Introduction
EpiSensor’s ZDR enables customers to participate in multiple Demand and Frequency response programs. It
includes best-in-class functionality to accurately monitor electrical load (via CT’s or pulse inputs), frequency and
can take action to shed load or engage backup generators based on frequency set points or commands sent
from a remote network operations centre.
The system is capable of streaming data securely to a Network Operations Centre (NOC) to arm the system,
detect low frequency events, override the system remotely, and switch loads both automatically and manually.
With a wide range of additional sensors available, EpiSensor’s platform can also be used for energy
management, environmental monitoring and many other applications.
This guide discusses features of the EpiSensor ZDR series demand response controller and provides installation
and configuration instructions.
