rapidly rotate the Adjustor dial back and
forth to enter secondary function mode;
•

actuator motor is called upon to either open or close
the air inlet baffle board, the delay timer as set by the
secondary function (8) must have expired. At this point,
the actuator motor will operate for 30 seconds before
