EUT – Product Manual

Room Control Unit

The Room Control Unit (RCU) is the ‘brain’ of Onity’s new Wireless
Energy Management System(EMS). It receives the temperature,
humidity, guest settings, fan mode, motion status, and door status from
the various system devices and determines how to operate the HVAC
system and lighting control.

The RCU has six relay drivers for outputs, a local door switch input,
three setup buttons, three LED indicators, a local temperature sensor
input, and a Real Time Clock (RTC) interface. The RCU receives
transmissions from all the wireless devices via its on board radio.

RCU Power Up

When power is first supplied to the RCU, the three LEDs each flash
once, the initial configuration check is started, and the 16 DIP Switch
settings are read. These DIP Switch settings are ONLY read during

the power up routine. Any changes made to these settings will not
take effect until the unit is shut down and powered back up.

If there is no response from the on board radio, the CFG LED (red) will
flash. The unit will try once per second to communicate with the on
board radio. As long as no communication is found, the red LED will
continue to flash.

BFR – Building, Floor,
Room. The unique ID of
the RCU. This ID is
configured in all the
devices that will transmit to
this RCU..

If there is a response from the on board radio, the state of the LED will
depend on whether or not the unit has been configured. If the unit has
been configured with a valid BFR, the red LED will turn ON. If the
unit has not yet been configured with a valid BFR, the red LED will
turn OFF.

RCU Buttons

As stated above the RCU has 3 setup buttons. These are explained
below.

Configuration Button (CFG)

The CFG button is used to configure the BFR (Building, Floor, Room)
of the unit. At this time, the BFR is a randomly generated number.

Press and hold the CFG button for 3 seconds, then release. Upon
release, the red LED will flash once. Random numbers are generated
to make the BFR and these are written to the radio. The radio then
transmits an inquire message. If the BFR is already in use by another
device in the area, an ‘in use’ message is received. In this case, a new
BFR is generated and an inquire transmitted. This is repeated until no
‘in use’ transmission is received. If no ‘in use’ is received, then the
BFR is free to use and the red LED will turn on solid.

OB/CB Button

When the OB/CB button is pressed, the radio will send the Open
Binding message once per second for one minute, or until the OB/CB
button is pressed again. While the unit is transmitting this message, the
green LED will flash once per second.

While the unit is in the open binding mode, wireless devices such as the
WDDC can be bound to this RCU.

When either one minute has passed or the button is again pressed, a
close binding message is sent and the RCU exits the open binding
mode.

Fast Clock Button

The fast clock button is for testing purposes only. Whe n pr essed, one
second is the equivalent of one minute real time. Because the devices
bound to the RCU do not have a fast clock mode, this feature is not
recommended for use in the field. It was added only to facilitate testing
of the unit in the lab.

Monitoring of Wireless Devices

When the RCU receives status messages from the wireless room
devices, the settings are logged in the RCU memory. Anytime the
RCU needs to check one of these statuses, it will check its memory to
see the latest status from any of the wireless devices.

For example, if the RCU receives a message indicating that motion has
been detected, it registers this in its memory. This status will not
