Operating Features

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

•COMPUTED ENERGY MANAGEMENT RECOVERY (EMR) - The thermostat’s mi- crocomputer 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 pro-

vide 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.

•AUTOMATIC CHANGEOVER — You can set the thermostat to automatically switch the system from heating to cooling as needed. First, you must move option switch #4 (located on the back of the thermostat body) to the ON position, if it has not already been done. To do this, turn off 24 VAC power to the thermostat. Then, remove the thermostat body from the wall. Check the position of switch #4 (the last switch on the right). If it is ON (up), simply put the thermo- stat back on the wall and restore 24 VAC power. If the switch is OFF (down), use a
