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 automatically calculates the time it will take to change the temperature to the next program setting. Then the thermo- stat will activate the heating or cooling sys- tem to change the temperature so that the desired temperature is reached at the be- ginning 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, press | SYSTEM | to turn |
