!CAUTION

If the outside temperature is below 50°F,

DO NOT use the button to move the temperature below the setpoint tem- perature. Property damage may result due to compressor slugging.

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 reasons.

•The EMR function is operating. The EMR function will bring the system on auto- matically to bring the temperature to the selected level by the beginning 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. Press PRGMRUN to start program operation.

See OPERATING YOUR THERMO- STAT.

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