• System Sentinel
all models employ a
diagnostic panel utilizing
light emitting diodes (L.E.D.),
corresponding to the number
and location of each heating
element. L.E.D.’s are
energized when the electric
elements are operating. An
unlit L.E.D. pinpoints the
exact location of a non-
functioning element, making
element operation diagnosis
simple and positive.
