Overview

The Echoflex Demand Response Interface is a dedicated contact closure interface that ensures your system can response to Demand Response requests from the power utility. It makes it easy to integrate energy management into any Echoflex system.

Compliance with Demand Response commands from public utilities are written into many of today’s electrical codes, like California’s Title 24 and ASHRAE. These codes affect any facility, new or retrofit, that exceeds 10,000 sq.ft. and lighting wattage exceeding 0.5W sq.ft.

Echoflex’s Demand Response Interface sends a Demand Response command to your lighting system when the input is closed and a DR cancel when the input is open. An on-board LED array indicates Demand Response threshold level and input state.

The control input is driven by any Open ADR appliance with a dry contact output. Once triggered, a command is sent to Echoflex dimming controllers which assigns a temporary maximum dimming level. Linked sensors and switch stations will not drive the dimming output above this new level. The programmed Demand Response event can be canceled at any time or be allowed to time out.

The interface allows Energy Code Acceptance Test technicians to easily trigger the events during system verification. Echoflex controllers will respond immediately so systems can be approved quickly.
