What are the basic installation and mounting requirements for the INNCOM e7w thermostat?

The e7w thermostat requires four AA alkaline batteries, a Smart Wall Mounting Plate, and appropriate screws for installation on standard US single-gang, US double-gang, or UK standard gang junction boxes. The thermostat should be mounted approximately 1.5 meters (5 feet) above the floor in a location with good air circulation, avoiding drafts, direct sunlight, and other RF interference sources. After inserting batteries and mounting, all LCD segments should illuminate briefly to confirm proper installation. (Pages 26-28)
