Adjustable Temperature
Display.
(User menu, Item 1) The room temperature display can be adjusted to read higher or lower by following the User menu and adjusting the temperature to a higher or lower value. The thermostat is calibrated at the factory to display a very accurate room temperature, but due to various conditions and/or personal preference, you may wish to adjust the thermostat display higher or lower (up to 5°F). For example, if the thermostat displays a room temperature of 70° but you want it to display 73°, you can adjust it. To adjust, refer to the CONFIGURA- TION section (page 24, item 1).
Selectable Energy Management Recovery (EMR).
(User menu, Item 2) EMR causes the thermostat to start operating the system early in order to make the building temperature reach your program setpoint at the time you specify. In multistage heating, the thermostat will start 8 minutes early for every 1°F difference between the room temperature and the next programmed temperature. In cooling and heat pump applications, the thermostat uses 15 minutes per °F. For heating applications in large buildings where extra time to reach the set temperature may be desired, EMR Long may be selected. When EMR ON L is selected in the user menu (page 24, item 2) the thermo-

stat uses 15 minutes per °F.
EXAMPLE: If the temperature in the room is 65°F and the thermostat is programmed for 70°F at 7 AM, the thermostat will start approxi- mately 40 minutes early. The difference between the room temperature (65°F) and the setpoint (70°F) is 5°. 5° X 8 minutes per °F
=40 minutes. The setpoint on the display will actually change to display 70° about 40 minutes early.
The maximum time the thermostat can start early in heating is 75 minutes (or 3 hours, 45 minutes if EMR ON L is selected). The maximum time in cooling and heat pump applications is 3 hours and 45 minutes. Cooling or heat pump
