STATUS LED Indicator Deﬁnitions

INTELLIGENT SELF--CHECKING CONTROL

Your PTAC has a computer board that continuously checks key components of the unit to ensure they are operating properly. Under normal op-

eration, unit status indicator (STATUS,on main PCB), light is steadily ON. If there is a major problem,the unit will shut down and display a diag-

nostic failure code on the unit’s display. If it is only a minor failure and unit is correcting the fault by itself, the diagnostic code will be ﬂashed on

the status LED that can easily be seen when the front panel is removed (see Fig. C.5.2.3). Failure STATUS codes are deﬁned in the table below.
