11. 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 rea-
sons.
• The EMR function is operating. The EMR
function will automatically bring on the
system automatically to bring the tem-
perature to the selected level by the
beginning of the next program period.
See OPERATING YOUR THERMO-
STAT.
• 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.
