    INSTALLATION ENERGY MANAGEMENT RECOVERY (EMR) When the EMR feature is activated the thermostat’s microcomputer calculates the time it will take to change the room temperature to the next heat or cool program setting. Then the thermostat will start the system before the next programmed period so that the desired temperature is reached at or near the beginning of the period (the thermostat calculates 15 minutes for every 1°F temperature change).
