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). This feature provides better efficiency by allowing gradual temperature changes.

For example: The thermostat is programmed to provide an overnight heating temperature of 66°F, and during the next program period, beginning at 6:00 AM, the programmed temperature is 70°F. With EMR activated, the thermostat will

automatically start the heating system at 5:00 AM, so that the programmed temperature of 70°F is reached by about 6:00 AM.

If the overnight room temperature drops only to 68°F, the thermostat will start the system at 5:30 to reach the programmed temperature of 70°F at 6:00.

The thermostat is shipped with the EMR feature active, which means that the thermostat will start the heating system before the beginning of the next program period.

To deactivate the EMR function, see the Configuration menu on Page 5). The thermostat will then wait until the programmed time to start the system for a temperature change.
