E-Flex Room Controller Installation and Manual, Rev. 1.02 2
Glossary of Terms
Demand Response -
Energy codes and energy companies have growing requirements to reduce your power consumption
during high-energy usage. The Room Controller meets these energy requirements by accepting a contact
input from the power company to impose a maximum output per zone.
LightsOut -
LightsOut is the period of time when lights should be at the LightsOut preset (typically, Off) unless there
is user intervention. Before activation of the LightsOut preset, lights will flash three times to warn
occupants of the upcoming change. After a delay the LightsOut preset will be activated. During this
delay, any button press at any station will further delay the activation of the LightsOut preset. Once the
LightsOut preset is in effect, light levels may be changed by a user. After 15 minutes of no inactivity, the
LightsOut sequence will start again.
Occupancy Mode –
Automatically turn lights ON when the occupancy sensor input detects the presence of a person and will
automatically turn lights OFF when no presence is detected for a specified amount of time.
Vacancy Mode –
Lights must be turned on manually by someone entering a room or area. The system will then
automatically turn lights OFF when no presence is detected on the occupancy sensor input for a
specified amount of time.

E-Flex Room Controller Installation and Manual, Rev. 1.02 7
Low Voltage Wiring
Follow all national and local codes for separation requirements. Do not combine Class 2 and Class 1
wiring. Low voltage control cables must be run in separate conduit from input power wires. Do not
connect 24V supplies between two or more controllers sharing same input signals. However you must
connect the COM signal.
CapT2 Station Connections
Note:
24V power for CapT stations over Cat5 can only be provided by one
source. By default, the EFRC does not provide power to the
stations. A jumper (JP2) on the room controller enables or disables
the 24V power to the EFRC RJ45 connectors. (See EFRC unit load
capability).
CapT2 stations and the E-Flex room controller all have two RJ45 connectors to connect devices together
in a system using standard Cat5 cable. Maximum cable runs 300 ft.
CapT Power Enable/Disable
Jumper JP2 is used to enable or disable power to the CapT station RJ45
connectors. The jumper in position 1-2 (default) disables power to the
connectors. The jumper in position 2-3 (shown) enables power to the
connectors.

CapT2 Station Configuration
There are four CapT signals available on the Cat5 cable connecting stations and E-Flex controllers
corresponding to a physical input on the controllers. Each CapT signal can have multiple stations
connected to it (see power load capability). Each CapT signal is then assigned to control a zone(s) on the
E-Flex room controller using either hardware jumpers or software configuration (E-Flex Flextool for
Windows).
Assigning CapT Stations to CapT Signal
The stations are assigned to one of the CapT signals using a four position rotary switch (SW2) on the rear
of the station. More than one station can be set to the same rotary position connecting multiple stations
to the same CapT signal so they control the same zone(s).
Position 0 –CAP1
Position 1 –CAP2
Position 2 –CAP3
Position 3 –CAP4 (E-Flex relay panels only)
Assigning Zones to CapT Signal with Jumpers (on EFRC)
The stations are first assigned to one of the CapT signals (See above). CapT signals are then assigned to
control a zone or zones on the room controller. Zone assignment can be done without software using
hardware jumpers JP1 and JP3.

Power Up and Configuration
Pre-Check
Clean out metal scraps, dust, and debris from the room controller enclosure.
Inspect low and high voltage wiring for loose connections, bare or damaged insulation.
Mount the high voltage cover.
Verify that all configuration dip switches and jumpers are set per the installation requirements.
See section on switch configuration, page 11.
Power Up
Apply power with breaker supplying power to the room controller.
Test each contact input and ensure the configured relays respond as expected and the relay
status LEDs track the response.
If DMX is being used to control the room controller, verify operation using the DMX controller
for the system. If no DMX signal is present then relay LED 1 will blink otherwise it follows the
state of the relay.
Emergency Test
The UL924 model of the E-Flex room controller includes an integral automatic control relay. This relay
tracks relay 1 and is capable of up to 3A (electronic ballast) @120 or 277 VAC. On power loss this relay
closes to feed the emergency HOT to the emergency load. In addition, the 0-10V COM signal is also
opened so that any 0-10V ballasts go to full brightness.
All emergency lighting systems should be tested monthly. This is a short functional test in accordance
with BS EN 50172:2004 / BS 5266-8:2004. To perform this test on the E-Flex room controller press the
test button located on the low voltage entry side of the controller. This will de-energize the relays,
closing the UL924 automatic control relay, and disconnecting the 0-10V dimming common.
Reset Factory Defaults
Hold SW2 down for 3 seconds until all relay LEDs begin to blink, then release. On release the
configuration will be reset to factory defaults. If the dip switch settings for sensor zone assignment were
overridden by a software configuration this step will return control back to dip switch settings, i.e.
hardware configuration.
