Thermostat "Energy Mode" What is this?

[CoolToys]

There is a variable with options of "True" or "False" in the admin console when setting up thermostats.  Both thermostats defaulted to false.

I have no idea what this does and entering it verbatim into the Wiki only shows me the thermostat modes which I understand.

Is there a new feature?  Is this part of the electricity module for flex alert? The admin console says to manage the electricity module in the "dashboard" which I do not like as it is over simplified and not easy to use on a mac.  

Thank you.
