A signal will be sent from the office on the day of operation to each switch. From the office console, York Electric has two-way communications capabilities to send and receive information from the switch. What this means is once we send the command to cycle off a switch, we will be able to see that the switch has received the command and has cycled off the appliance. At the end of our load management operation, we send a second command to the switches to release the appliance from load management, thus allowing the appliance to operate as usual.
