Load Switch
This is used to select the operation of the fill auger. In both the AUTO and MANUAL positions, the load
auger will operate if the dryer is low on grain and will automatically shut OFF when the dryer is full. In the
AUTO position, the dryer will shutdown if the out of grain timer expires. The load delay is disabled
when the Load switch is in the MANUAL position. The switch will illuminate whenever the load auger
is operating.
Fan Switch
The fan is turned ON or OFF with this switch. Turning the switch to the ON position will turn the fan
ON. Turning the switch to the OFF position turns the fan OFF. The light inside the switch will illuminate
whenever the air pressure sensor detects air movement through the fan.
NOTE: The fan AUTO position is not used for continuous flow operation.
Heater Switch
The burner (heater) is turned ON or OFF with this switch. Turning the switch to the ON position will
start the burner ignition sequence if the fan is also running. Turning the switch to the OFF position turns
the burner OFF. The light inside of the switch will illuminate only when the flame sensor detects the
burner flame.
