I am reading about ESM's (energy storage modules). Does this have a cap type energy that retains program during power outages? And no battery is needed? Any help would be grateful! Thanks, Scott
You've probably already looked at those. This is all the second link says:
Power and Diagnostic Capabilities
With the launch of these new controllers, we also
introduced the Energy Storage Module (ESM), which
ships with each controller. The ESM eliminates the need
for lithium batteries as well as the the maintenance and
environmental issues associated with the transport and
disposal of lithium batteries.
This one says a little more. Looks like they are capacitor based.
