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

To enable LEM mode in the HVAC partner from the e7w, 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 '(- - -)' followed by 'LE.n' indicating that the command to enable LEM mode for 72 hours was sent. LEM mode will automatically turn off after 72 hours or when the room is checked out from the front desk if networked with a PMS system.
