9.The display is flashing BATTERY. What does this mean?
The 9 volt battery installed in the thermostat is low and should be replaced with a fresh 9 volt Energizer® alkaline battery. See OPER-
ATING YOUR THERMOSTAT.
10.Why won’t the system turn on, even though the thermostat display is func- tioning normally?
Either the compressor lockout feature is in operation or the thermostat is not currently calling for heat or cool. Wait about 5 minutes for the compressor lockout to expire. If the system is still not running, read the caution- ary statement at the right. Then, if condi-
tions permit, use the 
or 
buttons to move the temperature above or below the setpoint temperature. See OPERATING YOUR THERMOSTAT.
!CAUTION
If the outside temperature is below 50°F,
DO NOT use the 
button to move the temperature below the setpoint tempera- ture. Property damage may result due to compressor slugging.
11.Why doesn’t the temperature change at the time I programmed?
There are a number of causes for this situ- ation. The following are primary reasons.
•The EMR function is operating. The EMR function will automatically turn on the system early enough to bring the tem- perature to the selected level by the beginning of the next program period. SeeOPERATINGYOURTHERMOSTAT.
