1 LC6000 Controller used with MULTI-TEC Wall Mount Units Specification Sheet & Application Guide FEATURES OF THE LC6000 CONTROLLER Control up to 14 units with a single LC6000 controller. Complete control of all units is conveniently located in one controller, and unit operation is controlled through the single interface. The LC6000 allows remote access via Ethernet connection to all functions of the controller system. Setpoint adjustment and unit monitoring of several LC6000 equipped buildings and shelters can take place from one remote central location. Modbus may be used to communicate with the LC6000 controller. Remote mounted temperature and humidity sensor. The LC6000 can be mounted in an area convenient for the user, and the temperature and humidity sensor can be located remotely for the best temperature reading in shelter or building. Up to three separate temperature and humidity controlled zones. By using zoned cooling and heating, multiple building or shelter areas can have independent temperature setpoints with the use of a single LC6000 controller. Automated run test process to verify unit functionality. Once the units and controller are installed, a pre-programmed automated run procedure verifies blower, damper, compressor and electric heat operation. Comfort mode setting of 72 F. When technicians and service personnel need to enter the building or structure, the LC6000 can be set to a comfortable work environmental temperature for 60-minute intervals. The controller includes a large 132 x 64 pixel graphic backlit display and six button keypad for easy programming and setup. With the easy-to-read display and intuitive menu system, programming the controller is done with minimal effort. Post-painted heavy gauge steel controller enclosure with 1.500" and.750" electrical knockouts an all sides. A double-hinged cover allows access to components inside, and a quarter turn latching fastener secures the front door when closed. Overall size of the enclosure is a 6.06" depth x 12.00" width x 16.13" height. The temperature display can be set to Fahrenheit or Celsius. Alarm functionality. User-defined critical or non-critical alarms include: replace filter, free cooling damper failure, air temperature sensor failure, zone remote temperature and humidity failure, smoke/fire, high/low temperature, pressure and hydrogen. TEC-EYE TM diagnostic tool. The TEC-EYE TM diagnostic tool allows troubleshooting and control of the unit without the need of the LC6000 controller. By using the hand-held device, the service technician or installer is able to make programming changes and verify unit functionality at the outdoor mounted Bard wall mount unit without the need to access the LC6000 inside the building. Two (2) EMI line filters. The use of EMI line filters at each end of connecting cables prevents interference caused by electronics inside the shelter or building. Optional smoke/fire alarm. The LC6000 allows the use of a remote mounted smoke/fire alarm or whole building alarm system (not included). Optional 3 Stage electric heat control. When paired with the WA Series units, 6kW, 9kW, and 15kW staged electric heat is programmed into the controller, and can be field adjusted if needed. Staged cooling with optional free cooling mode economizer. The LC6000 can control building cooling functionality including unit rotation or intuitive load balancing. The unit will determine which mode of cooling needs to be employed based on outdoor temperature and humidity level. If free cooling is not the most efficient solution, compressor cooling mode (2nd stage) will be used. Cooling setpoint is fully adjustable between 65 F and 90 F. The default setpoint is 77 F.

2 CAPABILITY AND CONNECTION Zone Control Capability: The LC6000 is capable of controlling up to three (3) separate zones of operation with various options in each zone. Zone 1 is the primary zone of operation, because it contains a temperature and humidity sensor, and can contain an optional remote temperature sensor for temperature averaging. Zones 2 and 3 will have separate temperature and humidity sensors for area separation and zoned climate control. Each zone has normally open contacts for humidifier operation. Multiple smoke alarms may be used, wired in series in any of the zones. Connection on Features: Control 1 to 14 MULTI-TEC units each with their own PLC logic boards. Each unit is addressed and can be individually controlled. Temperature and humidity sensing can be accomplished in 1 to 3 zones. Humidifier Normally Closed contacts for connection in 1 to 3 zones. Fire/smoke alarm Normally Closed contacts for connection of 1 or multiple alarms in series. MULTI-TEC units are daisy chain connected through the use of 2-wire with drain (ground). Zone 1 can be set to different temperature and humidity settings with optional remote temp. for temp. averaging LC5000 LC6000 Controller Zone 3 can be set to different temperature and humidity settings.

3 LARGE STRUCTURES WITH MULTIPLE COOLING & HEATING ZONES The capability of zoned control makes the LC6000 and MULTI-TEC units ideal for large structures with various equipment heat loads. The below diagram illustrates a typical large equipment shelter layout with three (3) zones of cooling. MULTI-TEC units are placed around the outside walls of the structure to cool the equipment inside. Each zone and the corresponding units are programmed into the LC controller to allow for individual temperature control. The LC controller will use the ceiling or wall mounted temperature and humidity sensors along with the return air temperature sensors in the MULTI-TEC units to control the temperature in each zone. The units operate based off of the average temperatures of all sensors in the zone the units are assigned to or based upon MULTI-TEC units with the greatest differential between setpoint or return air temperature sensors.

4 UNIT PLACEMENT IN ZONES The LC6000 controller is capable of controlling between 1 and 14 MULTI-TEC units. Each MULTI-TEC unit and the LC6000 controller contain a PLC logic board. All units and the LC6000 controller are daisy chain connected together using 18 ga. 2-wire with drain. Through the daisy chain, all units communicate with the LC controller. Each unit is addressed separately, and the LC controller is able to control each unit individually. When used with up to 3 zones, the installer can choose how many units to have in each zone, with up to 14 total units in all zones. This will allow a choice of installing as many units as needed in each zone based on cooling capacity needs, and controlling each of the units with the LC6000 controller. A single zone system may contain up to 14 units. All units will be controlled by one temperature and humidity sensor. Zone with 14 units LC5000 LC6000 Controller A zone could possibly contain only 1 unit. The one unit will be controlled by a temperature and humidity sensor.

5 Temperature/Humidity TEMPERATURE & HUMIDITY MEASUREMENT IN 1-3 ZONES The installer has the ability to have up to three (3) zones of temperature and humidity control. Each zone has a temperature and humidity sensor that connects directly to the LC controller using 18 ga. 5 wire. Zone 1 has the ability to connect an additional temperature sensor for temperature averaging or highest temperature unit operation that connects to the LC controller using 18 ga. 2 wire. With the use of separate temperature/humidity or temperature only sensors in each zone, the installer can monitor and control three (3) areas independently. Zone 1 can be set to different temperature and humidity settings with optional remote temp. sensor for temp. averaging or highest sensor temperature for unit operation.

6 USE OF HUMIDITY SENSOR Each temperature/humidity sensor has the ability to monitor the humidity level in each zone. Through the use of a field supplied humidifier connected to the provided normally closed contact points inside the LC controller, the humidity level in each zone may be increased to an adjustable %RH setpoint. Each MULTI-TEC unit also has the ability to disable outdoor ventilation air entering the building when humidity levels inside the structure reach an adjustable %RH setpoint to avoid condensation.

Alarming/Accessory Connection Points: All external wired alarms, sensors and accessory items connect to the terminal block located in the lower area of the LC controller. MODES OF OPERATION, ZONE PLANNING & SENSOR LOCATION The LC6000 Controller is highly advanced and allows for improved temperature and humidity conditions inside a structure, but system setup is very important in order to maximize the benefits it offers. The following considerations need to be made when setting up a system using the LC6000 and multiple MULTI-TEC units. 1. Structure Zoning: The LC controller has the ability to operate up to three (3) separate zones of temperature control. It is important to consider the heat load inside the structure and the cooling capacity needed for each area of the building to maintain the desired temperature. Multiple units may need to be assigned to each zone for cooling capacity, unit redundancy (N+1), standby or equal run time. Careful examination of the structure floor plan and equipment inside should be completed to ensure all application requirements are met. Large structures with multiple rooms or large areas should consider multiple zones of operation. Small structures with very few units should consider 1 single zone of unit operation. 2. MULTI-TEC Unit Location: It is very important to install the MULTI-TEC wall mount units in areas where they will be able to keep the structure temperature within the shelter design parameters with various heat loads inside. Thought should be given regarding equipment racks, variable drives, turbines, motors, batteries and other heat sources in the structure and how the air will be circulated inside the structure. Avoid indoor areas where supply and return openings will be blocked by equipment placed inside the structure and follow all outdoor clearances provided in the Installation Manual and Specification Sheets. 3. Smoke and Hydrogen s for Alarming: Smoke and hydrogen sensors need to be located per building codes. Multiple smoke detectors may be connected to the LC controller in series if this will meet code requirements. The MULTI-TEC unit also has connection points if a smoke detector is required by code to connect directly to the unit. Alarming of the smoke detector when connected to the LC controller will disable all MULTI-TEC units connected to the controller. Alarming of the smoke detector when connected to the MULTI-TEC unit will disable only the specific unit connected to the smoke detector. Alarming of the hydrogen detector will open the economizer damper and ventilate the structure. 4. Temperature/Humidity and Temperature Only s: Multiple sensors can be connected to the LC controller to measure humidity and/or temperature. Zone 1 (or single zone operation) may have one temperature and humidity sensor and an additional remote temperature only sensor. Zone 2 (optional) may have one temperature and humidity sensor. Zone 3 (optional) may have one temperature and humidity sensor. 5. LC Controller Location: The LC controller does not include internal temperature or humidity sensors, and may be placed in any location easily accessible inside the structure. The LC controller is not rated for outdoor use and must be kept in an environment not exposed to rain or outdoor weather conditions. 6. LC Controller Cooling Mode of Operation: Two (2) separate cooling modes of operation are available to control the MULTI-TEC units using the LC controller: Unit Rotation Mode is used when equal wear time is desired among all MULTI-TEC units installed on the structure. By rotating First On and Next On operation among units being used to cool the structure, the LC controller is able to maintain temperature setpoints and equalize run time among the units being used. The First On unit will begin to cool the structure, and additional Next On units will be called into operation as necessary to maintain programmable temperature setpoints in the LC controller. As temperature conditions reach the temperature setpoints in the LC controller, the number of units being used will decrease using a First In, First Out (FIFO) strategy. The FIFO strategy will decrease the number of units being used by removing units from operation that were first called on to cool the structure. The First On unit will be the first unit to cease cooling the structure, followed by the Next On units. Page 9 of 23

10 UNIT ROTATION MODE Unit rotation mode allows for separate cooling and heating zones to use multiple units in unit rotation operation. Each zone may use different temperature setpoints, and have their own unit rotation. All zones use the single LC controller. Each MULTI-TEC unit in a specific zone is dedicated to either heat or cool depending upon the signal sent by the LC controller. Unit #1 Unit #9 Zone 3 Unit #2 Unit #8 Zone 3 has (2) units. On a preprogrammed schedule, unit #8 and #9 will take turns as First On and Next On unit. Zone 2 Zone 2 has (3) units. On a preprogrammed schedule, unit #1, unit #2, and #3 will take turns as First On, Next On 1 and Next On 2 unit. Unit #3 Unit #7 Unit #4 Zone 1 Unit #6 Zone 1 has (4) units. On a preprogrammed schedule, unit #4, unit #5, unit #6 and #7 will take turns as First On, Next On 1, Next On 2 and Next On 3 unit. Unit #5 Page 10 of 23

11 SMALL STRUCTURES WITH SINGLE ZONES, UNIT ROTATION MODE The capability of zoned control makes the LC6000 and MULTI-TEC units ideal for large structures with various equipment heat loads. The below diagram illustrates a typical large equipment shelter layout with three (3) zones of cooling. MULTI-TEC units are placed around the outside walls of the structure to cool the equipment inside. Each zone and the corresponding units have been programmed into the LC controller to allow for individual temperature control. The LC controller will use the ceiling or wall mounted temperature and humidity sensors along with the return air temperature sensors in the MULTI-TEC units to control the temperature in each zone. The units operate based off of the average temperatures of all sensors in the zone the units are assigned to. Unit #4 Unit #1 Zone 1 Unit #3 Zone 1 has (4) units. On a preprogrammed schedule, unit #1, unit #2, unit #3, and #4 will take turns as First On, Next On 1, Next On 2 and Next On 3 unit. Unit #2 Zone 1 Zone 1 has (2) units. On a preprogrammed schedule, unit #1 and unit #2 will take turns as First On and Next On unit. Unit #1 Unit #2 Page 11 of 23

12 MODES OF OPERATION, ZONE PLANNING & SENSOR LOCATION (CONTINUED) Intuitive Load Balancing is used to improve temperature control throughout the zone and reduce high air temperature areas (hot pockets of air). When temperatures increase to a point where cooling is needed, the First On unit is decided by operating the unit that is seeing the highest return air temperature in the zone. Additional Next On units will be decided based on next return air temperature measured by additional units in the cooling zone. PATENT PENDING Consideration of which mode of operation will be used should be made when setting up the structure. Mode of operations can be changed at any time through the setup procedures in the LC controller, but when using multiple zones, all zones must use either Unit Rotation or Highest Temperature mode. 7. MULTI-TEC Unit Mode of Operation: Two (2) separate modes of operation are available for the MULTI-TEC units: Active Mode: MULTI-TEC units in this mode are in rotation and will sequence routinely during a call for heat or cooling, the order is based on a lead/next on rotation schedule. Standby Mode: MULTI-TEC units in this mode are not in rotation and will only operate during a High Temperature Alarm Level 1 (cooling mode), or a Low Temperature Alarm (heating mode). STAND ALONE OR ORPHAN MODE OF OPERATION When communications are lost between the LC controller and the MULTI-TEC units, the MULTI-TEC units are capable of running in stand alone or orphan mode. The unit will utilize the return air sensor as a thermostat and follow the same logic used when the control was initiating the unit. When the setpoint is reached at the return air sensor, the unit will engage, verify if free cooling is available, then bringing on the correct mode of operation to satisfy setpoint. The unit controller stores the last setpoint that it saw before losing communication and that is what it attempts to maintain. When a unit is first installed there are factory default setpoints in the unit, so if it is powered up before the shelter controller is installed, it will run to maintain the default setpoint. Once a controller is connected to the unit, the controller will push down the current setpoint to the unit controller. For the unit controller to return to the default setpoint, a restore factory defaults command could be executed from the TEC-EYE TM. Page 12 of 23

14 LC CONTROLLER COOLING FUNCTIONALITY 1. The LC controller monitors each zone by measuring the temperature at the remote wall or ceiling mounted temperature sensor(s) and each of the unit return air sensors. These sensors provide feedback to the LC controller, which activates cooling operation based on average or highest (user selectable) temperature in each zone. 2. The LC controller signals active MULTI-TEC units to operate either in rotational mode or temperature priority mode based on the selected setpoint. Once activated, the MULTI-TEC unit decides the best for procedure for cooling based on outdoor temperature and humidity. If conditions are acceptable, the unit will economize if an economizer is present in the unit. If the conditions are not acceptable for economizing or an economizer is not present, the unit will operate in mechanical cooling. 3. Units will operate first on, next on, next on, and so on, providing cooling. The LC controller will select which units operate based on the mode of operation (rotation or temperature priority). 4. After the temperature falls below the setpoint (into the dead band area), as long as the temperature is in the band, no further units will be called on (additional units remain idle) and when the temperature reaches the low setpoint a unit will be sequenced off every 60 seconds until all are off (see diagram below). If the temperature begins to rise (existing units not keeping up with the load) the remaining unit(s) in the zone will start to cycle on again every 120 seconds. Cycle times, sequencing and dead band are adjustable settings through the use of the LC software. If any zone reaches the Temperature High Limit Level 1 temperature setpoint, all units in the zone will go into compressor cooling mode that are using economizer operation. If any zone reaches a Temperature High Limit Level 2 temperature, an alarm will activate on the LC controller. LC Cooling Unit Staging Unit Staging Off Band On Page 14 of 23

15 LC CONTROLLER HEATING FUNCTIONALITY 1. The LC controller monitors each zone by measuring the temperature at the remote wall or ceiling mounted temperature sensor(s) and each of the unit return air sensors. These sensors provide feedback to the LC controller, which activates heating operation based on average or lowest (user selectable) temperature in each zone. 2. The LC controller signals active MULTI-TEC units to operate either in rotational mode or temperature priority mode based on the selected setpoint. Once activated, the MULTI-TEC unit activates electric heat strips to warm the shelter. 3. Units will operate first on, next on, next on, and so on, providing heating. The LC controller will select which units operate based on the mode of operation (rotation or temperature priority). 4. After the temperature rises above the setpoint (into the dead band area), as long as the temperature is in the band, no further units will be called on (additional units remain idle) and when the temperature reaches the high setpoint a unit will be sequenced off every 60 seconds until all are off (see diagram below). If the temperature begins to drop (existing units not keeping up with the heating requirements) the remaining unit(s) in the zone will start to cycle on again every 120 seconds. Cycle times, sequencing and dead band are adjustable settings through the use of the LC software. If any zone reaches Low Limit temperature, an alarm will activate on the LC controller. LC Heating Unit Staging Unit Staging On Band Off HUMIDIFIER OPERATION The LC controller provides one set of normally open contacts for each of the three zones of operation to energize a humidifier in each zone of operation. The user can adjust settings through the LC controller to operate the humidifier contacts. HIGH HUMIDITY OPERATION The LC controller will alarm on high humidity levels in each zone of operation and close the economizers (if installed) in the MULTI-TEC units. COMFORT MODE OPERATION The LC controller has a comfort mode of operation to allow service technicians to enter the structure and perform service work at a comfortable temperature for a certain period of time. Once the time limit is reached, the MULTI-TEC units will operate at normal set points unless comfort mode is reactivated. Temperature and mode duration are adjustable setpoints. Page 15 of 23
