How do I set up the Room ID on the e7w thermostat?

During initial setup, when rId is displayed, press the MODE button to begin. The default Room ID (65535) will scroll across the screen. The Room ID consists of three fields: High value (HI, range 0-6), Medium value (MED, range 0-99), and Low value (LO, range 0-99). Use the UP/DOWN arrow buttons to change each value and press FAN to continue to the next field. After setting all three values, press MODE to store the Room ID.
