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 microcomputer can be set to automatically calculate the time it will take to change the temperature to the next program setting. Then the thermostat will activate the heat- ing or cooling system to change the tem- perature so that the desired temperature is reached at the beginning of the next pro- gram 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 ac- tivate 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 controlled by Group B option switch #3. To enable the EMR function, first you must move option switch #3 (located on the back of the thermostat body) to the OFF position, if it has not already been done. To do this, turn off 24 VAC power to the thermo- stat. Then remove the thermostat body from the wall. Check the position of switch #3 (the last switch on the right). If it is OFF (down), simply put the thermostat back on the wall and restore 24 VAC power. If the switch is ON (up), remove the battery, then use a pencil or small screwdriver to move the
