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.
13. Why doesn’t the temperature change at the
time I programmed?
There may be a number of causes for this
situation. The following are primary reasons.
• The EMR function is operating. The EMR
function will automatically bring on the sys-
tem automatically to bring the temperature
to the selected level by the beginning of the
next program period. See OPERATING
YOUR THERMOSTAT.
• You have programmed the incorrect day or
time. Check your programming (be sure
that the times you programmed are correct
AM or PM times). See PROGRAMMING
YOUR THERMOSTAT.
• The thermostat is in the HOLD mode.
Press RUN

• The compressor lockout feature is operat-
ing; wait about 5 minutes for system to
begin running. See OPERATING YOUR
THERMOSTAT.
14. Why does the blower fan keep running
after the system has turned off?
•
You have programmed the fan to run con-
tinuously during this period. See PRO-
GRAMMING YOUR THERMOSTAT.
