10.Why won’t the system turn on, even though the thermostat display is functioning nor- mally?
Either the compressor lockout feature is in op- eration or the thermostat is not currently calling for heat or cool. Wait about 5 minutes for the compressor lockout to expire. If the system is still not running, read the cautionary statement be-
low. Then, if conditions permit, use the 
or
buttons to move the temperature above or below the setpoint temperature. See OPERAT-
ING YOUR THERMOSTAT.
!CAUTION
If the outside temperature is below 50°F, DO
NOT use 
or 
to move the tempera- ture above or below the setpoint tempera- ture. 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 situa- tion. 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
RUN | to start program operation. See OP- |
