Control Requirements
EchoConnect
Elaho interface devices require EchoConnect®, Belden 8471 (or equivalent)
plus one ESD ground wire, supporting control signal between the device and
the connected Elaho control system.
EchoConnect is a bidirectional protocol that uses one pair of wires (data+ and
data-) for both data and power. Echoflex 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 1,640feet (500m).
Electrical Requirements
Elaho 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 24-12 AWG (0.2-4 mm2) 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 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 24-12 AWG (0.2 mm2-4 mm2)
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 2,000 feet
(610m) of 18 AWG (1 mm2) 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 24-12 AWG (0.2 mm2- 4 mm2) wire.
Each output includes a corresponding on board LED to indicate the normally
open status of the relay.

closed (NC), then loosen the respective output and COM terminals.
3. Insert the common wire into the “COM” terminal and the output wire
into the respective “NO” or “NC” terminal.
4. Secure the screws firmly onto each wire.
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 Elaho 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: Particularly when considering machine driven applications,
Echoflex 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 Elaho Spaces,
starting with the interface Space rotary switch setting.
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 Elaho space can only have one assigned demand response
input.
Contact and Demand Response Interfaces Page 5 of 8 Echoflex Solutions, Inc.

Echoflex Installation Guide
Contact and Demand Response Interfaces
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 the top of page 8.
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 re-recorded with
new values.
Custom
Custom configuration mode applies the following default behaviors until
changed using the ElahoAccess Mobile App:
Input Interface
Inputs control Presets 1-4 respectively, using maintained input mode where:
•
closing contact activates a preset
•
opening a contact deactivates a preset
Demand Response Interface
Inputs control Spaces determined by settings applied in the ElahoAccess
Mobile App.
Note: Each Elaho space can only have one assigned demand response
input.
Contact and Demand Response Interfaces Page 6 of 8 Echoflex Solutions, Inc.

Echoflex Installation Guide
Contact and Demand Response Interfaces
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
ElahoAccess Mobile App. For detailed information about custom configuration
options available using ElahoAccess, reference the ElahoAccess Mobile App
integrated help system.
Set Space and Address / Zone Start
Interface devices participate in an Elaho 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 an 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 an 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.
Contact and Demand Response Interfaces Page 7 of 8 Echoflex Solutions, Inc.

Echoflex Installation Guide
Contact and Demand Response Interfaces
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.
Power Up
All EchoConnect terminations in the system must be made before applying
power to the system and interface. When the interface is powered up, the
power LED will indicate in blue.
LED States
Input and Demand Response Interface
When a contact is closed, the related status LED will illuminate.
Output Interface
When the normally open contact is closed, the corresponding status LED will
illuminate.
Reset Device
Using a ball point pen, press the [Reset] button to reset the interface, cycling
power and restoring the device to normal operation.
Reset to Factory Defaults
Using a ball point pen, press the [Reset] button for ten seconds to reset the
interface to factory defaults. The power LED will flash when the device has
been restored to its factory defaults.
Remove the Interface from DIN rail
If for any reason you need to remove the interface from the DIN rail, follow
these instructions:
1. Shut off power from the unit.
2. Label, then disconnect all wiring and cap off as necessary.
3. Insert a flat blade screwdriver into the clip on top of the interface,
slide the unit straight up, then pivot the top edge off the DIN rail.
