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. Location height should be approximately 60"...
Up to two additional temperature and humidity sensors can be purchased and installed. Alternately, temperature- only sensors can be purchased and installed instead of the combination sensors. Use shielded cable to connect additional sensors to controller. FIGURE 23 Additional Remote Temperature and Temperature/Humidity Sensor Installation Up to two additional temperature/humidity sensors may be added.
Additional LV1000 Connections There are factory-installed jumpers across terminals #10 and #11 (hydrogen detector), #12 and #13 (generator run) and #14 and #15 (anti-theft device). Remove the factory-installed jumpers before connecting to the hydrogen detector, generator and/or anti-theft device (if applicable). INPUTS LV1000 Connections Sensor Connections...
Communication Wiring Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figures 24, 25 or 26. The daisy chain does not need to follow the addressing order. The communication wire should be 2-wire, 18 gauge shielded cable with drain.

LV1000 Supply Wiring The LV1000 controller is powered by -48VDC from the shelter. A field-supplied 5 amp DC circuit breaker is required. Field-supplied supply wiring should be minimum 16 gauge, maximum 14 gauge (see Figure 30). 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;...
