ENERGY MANAGEMENT INPUT (FRONT DESK CONTROL)
The controller can handle a switch signal from remote energy management input, called EM signal or front
desk control. Input must be 24VAC. If system receives a 24VAC signal, it will turn unit off; otherwise, the
unit runs in normal control. This function will be disabled under Freeze Guard protection. See Fig. 20 and
Fig. 21 for terminal connections.
INTELLIGENT SELF=CHECKING CONTROL
Your Frigidaire PTAC has a computer on-board that continuously checks key components of the unit to ensure
they are operating properly. Under normal operation, 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 diagnostic failure code on
the unit's display. If it is a minor error and the unit can correct it 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.23).
Failure STATUS codes are defined in the table below
