Unison Echo® Room ControllerETC

Echo Distributed Power Series

GENERAL INFORMATION

The Echo Room Controller offers a full power and control solution for
standalone and integrated room controls. With up to eight zones of
relay switching with 0-10V control fully rated at 20 amps, the Echo
Room Controller is the perfect solution for a single mid-sized room
with stand-alone TimeClock and sensor control. The controller can
also be used for full room integration utilizing an integral station
power supply, contact input, Demand Response input and UL924
emergency bypass. The controller can be wall-mounted or in an air
plenum to be easily tucked out of sight.

SPECIFICATIONS

FUNCTIONAL

• Control for up to eight zones of relay control for lighting and plug loads

• Control for up to eight zones of fully isolated 0-10V dimming control for LED drivers and fluorescent ballasts

• Each pair of power and 0-10V outputs can be patched to a space and zone via the EchoAccess mobile app

• Contact Input responds to closure to place the lighting into a configurable, presentation-friendly preset, playback a lighting control
sequence, trigger room combine, or any other Echo contact input function

• UL924 emergency-lighting control via contact closure or integrated normal sense feed

• Demand Response input sent from a power company can enforce a maximum level per circuit while active

- Demand Response commands can be transmitted to additional Echo devices via the EchoConnect bus

• Time-of-day, astronomical and calendar events for the installed room, and up to 15 additional rooms (TimeClock versions only)

• Plug and Play: ready to go out of the box, no software or external programming required

• Supports up to 6 Echo control products and 5 additional Echo output products with internal Echo Station Power Supply

• Supports up to 16 Echo control products and 15 additional Echo output products with external Echo Station Power Supply

MECHANICAL

• Constructed of 16-gauge cold-rolled steel, finished in fine-textured, black powder coat

• Supports wall-mount and plenum installation

• Rotary dials for selection of space and starting zone number

• Class one voltage barrier prevents access to line-voltage wiring with front panel removed
