If the outside temperature is below 50°F,

DO NOT use the

button to move the

temperature below the setpoint tempera-

ture. Property damage may result due to

compressor slugging.

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.

• The EMR function is operating. The EMR

function will automatically bring on the sys-

tem automatically 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 PROGRAMMING

YOUR THERMOSTAT.

• The thermostat is in the HOLD mode.

Press

See OPERATING YOUR THERMOSTAT.

• The compressor lockout feature is operat-

ing; wait about 5 minutes for system to

begin running. See OPERATING YOUR

THERMOSTAT.

14. Why does the blower fan keep running

after the system has turned off?

• You have programmed the fan to run con-

tinuously during this period. See PRO-

GRAMMING YOUR THERMOSTAT.
