IMPORTANT This installation instructions manual is separated into two sections. The first section of the manual explains the installation and set up of MULTI-TEC wall-mount units with an LC6000 controller. The second section explains the installation and set up of WR Series wall-mount units with an LC6000 controller. Check wall-mount unit model number information (found on the model/serial tag) prior to beginning the installation to ensure the proper instructions are being followed.

2-wire shielded cable with drain. Single Unit Operation A th-TUNE stand-alone controller (Bard P/N 8403-088) can be used in place of the LC6000 controller when only one MULTI-TEC wall-mount air conditioner is being installed. If using a th-TUNE stand-alone controller instead of the LC6000 controller, the alarm logging and remote communication capabilities of the LC6000 controller will not be available.

LC6000 Controller The LC6000 controller is part of the Free Cooling Unit system by Bard. 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.
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.
For proper operation, the remote indoor temperature/humidity sensor must be configured properly with the controller. An additional remote indoor temperature-only sensor can be purchased and installed in Zone 1. Also, temperature and humidity sensors can also be purchased and installed in Zones 2 and 3 (one per zone). For information on remote indoor sensor configuration, see page 26.
Smoke, Hydrogen and Generator Alarms The LC6000-100 controller is shipped with smoke detector, hydrogen detector and generator run contacts. There are factory-installed jumpers across terminals #6 and #7 (smoke detector), #8 and #9 (hydrogen detector) and #10 and #11 (generator run). Remove the factory-installed jumpers before connecting to the detectors and/or generator. FIGURE 16 LC6000-100 Series Connection for Smoke Detector, Hydrogen Detector and Generator Run (If Applicable) Generator...
Communication Wiring Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figures 17, 18 or 19 (page 30). The daisy chain does not need to follow the addressing order. The communication wire should be 2-wire, 18 gauge shielded cable with drain.

The steps outlined on the following pages show how to connect the communication wiring using the daisy chain method shown in Figure 17. If using the alternate method (as shown in Figure 18), the connections to the controller and each wall-mount unit will be the same but the filters need to be placed in the positions shown in Figure 19.

Supply Wiring The LC6000 controller is powered by 120, 208 or 230 volts from the shelter. Field-supplied supply wiring should be minimum 16 gauge, maximum 14 gauge (see Figure 23). 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.
