What is LEM Mode and how do I enable or disable it on the e7w?

LEM (Limited Energy Management) Mode expands the guest-selectable temperature range by disabling most energy savings algorithms, useful for guests requiring more flexible temperature control. To enable LEM mode, press and hold MODE, press and release FAN, press and release UP arrow, then release MODE—the display will show 'LE.n' confirming a 72-hour LEM mode was activated. To manually disable it, follow the same sequence but press the DOWN arrow instead of UP—the display will show 'nO.r' for normal mode. (Page 35)
