OPERATING FEATURES
Now that you are familiar with the thermostat display and buttons, read the following information to learn about the many features of the thermostat.
•COMPUTED ENERGY MANAGEMENT RE- COVERY (EMR) — The thermostat’s micro- computer can be set to automatically calculate the time it will take to change the temperature to the next program setting. Then the thermo- stat 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 heat- ing 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 5:00 AM, so that the pro- grammed 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 24v AC power to the thermostat. 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 re- store 24v AC power. If the switch is ON (up), remove the battery, then use a pencil or small screwdriver to move the switch to the OFF position (see figure below). Leave the battery out of the thermostat for at least two minutes, to allow the thermostat to reset itself. See
