Before you begin programming 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.

•HOLD TEMPERATURE—The thermostat can hold any tem- perature within its range for an indefinate period, without reverting to the programmed temperature. Press HOLD button. HOLD will be displayed. Then choose the desired

hold temperature by pressing or . The thermostat will hold the room temperature at the selected setting until you press RUN button to start program operation again.

•LOW BATTERY INDICATOR—If the 2 “AAA” alkaline batter- ies are low and should be replaced, the display will be blank except for “LO BATT”. 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 BATT”. You cannot program with low batteries, but you can override setpoint temperature. When “LO BATT” occurs, the thermostat will raise the temperature 10 degrees above your setpoint on “COOL” mode and will drop temperature 10 degrees below your setpoint on “HEAT” mode.

•SIMPLIFIED COPY DAY FUNCTION—This feature allows Monday’s program to be copied into the rest of the week’s programming. This feature is only available the first time you program your thermostat. To use this feature, simply enter the program for Monday as described in PROGRAM- MING YOUR THERMOSTAT, and then press RUN, or HOLD.
