What are the basic setup requirements for the INNCOM e7w Thermostat?

The e7w thermostat requires four AA alkaline batteries, a smart wall mounting plate, and must be mounted on a standard US single-gang, US double-gang, or UK standard gang junction box. Before operation, you must configure the Room ID, PAN ID, and RF Channel during the initial setup process. The thermostat will enter Initialization Mode on first startup, where you'll configure these parameters one at a time using the arrow buttons and MODE button.
