ABSTRACT:
A deicer control circuit wherein a pressurized air source is connected to control valves and a regulating valve. Such regulating valve has a vacuum line output line that is also connected to such control valves. The control valves, on actuation by a timer, will sequence the pressure line and the vacuum line to alternately inflate and deflate the deicer units. The control valves also provide a sealing off or locking in of the pressurized deicer units in this sequence in response to a pressure sensor.
