CONTINUED FROM THIRD PAGE

Before you begin using your thermostat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons. Your thermostat consists of two parts: the thermostat cover and the base. To remove the cover, gently pull it straight out from the base. To replace the cover, line up the cover with the base and press gently until the cover snaps onto the base.

Operating Features

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.

•SIMULTANEOUS HEATING/COOLING SETPOINT STOR- AGE — You can enter both your heating and cooling setpoints at the same time. There is no need to re-enter the thermostat at the beginning of each season.

•TEMPERATURE SETTING — Press or until the display shows the temperature you want. The thermostat will keep the room temperature at the selected temperature.

•° F/° C CONVERTIBILITY — The factory default setting is Fahrenheit. Clipping W904 jumper on the circuit board (see fig. 1) will alter this feature to Celsius temperature setting.

•LOW BATTERY INDICATOR — If the 2 “AAA” alkaline batteries are low and should be replaced, the display will be blank except for “LO BATTERY”. When the batteries are low, pressing any button will cause the display to operate for ten seconds. After ten seconds, the display will be blank except for

“LO BATTERY”. After “LO BATTERY” has been displayed for 4 weeks, the thermostat will raise the temperature 10° above your setpoint in COOL mode and drop the temperature 10° below your setpoint in HEAT mode. You cannot program with low batteries, but you can override setpoint temperature.
