Control Requirements
EchoConnect
Echo interface devices require an ESD ground connection and EchoConnect,
which supporting control signal between the device and the connected Echo
control system. This connection is provided on a three-position terminal,
labeled EchoConnect, and accepts 0.2-4 mm2(24-12 AWG) wires.
EchoConnect is a bidirectional protocol that uses one pair of wires (data+
and data-) for both data and power. ETC recommends using Belden 8471 (or
approved equal) Class 2 wire. The total combined length of an EchoConnect
wire run (using Belden 8471, or equal) may not exceed 500m (1,640ft).
Electrical Requirements
Echo interface devices require 24 VDC (Class 2) external power in addition to
EchoConnect requirements. This auxiliary power is provided to the input
connector by an external supply. The unit draws a maximum of 40 mA during
normal operation. This connection is provided on a two position terminal,
labeled 24 VDC, and accepts 0.2-4 mm2(24-12 AWG) wires (typically black
and red wire pair).
Note: NEC Class 2 product are to be wired in accordance with NEC
Article 725 and local jurisdiction requirements. All power and control
wiring should be installed and terminated by a qualified installer and
should follow standard wiring installation practices.

Input and Demand Response Interface Wire Terminations
The Contact Input and Demand Response Interfaces provide four sets of
terminals (“In” and “V out”) for connection to a momentary (Input Interface
only) or maintained contact input. Terminals accept 0.2 mm2-4 mm2(24-12
AWG) wire. Each input supports wet or dry contact closures and includes a
related on board LED to indicate contact status.
Note: Input terminals accept 3 - 24 VDC and support 610 m
(2,000ft) of 1mm2(18 AWG) wire (round trip wire to the device)
when using 24VDC.
Output Interface Wire Terminations
The Contact Output Interface provides four sets of terminals (normally open
“N.O.”, normally closed “N.C.”, and common “COM”) for connection of
output relays. Terminals accept 0.2 mm2-4 mm2(24-12 AWG) wire. Each
output includes a corresponding on board LED to indicate the normally open
status of the relay.

Set Configuration Mode
The configuration mode switch allows selection between Basic and Custom
configurations of the interface. Basic is the factory default setting.
Basic
Basic configuration mode applies the following default behaviors:
Input Interface:
Inputs control Presets 1-4 respectively, using momentary input mode where
the closure behaves similar to an Echo Inspire station.
•
close / open event (push) executes a preset toggle
•
holding the contact closed (hold) performs a space raise
•
closing the closure twice (in rapid succession) performs a preset toggle
with 1/2 second override timing
Note: Use EchoAccess to assign a different Preset for the contact.
Note: Particularly when considering machine driven applications,
ETC recommends a minimum of 500ms between any input changes
to ensure transitions are reliably applied.
Demand Response Interface:
Activates Demand Response, affecting up four consecutive Echo Spaces,
starting with the interface Space rotary switch setting.
Example: Example: Setting the Space switch to 3 results in control
of Spaces 3, 4, 5, and6. A value higher than 13 will result in control
of only Spaces 14, 15, and16.
Note: Each Echo space can only have one assigned demand response
input.
Functionality:
•
a closed contact means the designated space is in active Demand
Response state
•
an open contact means Demand Response is inactive
Output Interface:
Relay outputs are controlled by Zones 1-4 respectively (when the Zone dial is
set to its default setting of 1). Changing the Zone dial will alter the starting
Zone. Reference the related note on page 7 regarding zone ranges.
Contact and Demand Response Interfaces Page 5 of 8 ETC

ETC Installation Guide
Contact and Demand Response Interfaces
Note: Functionality varies depending on whether the normally open
or normally closed contact terminal is utilized. The default behaviors
listed below are assuming a normally open installation. The normally
closed contact provides inverted behavior, its status always the
opposite of the normally open contact.
•
When the intensity of an assigned zone is non-zero the corresponding
relay output will be closed.
•
When the intensity of an assigned zone is equal to zero the
corresponding relay will be open.
•
By default, all odd numbered presets, when activated, will close all
relay outputs and all even numbered presets, when activated, will open
all relay outputs. This is true until the preset is recorded with the new
values.
Custom
Custom configuration mode applies the following default behaviors until
changed using the EchoAccess App:
Input Interface
Inputs control Presets 1-4 respectively, using maintained input mode where:
•
closing the contact activates the preset
•
opening the contact deactivates the preset
Demand Response Interface
Inputs control in spaces determined by settings applied in the EchoAccess
App.
Note: Each Echo space can only have one assigned demand response
input.
Output Interface
Relay outputs are controlled by the status of Presets 1-4 respectively.
•
When the status of an assigned preset is active, the corresponding
relay output will be closed.
•
When the status of an assigned preset is inactive, the corresponding
relay will be open.
Aside from the default behaviors when the configuration mode switch set to
Custom, complete configuration of the Output Interface is supported by the
EchoAccess App. For detailed information about custom configuration
options available, reference the EchoAccess App integrated help system.

Set Space and Address / Zone Start
Interface devices participate in an Echo control system using the configured
Space and Address / Zone which are selectable using the rotary switches on
the front of the unit. By default, these switches are set to Space 1, Address /
Zone 1.
1. Set the Space for this device (1 through 16 available). All control inputs
from the connected stations, sensors, and other controls are shared by
all devices within the selected space. This setting applies regardless of
the selected configuration mode (Basic or Custom).
Note: For the Demand Response Interface, setting the Space address
determines the four consecutive spaces that will be controlled. A value
higher than 13 will result in control of only Spaces 14, 15, and 16.
2. Set the Address / Zone:
•
For a Contact Input Interface, set the Address (1 through 16
available) which identifies the device in the selected space. This
setting always applies.
Note: Do not duplicate a device address within the same space.
•
For a Contact Output Interface, set the Zone number (1 through
16 available) for the first output on the interface. The remaining
outputs will be assigned consecutive zone numbers. The zone
number does not apply while in Custom configuration mode.
Note: When setting the first zone number, be careful to allow
enough in the range for all outputs in the interface. For example, if
you set the first zone to address 15, the remaining output contacts on
the controller will be assigned to and respond as Zone 16.
