Operating Features

Now that you are familiar with the thermostat display and buttons, read the following infor- mation to learn about the many features of the thermostat.

•COMPUTED ENERGY MANAGEMENT RECOVERY (EMR) — The thermostat’s microcomputer automatically calculates the time it will take to change the temperature to the next program setting. Then the ther- mostat will activate the heating or cooling system to change the temperature so that the desired temperature is reached at the beginning of the next program period. As an example of this feature, assume that you have programmed your thermostat to provide an overnight heating temperature

of 62°F, and that during the next program period, beginning at 6:00 AM, you have programmed a temperature of 70°F. The thermostat will automatically activate the heating system at about 5:00 AM, so that the programmed 70°F temperature is reached by about 6:00 AM.

This feature is enabled by option switch #3. To enable the EMR function, you must move option switch #3 (located on the back of the thermostat body) to the ON position.

To do this, press	SYSTEM	until OFF is

displayed on the thermostat. Remove the thermostat body from the wall, turn it over, and check the position of option switch #3. If the switch is ON (up), simply put the thermostat back on the wall and press
