Installation Guide

–
The remote 500W ERT module is awakened from quiet mode and enters run mode in
one of two ways:
•
Counting two pulses. The pulses are counted internal to the 500W ERT module
while it is in quiet mode.
•
Receiving a two-way command, such as a Read ERT using FDM.
If a remote 500W ERT module installed in quiet mode is not bubbling up SCM+ messages, it
may be due to zero consumption on the remote 500W ERT module , such as a vacant or
vacation home. Initiate a two-way command (for example, perform a Read ERT with FDM)
before removing the unit.
