12. 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 bring the system on
automatically to bring the temperature
to the selected level by the beginning of
the next program period. See OPER-
ATING 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.
