How do I enable or disable LEM (Limited Energy Management) mode on the e7w thermostat?

To enable LEM mode, press and hold the Mode button, press and release the Fan button, press and release the Up Arrow button, then release the Mode button. The display will show '(- - -) LE.n' indicating the LEM mode command was sent for 72 hours. To manually disable LEM mode, perform the same sequence but press the Down Arrow button instead of Up Arrow, and the display will show '(- - -) nO.r'. (Pages 35)
