What does the LEM (Limited Energy Management) mode do and how do I enable it?

LEM mode expands the guest-selectable temperature range and turns off most energy-saving algorithms for rooms with demanding guests requiring more flexible temperature control. To enable LEM mode from the e7w: Press and hold MODE, press and release FAN, press and release UP arrow, then release MODE. The display will show '(---)' followed by 'LE.n' confirming the command was sent. LEM mode automatically turns off after 72 hours. (Page 35)
