If only one wall-mounted air conditioner is being used, it can be matched with either the LC6000 supervisory controller or a th-Tune stand-alone controller. 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 telecom/motor control center rooms. NOTE: The LC6000 supervisory controller and MULTI-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 wall-mount units. They are a complete system, and must be used together. Controller LC6000 controller and accessories included shown below. LC6000 Series TEC-EYETM Hand-Held Diagnostic Tool Bard P/N 8301-059 LC6000 Series Programmable Logic Controller Remote Temperature/ Humidity Sensor* (with 35' shielded cable) Bard P/N 8403-079 Communication EMI Filters Bard P/N 8301-055 * One remote temperature/humidity sensor and 35' of 5-wire shielded cable are included with the LC6000 controller. If the site in which the LC6000 controller will be used has more than one zone (maximum three zones per LC6000), additional remote temperature/humidity sensors (one sensor per zone) will need to be purchased and installed in the additional zones. One additional temperature-only sensor (Bard P/N 8301058) may also be used in Zone 1 but will also need to be purchased separately. Temperature-only sensors require field-supplied 2-wire shielded cable. The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.

FIGURE 10 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 freecooling 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 freecooling 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 freecooling 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 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. Dehumidification The supervisory controller will monitor the indoor relative humidity of each zone and compare the value to three setpoints for each zone. The three setpoints will be described as dehumidification off, passive dehumidification and active dehumidification. The default value for these setpoints will be 60%RH, 70%RH and 80%RH, respectively. When the humidity level inside the shelter falls to the dehumidification off setpoint, the system will stop attempting to dehumidify the space. When the humidity level rises to the passive dehumidification setpoint, all units with economizers will disable the use of economizers for cooling calls. This will act as passive dehumidification by forcing the use of compressor for space cooling. Availability for passive dehumidification will be determined by model number. All units with economizers will be considered. When the humidity level rises to the active dehumidification setpoint, the controller will activate staged dehumidification. The controller will then calculate a dehumidification demand based on how far above the setpoint and how long the RH level has been above the setpoint. The demand 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 the zone up to an optional maximum number of units running value. Availability for active dehumidification will be determined by model number. Units with concurrent electric reheat or mechanical dehumidification will be considered. NOTE: Only one type of dehumidification unit will be considered depending upon configuration of the supervisory controller. Unit capability is determined by the model number.
