POWER
When the red
AIR FLOW
light is ON, the air flow is too
low for proper operation and the unit has shutoff the power
to the heating elements. This will cause the green
HEATING
light to turn OFF.
If the air flow is restored, the red
AIR FLOW
light will turn
off, the green
HEATING
light will turn back on and the
unit will again heat up.
When the red
OVERTEMP
light is ON, one or more of
three over heating conditions has been reached. The internal
temperature measured at the circuit board has exceeded
140°F, the temperature of the Snout Temperature sensor has
reached 170ºF or the heating element box temperature has
exceeded 210°F. The red OVERTEMP light comes on when
the temperature measured by any one of these sensor
exceeds its set point the unit will shutoff the power to the
heating elements. This will also cause the green
HEATING
light to turn OFF.
When the temperature cools sufficiently the red
OVERTEMP
light will turn off, the green
HEATING
light will turn back on and the unit will again heat up.

In some situations when the air flow is too low and the
AIRFLOW
light comes ON, the E-TES will also over heat
and cause the
OVERTEMP
light to come ON too.
When the air flow is restored the red
AIR FLOW
light will
turn OFF and when the temperature cools sufficiently the
red
OVERTEMP
light will turn OFF, the green
HEATING
light will turn back ON and the unit will again
heat up.
