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
temperature to the selected level by
the beginning of the next program pe-
riod. 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 PRO-
GRAMMING YOUR THERMOSTAT.
• The thermostat is in the HOLD mode.

• The compressor lockout feature is oper-
ating; wait about 5 minutes for system to
begin running. See OPERATING YOUR
