both ranged 0-100% applied to all of the available cooling methods for that zone. For example, if the demand is at 50% and there are 10 available stages of cooling in that zone, there would be 5 stages active (50% x 10 = 5). The system will prioritize free cooling stages over compressor stages. Adding to the example, if 5 of the 10 stages for cooling are economizer, 5 units would be running economizer and no compressors running. The demand is calculated for the cooling application. However, for display purposes, the demand is split so that the user can see demand separately for free cooling and compressor. For heating, the zone temperature will be compared to the heating setpoint. The controller will calculate a demand based on how far below the setpoint and how long it has been below the setpoint. The demand value 0-100% will the be applied to all of the available stages of heating in that zone. For example, if the demand is at 50% and there are 5 available stages of heating in that zone, there would be 2 stages active (50% x 5 = 2.5 and a half of a stage cannot be turned on). Humidity Control The LC can be configured to control up to three humidifiers (field supplied) with relay outputs and up to 14 units equipped with dehumidification. The indoor humidity level for each zone is compared to the dehumidification setpoint and humidification setpoint for each zone. Staged Dehumidification The supervisory controller will monitor the indoor relative humidity of each zone and compare the value of the setpoint of each mode. Below are the three modes available for dehumidification of each zone. Unit dehumidification options are determined by model number; all units in a zone must have the same dehumidification options. If communication is lost with the supervisory controller during a dehumidification call, dehumidification function will be ended and the unit will operate in orphan mode. Dehumidification Off When the humidity level inside a zone falls to the Dehumidification Off setpoint, the system will stop attempting to dehumidify the space. The default setpoint value for this mode is 60% RH. Passive Dehumidification When the humidity level rises to the Passive Dehumidification setpoint, the controller will activate staged dehumidification at the available wall units. As the humidity level rises to the passive dehumidification setpoint, the free cooling function (economizer) is disabled. When there is a call for cooling, the compressor will energize and the blower speed will be reduced to the unit dehumidification mode or Balanced Climate speed whichever is applicable to the unit. All units allowed to run within the zone will be given the dehumidification command and will operate as such on a call for cooling. The default setpoint value for passive dehumidification is 70% RH. Active Dehumidification When the humidity level rises to the Active Dehumidification setpoint, the supervisory controller will active staged dehumidification at the available wall units. The supervisory controller will then calculate the dehumidification demand based on how far above the setpoint and how long the RH level has been above the setpoint. The controller will then utilize all of the units with active dehumidification capabilities to reduce the indoor humidity level. The units will be staged on based on the existing cooling rotation for the units in Code: +07U0011EN Manual 2100-669J Page 25 of 43 the zone up to the maximum number of units allowed to run. When in demand minimum compressor run time is applicable, examples of demand are as follows: With two units with dehumidification capabilities, Unit 1 in rotation will come on at 50% demand and Unit 2 in rotation will come on at 100% demand. They will rotate off in a reverse; Unit 2 will be off at 50% demand and Unit 1 will be off at the dehumidification off setpoint. With three units with dehumidification capabilities, Unit 1 in rotation will come on at 33% demand, Unit 2 in rotation will come on at 67% demand and Unit 3 in rotation will come on at 100% demand. They will rotate off in reverse; Unit 3 will be off at 67% demand, Unit 2 will be off at 33% demand and Unit 1 will be off at dehumidification off setpoint. An active dehumidification sequence will run until the space temperature falls to the heating setpoint or increases to the cooling setpoint, or the dehumidification off setpoint is reached. Refer to the specific unit manual for active dehumidification sequence and space temperature control. The passive dehumidification setpoint must be lower than the active dehumidification setpoint to ensure the economizer is disabled during active dehumidification.

Always start sensor troubleshooting by verifying connections at the sensor board and at the LC6000 terminal blocks. Improper connection will cause inaccurate readings. Next, verify continuity at both ends of wires running between the sensor and the LC6000. A severed or damaged wire will cause inaccurate readings. As a last step, verify voltage and resistance at the sensor and the LC6000 terminal block per Tables 6 and 7 on pages 39 and 40. If the sensor is found to be malfunctioning, replace the sensor.

Earlier versions of this sensor were installed so that the sensor wires entered through the top of the back of the sensor (see Figure 42). The orientation of the sensor affects the position of the DP1/DP2 jumpers. Depending on how the sensor is installed, be sure to confirm that the jumpers are in the proper position for the 0-1 V setting as shown in the figures below. This applies to all indoor temperature/humidity sensors connected to the LC controller. See illustration mounted inside of sensor cover for further detail on jumper position.

Always start sensor troubleshooting by verifying connections at the sensor board and at the LC6000 terminal blocks. Improper connection will cause inaccurate readings. Next, verify continuity at both ends of wires running between the sensor and the LC6000. A severed or damaged wire will cause inaccurate readings. As a last step, verify voltage and resistance at the sensor and the LC6000 terminal block per the provided table. If the sensor is found to be malfunctioning, replace the sensor.
