What do the relays do when my Echo Room Controller (ERMC) loses power?

QuestionEdit section

If my Echo Room Controller (ERMC) loses power, what do the relays do?

AnswerEdit section

The relays are mechanically held in whatever position they existed when the controller lost power. If the relays need to be turned on or off while the panel is still without power you can manually flip the relay state simply by moving the switch on the relay itself.
