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.

•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.
