DESCRIPTION
Hubbell Building Automation’s NX Room Controller is a self-contained intelligent power
pack. It contains either one or two independently controlled outputs. Optional 0-10VDC
outputs are available for controlling dimmable ballasts and LED drivers. The NX Room
Controller also features four Smart Ports that provide plug and play support for NX
occupancy sensors, daylight sensors and manual control switches. The NX Room Controller
can operate stand alone or networked with other NX controls.

INSTALLATION
1. DO NOT DISCARD THE INCLUDED MAC ADDRESS LABELS. SEE STEP (5) BELOW.
2. Turn power off at the service panel.
3. Mount the Room Controller (RC) to the outside of a junction box using the Room
Controller’s extended ½” chase nipple. Secure to box with enclosed EMT nut. (See
Figure 1)
4. The Room Controller has a MAC address label affixed to the outside of the unit. Place
the enclosed MAC address label(s) in a log book and record the location of the Room
Controller and the circuit(s) it controls. The MAC address will be needed later during
the system setup process.
5. If control devices (e.g. occupancy sensors, daylight sensor and switches) are going to
be used, attach them to any available Smart Port with the appropriate CAT5 device
cable. Similar devices (e.g. switches) may be daisy chained together from the same
Smart Port. ( See Figure 2)
6. Electrically connect the Room Controller to the circuit(s) as shown in Figure 3. Reapply
power at service panel.
7. Test installation as follows:
a. Momentarily press Button A to toggle Load A (red wire) ON and OFF
b. Momentarily press Button B to toggle Load B (blue wire) ON and OFF (2 Relay
Models Only)
c. With Load A ON, press and hold Button A down to dim Load A down.
Release Button A and press again to dim Load A up.
d. With Load B ON, press and hold Button B down to dim Load B down.
Release Button B and press again to dim Load B up.
OPERATION GUIDE
The NX Room Controller is designed to control and manage lighting within a single room
or zone in a building. Working in conjunction with an occupancy sensor(s), daylight sensor,
and wall switch station(s), the room controller intelligently responds to inputs to perform
the required lighting control sequence of operation. The room controller operates with the
connected control devices as a stand-alone local control system but can be extended to
participate in a building-wide networked lighting control system with the addition of the
NXHNB Network Bridge Module.

CONNECTING MULTIPLE ROOM CONTROLLERS
Room controllers can be inter-connected to expand the number of relays and dimmers in
the room or to allow the use of more than one voltage. Use CAT5 cable(s) to connect the
room controllers in a daisy chain configuration. That is, no more than one RJ45 port in each
room controller should be used for this connection. A maximum of 8 room controllers may
be connected for a maximum of 16 relays and 16 dimmers. Self configuration will function
normally up to a maximum of 6 loads. Manual configuration will be required beyond 6
loads.
CONNECTING LOW VOLTAGE CONTROL DEVICES
The Room Controller provides a source of 24 VDC current to power the connected control
devices such as switch stations and sensors. A maximum of 250 mA of 24 VDC current is
available. Since the control components draw differing amounts of current, the following
table should be used to determine how many control devices can be connected to a single
room controller. In cases where two or more room controllers are connected together, the
power budget is determined for each room controller based on the control devices that are
plugged into that room controller. See Figure 3.
MAXIMUM POWER BUDGET PER ROOM CONTROLLER = 30 LOADS
Switch station = 1 Load
PIR only Occupancy sensor = 1 Load
PIR only Occupancy sensor with RP option = 2 Loads
Dual Technology and Ultrasonic Occupancy sensor = 3 Loads
Dual Technology and Ultrasonic Occupancy sensor with RP option = 4 Loads
Daylight Sensor (photocell) = 1 Load
NOTE: Only one daylight sensor can be connected in each room/zone
SELF CONFIGURATION
The sequence of operation in the room will automatically reconfigure as devices are
plugged into the room controller as described in the following sections. Note that self
configuration will automatically be disabled once the room has been maunally configured.
See Manual Configuration section.
OCCUPANCY SENSORS
The NX room controller is compatible with any low voltage Hubbell Building Automation
vacancy/occupancy sensor that uses the red/black/blue control wires. A wiring adapter
(
RJ45ADAPTOR
) is required to make the wiring transition from the flying leads on the
sensor to the RJ-45 Smart Port on the room controller. Hubbell Building Automation
sensors ordered under model
NXOS
series model numbers are automatically supplied with
the adapter and a short CAT5 jumper cable.
The sensor can be connected to the Room Controller Smart Port using a pre-terminated
CAT5 cable (see Figure 3). Alternately, the adapter can be connected to the Room
Controller Smart Port and one or more sensors connected using traditional low voltage
wiring. The adapter is color coded to match the flying leads on the sensors.
NOTE: Once any NX digital switch station is connected to the Room Controller, the mode
of operation will automatically switch to vacancy mode (manual on) for all loads. To
change one or more load(s) to automatic on operation see Manual Configuration section.
DIGITAL SWITCH STATIONS
The NX Digital Switch Stations will automatically configure themselves to control the
available loads within 5 seconds after being connected to the Room Controller. For best
results, do not press any buttons for 5 seconds after plugging in a switch station. This allows
time for the system to self configure and stabilize.
Model number switch stations
NXSW-1, NXSW-2, NXSW-3, NXSW-4, NXSW-6
will have
all buttons configured for ON/OFF toggle operation by default. These stations will self
configure to sequentially control the loads. For example, a
NXSW-1
will control load 1, a
NXSW-2
will control loads 1 and 2, etc. The relationship between the buttons and the loads
can be changed. See Manual Configuration section.
NOTE: If the zone has more loads
than buttons, the last button in the sequence will automatically control the remaining
loads. This insures that no load is left uncontrolled during the self configuration process.
The NX Specialty Switch Stations model
NXSW-OO
and
NXSW-TO
will self configure the
same as the
NXSW-1
as described above.
The NX Specialty Switch Stations model number
NXSW-RL
,
NXSW-SS
and
NXSW-ORLO
have dimming functionality and will self configure to control all loads. The relationship of
the stations to the dimmed loads can be changed. See Manual Configuration section.
