Demand Response Interface:
Activates Demand Response, affecting up four consecutive Echo 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.
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 bottom of page 7.
• 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 EchoAccess 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
Note: Each Echo space can only have one assigned demand
response input.
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.
