Product Usage Instructions

• Before using the LMRC-111/112 room controller, read and follow all safety instructions. Do not use the product outdoors or mount it near gas or electric heaters. Mount the equipment in locations and at heights where it will not readily be subjected to tampering by unauthorized personnel. Do not use accessory equipment not recommended by the manufacturer, and do not use this equipment for other than intended use. Installation should be performed by qualified service personnel.
• To mount the LMRC-111/112 room controller, it can be placed in the plenum space external to any junction box with 1/2 knockouts. All line voltage wiring is #16 AWG, and each relay is rated for up to 10A. The total load for LMRC-112 should not exceed 10A, and specified load types can connect to any load relay. Do not connect different load types to the same relay.
• For dimming ballasts, either or both the Class 1 and Class 2 0-10V wires may be connected. For Class 1 Dimming, wiring is 18# AWG. Connect the 0-10V control wires to the 0-10V terminals that match the load relay output connection. Class 1 is preferred in new installations when the purple and pink dimming signal wires are included in the fixture power cable. Class 2 is used for new or existing installation when it is easier to run the purple and pink dimming signal wires outside the fixture cable.
• Class 1 and Class 2 wiring should be maintained throughout the installation and cannot be swapped – appropriate wiring practices should be used. Class 1 and Class 2 circuitry in the LMRC units are galvanically isolated. The LMRC-111/112 communicates to all other DLM devices connected to the DLM Local Network. The low voltage LMRJ cables can connect to any DLM device with an open RJ45 receptacle.
• It is important to note that to connect a computer to the DLM Local Network, use the LMCI-100. Never connect the DLM Local Network to an Ethernet.

PLUG N’ GO OPERATION (PNG)

Plug n’ Go supports the most energy efficient control strategy. For example, if at least two loads, one switch and one occupancy sensor are connected to the DLM local network, the system operates load A as Automatic ON, Automatic OFF and load B as Manual-On, Automatic-Off. See DLM device Quick Start Guides to determine how each device affects the PNG operation of the LMRC-111/112.

Load Control Arbitration
To take full advantage of automatic PnG configuration, review these simple rules about load control arbitration. After the room controllers are connected to the DLM Local Network and powered up they automatically negotiate to determine which controller becomes the Master and which load numbers are assigned to each relay on the DLM Local Network. The Master is the controller with the most load relays and the highest serial number.

Example: In a DLM local network with only LMRC-112 room controllers, the LMRC-112 with the highest serial number is the Master, carrying Load 1. The next highest serial number would have Load 2, and so forth.

PLACEMENT EXAMPLE

USING THE LMRC-111/112 WITH EMERGENCY LIGHTING

When used with an ELCU
Wattstopper recommends using an ELCU device. In this scenario, the LMRC-111/112’s 0-10VDC dimming circuit is connected to and alters the light level of both normally powered lighting loads and emergency powered lighting loads. The 0-10V signal is generated individually by each ballast or driver when they are powered.
NOTE: Class 1 or class 2 dimming may be used. (Class 2 dimming shown in diagram.)

• When Normal Power is available:
  When Normal Power is available and the normal load
  has been turned off by any DLM device (OS, photocell, or dimmer switch, or LMRC override button), the ELCU will turn off the Emergency Load as well.

• When Normal Power is unavailable:
  When normal power to the room controller fails for any reason, the 0-10VDC dimming circuit in the LMRC-111/112 will revert to an open circuit. Since no device is controlling the 0-10V circuit, any fixture that is fed by emergency power will go full on. Fixtures fed by normal power will of course be off since there is no power available for their operation.
  NOTE: If additional normal and emergency lighting loads are controlled by the LMRC-112, a separate ELCU device is needed.

• When no ELCU is used:
  In this scenario, emergency lighting cannot be turned on or off by a DLM device, only dimmed. The normal lighting load has full control. As in the example with the ELCU, if normal power fails, the emergency load will go full on. If any Emergency Circuits are fed or controlled from a panel, they must be located electrically where fed from a UPS, generator, or other guaranteed source of power during emergency and power outage situations.
  NOTE: Class 1 or class 2 dimming may be used. (Class 2 dimming shown in diagram.)
  NOTE: If you use only a single set of 0-10VDC wires, the emergency load will dim the same as the normal load (when not in an emergency power only mode).

UNIT ADJUSTMENT – PUSH N’ LEARN (PNL)

Load Selection Procedure
A configuration button (Config) allows access to Wattstopper’s patented Push n’ Learn™ technology to change binding relationships between sensors, switches and loads.

1. Step 1 Enter Push n’ Learn
   Press and hold the Config button (on any DLM device) for 3 seconds.
   The red LED on the LMRC-111/112 begins to blink. When you release the button, the red LEDs on other communicating devices connected to the DLM Local Network begin to blink. They continue to blink until you exit PnL mode.
   All loads in the room turn OFF immediately after entering PnL, then one load will turn ON. This is Load #1, which is bound to switch button #1 and occupancy sensors as part of the Plug n’ Go factory default setting. All switch buttons and sensors that are bound to this load have their blue LED solid ON.

2. Step 2 Load selection
   Press and release the Config button to step through the loads connected to the DLM Local Network. As each load turns ON note the devices (switch buttons and sensors) that are showing a bright solid blue LED. These devices are currently bound to the load that is ON. The blue LED on the room controller or plug load controller connected to the load is also lit.

   • To unbind a switch or dimmer button from a load, press the switch button while its blue LED is ON bright. The blue LED goes dim to indicate the button no longer controls the load that is currently ON.
   • To unbind an occupancy sensor, press the up ( ) or down ( ) adjustment button while its blue LED is ON. The blue LED turns OFF to indicate the sensor no longer controls the load that is currently ON.
     Pressing the switch button or sensor up ( ) or down ( ) again while the load is ON rebinds the load to the button or sensor and the blue LED illuminates brightly.

3. Step 3 Exit Push n’ Learn
   Press and hold the Config button until the red LED turns OFF, approximately 3 seconds.

TROUBLESHOOTING

LEDs on a switch or sensor don’t light| 1.   Check to see that the the device is connected to the DLM Local Network.

2.   Check for 24VDC input to the device: Plug in a different DLM device at the device location. If the device does not power up, 24VDC is not present.

•   Check the high voltage connections to the room controller and/or plug load controller(s).

•   If high voltage connections are good and high voltage is present, recheck DLM Local Network connections between the device and the room controller(s).

---|---
The wrong lights and plug loads are controlled| Configure the switch buttons and sensors to control the desired loads using the Push n’ Learn adjustment procedure.
LEDs turn ON and OFF but load doesn’t switch| 1.   Make sure the DLM local network is not in PnL.

2.   Check load connections to room controllers and/or plug load controllers.

Lamps do not dim, or lamps drop out at low dim levels| 1.   Make sure a 0-10V dimming ballast and rapid start sockets are installed per the ballast manufacturer’s recommendation. Shunted sockets are typically not acceptable.

2.   Check wiring per ballast manufacturer’s instructions.
