Fresh / Recirculate. This knob controls the type air, which is circulated by the heater system and fan. By turning clockwise, air is circulated
from the interior of the vehicle. This is desirable when trying to heat passenger compartment rapidly. By turning the control knob counter-
clockwise air from outside the bus is used in the system. This is helpful when trying to cool the vehicle.
Heater Fan. This knob adjusts the speed of the fan, which circulates the air in the system. In the counter clockwise position, the blower is off.
By turning clockwise, 3 speeds can be achieved — low, medium and high.
Defrost / Bus. This knob adjusts the air flow balance between the vehicle passenger compartment and the windshield. By turning knob
clockwise, a damper is moved and air is diverted toward the windshield for defrosting.
Driver / Passenger. This knob Adjusts air flow balance in two directions. By turning knob clockwise, a damper is moved and air is diverted
toward the driver. By turning counterclockwise, the air is diverted toward passengers. The amount of air diverted is proportional to amount
the knob is turned.
