Large Lighted Liquid

Crystal Display (LCD).

The large numbers and letters on your LCD screen make it easy to see. In low light conditions, press the button on top of the thermostat and the display will light up for three seconds. For ten minutes after pressing the light button, pressing any other button will light the display for ten seconds. The display light uses power from the 3 “AA” alkaline batteries installed. Exces- sive use of the display light will reduce battery life.

The thermostat display alternately shows the current time and the current temperature on the left side. The display also shows the temperature you have programmed

or set on the right side of your screen.

Setpoint Range 45-99°F (7-37°C).

You may set your thermostat to any temperature from 45° to 99°F. If you prefer, you may configure the thermostat to display Celsius. This is covered in the CONFIGURA- TION section (page 25, step 9).

Selectable Energy Management Recovery (EMR). 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 heating, the thermostat will start 5 minutes early for every 1°F difference between the

room temperature and the next programmed temperature. In cooling, the thermostat 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 25 minutes early. The difference between the room temperature (65°F) and the setpoint (70°F) is 5°. 5° X 5 minutes per °F

=25 minutes. The setpoint on the display will actually change to display 70° about 25 minutes early.

The maximum time the thermostat can start early in heating is 75 minutes. The maximum time the thermostat can start early in cooling
