The Echo Room Controller Demand Response input requires a normally open dry contact closure. When this contact is closed, it will activate the Demand Response rotary faders and apply the set limits. When the contact is open, the set limits do not apply. You can also set the rotary fader to 0, which will turn the relay off when Demand Response is active. The Echo Room Controller ships with Demand Response set at 50%. If Demand Response is active (contact closed), the Demand Response LED indicator will be lit green. This indicator is found near the blue Power indicator at the bottom of the Echo Room Controller control card. On the Echo Room Controller-Gen 2 product, this indicator is found near the blue Power indicator just under the EchoConnect and Aux connector.
In the Echo Room Controller-Gen 2 products, closing the the Demand Response contact will not only set the Echo Room Controller into Demand Response, but will also broadcast the Demand Response command onto the EchoConnect bus to other products. Echo products manufactured as of April 12, 2018 are capable of responding to the Demand Response command.
