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 system automatically to bring the tem- perature to the selected level by the begin- ning 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 PRO-
GRAMMING YOUR THERMOSTAT.
•The thermostat is in the HOLD mode.
