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.
